Class ByteSourceJsonBootstrapper
java.lang.Object
com.fasterxml.jackson.core.json.ByteSourceJsonBootstrapper
public final class ByteSourceJsonBootstrapper
- extends Object
This class is used to determine the encoding of byte stream
that is to contain JSON content. Rules are fairly simple, and
defined in JSON specification (RFC-4627 or newer), except
for BOM handling, which is a property of underlying
streams.

_context
protected final IOContext _context
_in
protected final InputStream _in
_inputBuffer
protected final byte[] _inputBuffer
_inputProcessed
protected int _inputProcessed
- Current number of input units (bytes or chars) that were processed in
previous blocks,
before contents of current input buffer.
Note: includes possible BOMs, if those were part of the input.
_bigEndian
protected boolean _bigEndian
_bytesPerChar
protected int _bytesPerChar
ByteSourceJsonBootstrapper
public ByteSourceJsonBootstrapper(IOContext ctxt,
InputStream in)
ByteSourceJsonBootstrapper
public ByteSourceJsonBootstrapper(IOContext ctxt,
byte[] inputBuffer,
int inputStart,
int inputLen)
detectEncoding
public JsonEncoding detectEncoding()
throws IOException,
JsonParseException
- Method that should be called after constructing an instace.
It will figure out encoding that content uses, to allow
for instantiating a proper scanner object.
- Throws:
IOException
JsonParseException
constructReader
public Reader constructReader()
throws IOException
- Throws:
IOException
constructParser
public JsonParser constructParser(int parserFeatures,
ObjectCodec codec,
BytesToNameCanonicalizer rootByteSymbols,
CharsToNameCanonicalizer rootCharSymbols,
boolean canonicalize,
boolean intern)
throws IOException,
JsonParseException
- Throws:
IOException
JsonParseException
hasJSONFormat
public static MatchStrength hasJSONFormat(InputAccessor acc)
throws IOException
- Current implementation is not as thorough as other functionality
(
ByteSourceJsonBootstrapper
);
supports UTF-8, for example. But it should work, for now, and can
be improved as necessary.
- Throws:
IOException
ensureLoaded
protected boolean ensureLoaded(int minimum)
throws IOException
- Throws:
IOException
