Field Detail

_icLatin1

protected static final int[] _icLatin1

_origBufferLen

protected int _origBufferLen

In addition to current buffer pointer, and end pointer, we will also need to know number of bytes originally contained. This is needed to correctly update location information when the block has been completed.

Constructor Detail

NonBlockingUtf8JsonParserBase

protected NonBlockingUtf8JsonParserBase(IOContext ctxt,
                                        int parserFeatures,
                                        ByteQuadsCanonicalizer sym)

Method Detail

needMoreInput

public final boolean needMoreInput()

endOfInput

public void endOfInput()

_decodeEscaped

protected char _decodeEscaped()
                       throws IOException

Description copied from class: ParserBase

Method that sub-classes must implement to support escaped sequences in base64-encoded sections. Sub-classes that do not need base64 support can leave this as is

Overrides:

_decodeEscaped in class ParserBase

Returns:

Character decoded, if any

Throws:

IOException - If escape decoding fails

nextToken

public JsonToken nextToken()
                    throws IOException

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 - for low-level read issues, or JsonParseException for decoding problems

getNextSignedByteFromBuffer

protected abstract byte getNextSignedByteFromBuffer()

Returns:

next signed byte from the buffer

Since:

v2.14

getNextUnsignedByteFromBuffer

protected abstract int getNextUnsignedByteFromBuffer()

Returns:

next unsigned byte from the buffer

Since:

v2.14

getByteFromBuffer

protected abstract byte getByteFromBuffer(int ptr)

Parameters:

ptr - pointer to byte that is required

Returns:

byte from the buffer at the given pointer

Since:

v2.14

_finishToken

protected final JsonToken _finishToken()
                                throws IOException

Method called when decoding of a token has been started, but not yet completed due to missing input; method is to continue decoding due to at least one more byte being made available to decode.

Returns:

Token decoded, if complete; JsonToken.NOT_AVAILABLE if not

Throws:

IOException - (generally JsonParseException) for decoding problems

_finishTokenWithEOF

protected final JsonToken _finishTokenWithEOF()
                                       throws IOException

Method similar to _finishToken(), but called when no more input is available, and end-of-input has been detected. This is usually problem case, but not always: root-level values may be properly terminated by this, and similarly trailing white-space may have been skipped.

Returns:

Token decoded, if complete; JsonToken.NOT_AVAILABLE if not

Throws:

IOException - (generally JsonParseException) for decoding problems

_startUnexpectedValue
