Constructor Detail

ReaderBasedParser

public ReaderBasedParser(IOContext ioCtxt,
                         int features,
                         Reader r,
                         ObjectCodec codec,
                         CharsToNameCanonicalizer st)
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

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 JsonParserMinimalBase
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 JsonParserBase
Throws:
IOException

_parseFieldName

protected final String _parseFieldName(int i)
                                throws IOException,

_handleUnusualFieldName

protected final String _handleUnusualFieldName(int i)
                                        throws IOException,
                                               JsonParseException
Method called when we see non-white space character other than double quote, when expecting a field name. In standard mode will just throw an expection; but in non-standard modes may be able to parse name.

Throws:
IOException
JsonParseException
Since:
1.2

_parseApostropheFieldName

protected final String _parseApostropheFieldName()
                                          throws IOException,

Throws:
IOException
JsonParseException

_handleUnexpectedValue

protected final JsonToken _handleUnexpectedValue(int i)

                                                 JsonParseException
Method for handling cases where first non-space character of an expected value token is not legal for standard JSON content.

Throws:
IOException
JsonParseException
Since:
1.3

protected void _finishString()
                      throws IOException,

_skipString

protected void _skipString()
                    throws IOException,
                           JsonParseException
Method called to skim through rest of unparsed String value, if it is not needed. This can be done bit faster if contents need not be stored for future access.

Throws:
IOException
JsonParseException

_matchToken

protected void _matchToken(JsonToken token)
                    throws IOException,
