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,

Throws:

IOException

JsonParseException

_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)
                                          throws IOException,
                                                 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

_finishString

protected void _finishString()
                      throws IOException,
                             JsonParseException

Specified by:

_finishString in class JsonParserBase

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)
