Class ReaderBasedParserBase

java.lang.Object

org.codehaus.jackson.JsonParser

org.codehaus.jackson.impl.JsonParserMinimalBase

org.codehaus.jackson.impl.JsonParserBase

org.codehaus.jackson.impl.ReaderBasedParserBase

All Implemented Interfaces:

Closeable, AutoCloseable, Versioned

@Deprecated
public abstract class ReaderBasedParserBase
extends JsonParserBase

Deprecated.

Since 1.9 sub-classes should just include code from here as is.

This is a simple low-level input reader base class, used by JSON parser. The reason for sub-classing (over composition) is due to need for direct access to character buffers and positions.

Field Details

_reader

protected Reader _reader

Deprecated.

Reader that can be used for reading more content, if one buffer from input source, but in some cases pre-loaded buffer is handed to the parser.

_inputBuffer

protected char[] _inputBuffer

Deprecated.

Current buffer from which data is read; generally data is read into buffer from input source.

Constructor Details

ReaderBasedParserBase

protected ReaderBasedParserBase(IOContext ctxt,
 int features,
 Reader r)

Deprecated.

Method Details

releaseBuffered

public int releaseBuffered(Writer w)
                    throws IOException

Deprecated.

Description copied from class: JsonParser

Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given writer if possible; if underlying input is char-based it can released, if not (byte-based) it can not.

Overrides:

releaseBuffered in class JsonParser

Returns:

-1 if the underlying content source is not char-based (that is, input can not be sent to Writer; otherwise number of chars released (0 if there was nothing to release)

Throws:

IOException - if write using Writer threw exception

getInputSource

public Object getInputSource()

Deprecated.

Description copied from class: JsonParser

Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Overrides:

getInputSource in class JsonParser

loadMore

protected final boolean loadMore()
                          throws IOException

Deprecated.

Specified by:

loadMore in class JsonParserBase

Throws:

IOException

getNextChar

protected char getNextChar(String eofMsg)
                    throws IOException,
JsonParseException

Deprecated.

Throws:

IOException

JsonParseException

_closeInput

protected void _closeInput()
                    throws IOException

Deprecated.

Specified by:

_closeInput in class JsonParserBase

Throws:

IOException

_releaseBuffers

protected void _releaseBuffers()
                        throws IOException

Deprecated.

Method called to release internal buffers owned by the base reader. This may be called along with _closeInput() (for example, when explicitly closing this reader instance), or separately (if need be).

Overrides:

_releaseBuffers in class JsonParserBase

Throws:

IOException

_matchToken

protected final boolean _matchToken(String matchStr,
 int i)
                             throws IOException,
JsonParseException

Deprecated.

Helper method for checking whether input matches expected token

Throws:

IOException

JsonParseException

Since:

1.8

_reportInvalidToken

protected void _reportInvalidToken(String matchedPart,
 String msg)
                            throws IOException,
JsonParseException

Deprecated.

Throws:

IOException
