Method Summary

Modifier and Type	Method and Description
JsonParser	createParserWithMatch() Convenience method for trying to construct a JsonParser for parsing content which is assumed to be in detected data format.
InputStream	getDataStream() Method to use for accessing input for which format detection has been done.
String	getMatchedFormatName() Accessor for getting brief textual name of matched format if any (null if none).
MatchStrength	getMatchStrength() Method for accessing strength of the match, if any; if no match, will return MatchStrength.INCONCLUSIVE.
ObjectReader	getReader() Accessor for JsonFactory that represents format that data matched.
boolean	hasMatch() Accessor to use to see if any formats matched well enough with the input data.

protected final InputStream _originalStream

_bufferedData

protected final byte[] _bufferedData

Content read during format matching process

_bufferedStart

protected final int _bufferedStart

Pointer to the first byte in buffer available for reading

_bufferedLength

protected final int _bufferedLength

Number of bytes available in buffer.

_match

protected final ObjectReader _match

Factory that produced sufficient match (if any)

_matchStrength

protected final MatchStrength _matchStrength

Strength of match with _match

Constructor Detail

Match

protected Match(InputStream in,
                byte[] buffered,
                int bufferedStart,
                int bufferedLength,
                ObjectReader match,
                MatchStrength strength)

Method Detail

hasMatch

public boolean hasMatch()

Accessor to use to see if any formats matched well enough with the input data.

getMatchStrength

public MatchStrength getMatchStrength()

Method for accessing strength of the match, if any; if no match, will return MatchStrength.INCONCLUSIVE.

getReader

public ObjectReader getReader()

Accessor for JsonFactory that represents format that data matched.

getMatchedFormatName

public String getMatchedFormatName()

Accessor for getting brief textual name of matched format if any (null if none). Equivalent to:

   return hasMatch() ? getMatch().getFormatName() : null;

createParserWithMatch

public JsonParser createParserWithMatch()
                                 throws IOException

Convenience method for trying to construct a JsonParser for parsing content which is assumed to be in detected data format. If no match was found, returns null.

Throws:

IOException

getDataStream

public InputStream getDataStream()

Method to use for accessing input for which format detection has been done. This must be used instead of using stream passed to detector unless given stream itself can do buffering. Stream will return all content that was read during matching process, as well as remaining contents of the underlying stream.
