Method Detail

getCodec

public ObjectCodec getCodec()

Description copied from class: JsonParser

Accessor for ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

getCodec in class JsonParser

setCodec

public void setCodec(ObjectCodec c)

Description copied from class: JsonParser

Setter that allows defining ObjectCodec associated with this parser, if any. Codec is used by JsonParser.readValueAs(Class) method (and its variants).

Specified by:

setCodec in class JsonParser

version

public Version version()

Description copied from class: JsonParser

Accessor for getting version of the core package, given a parser instance. Left for sub-classes to implement.

Specified by:

version in interface Versioned

Overrides:

version in class ParserMinimalBase

releaseBuffered

public int releaseBuffered(OutputStream out)
                    throws IOException

Description copied from class: JsonParser

Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given stream if possible; if underlying input is byte-based it can released, if not (char-based) it can not.

Overrides:

releaseBuffered in class JsonParser

Returns:

-1 if the underlying content source is not byte based (that is, input can not be sent to OutputStream; otherwise number of bytes released (0 if there was nothing to release)

Throws:

IOException - if write to stream threw exception

getInputSource

public Object getInputSource()

Description copied from class: JsonParser

Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Overrides:

getInputSource in class JsonParser

loadMore

protected final boolean loadMore()
                          throws IOException

Specified by:

loadMore in class ParserBase

Throws:

IOException

_loadToHaveAtLeast

protected final boolean _loadToHaveAtLeast(int minAvailable)
                                    throws IOException

Helper method that will try to load at least specified number bytes in input buffer, possible moving existing data around if necessary

Throws:

IOException

_closeInput

protected void _closeInput()
                    throws IOException

Specified by:

_closeInput in class ParserBase

Throws:

IOException

_releaseBuffers

protected void _releaseBuffers()
                        throws IOException

Method called to release internal buffers owned by the base reader. This may be called along with _closeInput() (for example, when explicitly closing this reader instance), or separately (if need be).

Overrides:

_releaseBuffers in class ParserBase

Throws:

IOException

getText

public String getText()
               throws IOException,
                      JsonParseException

Description copied from class: JsonParser

Method for accessing textual representation of the current token; if no current token (before first call to JsonParser.nextToken(), or after encountering end-of-input), returns null. Method can be called for any token type.

Specified by:

getText in class ParserMinimalBase

Throws:

IOException

JsonParseException

_getText2

protected final String _getText2(JsonToken t)

getTextCharacters

public char[] getTextCharacters()
                         throws IOException,
                                JsonParseException

Description copied from class: JsonParser

Method similar to JsonParser.getText(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

• Textual contents are not guaranteed to start at index 0 (rather, call JsonParser.getTextOffset()) to know the actual offset
• Length of textual contents may be less than the length of returned buffer: call JsonParser.getTextLength() for actual length of returned content.

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over JsonParser.getText()) is to avoid construction of a String object (which will make a copy of contents).

Specified by:

getTextCharacters in class ParserMinimalBase

Throws:

IOException

JsonParseException

getTextLength

public int getTextLength()
                  throws IOException,
                         JsonParseException

Description copied from class: JsonParser

Accessor used with JsonParser.getTextCharacters(), to know length of String stored in returned buffer.

Specified by:

getTextLength in class ParserMinimalBase

Returns:

Number of characters within buffer returned by JsonParser.getTextCharacters() that are part of textual content of the current token.

Throws:

IOException

JsonParseException

getTextOffset

public int getTextOffset()
                  throws IOException,
                         JsonParseException

Description copied from class: JsonParser

Accessor used with JsonParser.getTextCharacters(), to know offset of the first text content character within buffer.

Specified by:

getTextOffset in class ParserMinimalBase

Returns:

Offset of the first character within buffer returned by JsonParser.getTextCharacters() that is part of textual content of the current token.

Throws:

IOException

JsonParseException

getEmbeddedObject

public Object getEmbeddedObject()
                         throws IOException,
                                JsonParseException

Description copied from class: JsonParser

Accessor that can be called if (and only if) the current token is JsonToken.VALUE_EMBEDDED_OBJECT. For other token types, null is returned.

Note: only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees).

Specified by:

getEmbeddedObject in class JsonParser

Throws:

IOException

JsonParseException

getBinaryValue

public byte[] getBinaryValue(Base64Variant b64variant)
                      throws IOException,
                             JsonParseException

Description copied from class: JsonParser

Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JsonParser.getText() and decoding result (except for decoding part), but should be significantly more performant.

Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

Specified by:

getBinaryValue in class ParserMinimalBase

Parameters:

b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).

Returns:

Decoded binary data

Throws:

IOException

JsonParseException

nextToken

public JsonToken nextToken()
                    throws IOException,
                           JsonParseException

Description copied from class: JsonParser

Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.

Specified by:

nextToken in class ParserMinimalBase

Returns:

Next token from the stream, if any found, or null to indicate end-of-input

Throws:

IOException

JsonParseException

close

public void close()
           throws IOException

Description copied from class: JsonParser

Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled. Whether parser owns the input source depends on factory method that was used to construct instance (so check JsonFactory for details, but the general idea is that if caller passes in closable resource (such as InputStream or Reader) parser does NOT own the source; but if it passes a reference (such as File or URL and creates stream or reader it does own them.

Specified by:

close in interface Closeable

Overrides:

close in class ParserBase

Throws:

IOException

nextFieldName

public boolean nextFieldName(SerializableString str)
                      throws IOException,
                             JsonParseException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.FIELD_NAME with specified name and returns result of that comparison. It is functionally equivalent to:

  return (nextToken() == JsonToken.FIELD_NAME) && str.getValue().equals(getCurrentName());

but may be faster for parser to verify, and can therefore be used if caller expects to get such a property name from input next.

Overrides:

nextFieldName in class JsonParser

Parameters:

str - Property name to compare next token to (if next token is JsonToken.FIELD_NAME)

Throws:

IOException

JsonParseException

nextTextValue

public String nextTextValue()
                     throws IOException,
                            JsonParseException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_STRING returns contained String value; otherwise returns null. It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextTextValue in class JsonParser

Throws:

IOException

JsonParseException

nextIntValue

public int nextIntValue(int defaultValue)
                 throws IOException,
                        JsonParseException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 32-bit int value; otherwise returns specified default value It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getIntValue() : defaultValue;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextIntValue in class JsonParser

Throws:

IOException

JsonParseException

nextLongValue

public long nextLongValue(long defaultValue)
                   throws IOException,
                          JsonParseException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 64-bit long value; otherwise returns specified default value It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getLongValue() : defaultValue;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

nextLongValue in class JsonParser

Throws:

IOException

JsonParseException

nextBooleanValue

public Boolean nextBooleanValue()
                         throws IOException,
                                JsonParseException

Description copied from class: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE returns matching Boolean value; otherwise return null. It is functionally equivalent to:

  JsonToken t = nextToken();
  if (t == JsonToken.VALUE_TRUE) return Boolean.TRUE;
  if (t == JsonToken.VALUE_FALSE) return Boolean.FALSE;
  return null;

but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.

Overrides:

Throws:

JsonParseException

parseNumberText

protected final JsonToken parseNumberText(int c)
                                   throws IOException,
                                          JsonParseException

Initial parsing method for number values. It needs to be able to parse enough input to be able to determine whether the value is to be considered a simple integer value, or a more generic decimal value: latter of which needs to be expressed as a floating point number. The basic rule is that if the number has no fractional or exponential part, it is an integer; otherwise a floating point number.

Because much of input has to be processed in any case, no partial parsing is done: all input text will be stored for further processing. However, actual numeric value conversion will be deferred, since it is usually the most complicated and costliest part of processing.

                                     JsonParseException

Slower parsing method which is generally branched to when an escape sequence is detected (or alternatively for long names, or ones crossing input buffer boundary). In any case, needs to be able to handle more exceptional cases, gets slower, and hance is offlined to a separate method.

Throws:

IOException
