字段详细资料

_objectCodec

protected ObjectCodec _objectCodec

Codec used for data binding when (if) requested.

_mayContainRawBinary

protected boolean _mayContainRawBinary

Flag that indicates whether content can legally have raw (unquoted) binary data. Since this information is included both in header and in actual binary data blocks there is redundancy, and we want to ensure settings are compliant. Using application may also want to know this setting in case it does some direct (random) access.

_smileBufferRecycler

protected final SmileBufferRecycler<String> _smileBufferRecycler

Helper object used for low-level recycling of Smile-generator specific buffers.

从以下版本开始:

1.7

_inputStream

protected InputStream _inputStream

Input stream that can be used for reading more content, if one in use. May be null, if input comes just as a full buffer, or if the stream has been closed.

_inputBuffer

protected byte[] _inputBuffer

Current buffer from which data is read; generally data is read into buffer from input source, but in some cases pre-loaded buffer is handed to the parser.

_bufferRecyclable

protected boolean _bufferRecyclable

Flag that indicates whether the input buffer is recycable (and needs to be returned to recycler once we are done) or not.

If it is not, it also means that parser can NOT modify underlying buffer.

_tokenIncomplete

protected boolean _tokenIncomplete

Flag that indicates that the current token has not yet been fully processed, and needs to be finished for some access (or skipped to obtain the next token)

_typeByte

protected int _typeByte

Type byte of the current token

_got32BitFloat

protected boolean _got32BitFloat

Specific flag that is set when we encountered a 32-bit floating point value; needed since numeric super classes do not track distinction between float and double, but Smile format does, and we want to retain that separation.

_symbols

protected final BytesToNameCanonicalizer _symbols

Symbol table that contains field names encountered so far

_quadBuffer

protected int[] _quadBuffer

Temporary buffer used for name parsing.

_quad1

protected int _quad1

Quads used for hash calculation

_quad2

protected int _quad2

Quads used for hash calculation

_seenNames

protected String[] _seenNames

Array of recently seen field names, which may be back referenced by later fields. Defaults set to enable handling even if no header found.

_seenNameCount

protected int _seenNameCount

_seenStringValues

protected String[] _seenStringValues

Array of recently seen field names, which may be back referenced by later fields Defaults set to disable handling if no header found.

                           throws IOException,
                                  JsonParseException

Helper method called when it looks like input might contain the signature; and it is necessary to detect and handle signature to get configuration information it might have.

_smileBufferRecycler

protected static final SmileBufferRecycler<String> _smileBufferRecycler()

从以下版本开始:

1.7

releaseBuffered

public int releaseBuffered(OutputStream out)
                    throws IOException

从类复制的说明: 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 stream if possible; if underlying input is byte-based it can released, if not (char-based) it can not.

覆盖:

releaseBuffered 在类中 JsonParser

返回:

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

抛出:

IOException - if write to stream threw exception

getInputSource

public Object getInputSource()

从类复制的说明: 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.

覆盖:

getInputSource 在类中 JsonParser

getTokenLocation

public JsonLocation getTokenLocation()

Overridden since we do not really have character-based locations, but we do have byte offset to specify.

覆盖:

抛出:

IOException

JsonParseException

close

public void close()
           throws IOException

从类复制的说明: 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.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 JsonParserBase

抛出:

IOException

hasTextCharacters

public boolean hasTextCharacters()

从类复制的说明: JsonParser

Method that can be used to determine whether calling of JsonParser.getTextCharacters() would be the most efficient way to access textual content for the event parser currently points to.

Default implementation simply returns false since only actual implementation class has knowledge of its internal buffering state. Implementations are strongly encouraged to properly override this method, to allow efficient copying of content by other code.

覆盖:

hasTextCharacters 在类中 JsonParserBase

返回:

True if parser currently has character array that can be efficiently returned via JsonParser.getTextCharacters(); false means that it may or may not exist

_releaseBuffers

protected void _releaseBuffers()
                        throws IOException

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).

覆盖:

_releaseBuffers 在类中 JsonParserBase

抛出:

                      throws IOException,
                             JsonParseException

从类复制的说明: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.FIELD_NAME with specified name and returns result of that comparison. It is functionally equivalent to:

从类复制的说明: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_STRING returns contained String value; otherwise returns null. It is functionally equivalent to:

  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;

从类复制的说明: JsonParser

Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE returns matching Boolean value; otherwise return null. It is functionally equivalent to:

  JsonToken t = nextToken();
  if (t == JsonToken.VALUE_TRUE) return Boolean.TRUE;
  if (t == JsonToken.VALUE_FALSE) return Boolean.FALSE;

getText

public String getText()

                         throws IOException,
                                JsonParseException

从类复制的说明: JsonParser

Method similar to JsonParser.getText(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

• Textual contents are not guaranteed to start at index 0 (rather, call JsonParser.getTextOffset()) to know the actual offset
• Length of textual contents may be less than the length of returned buffer: call JsonParser.getTextLength() for actual length of returned content.

Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

The only reason to call this method (over JsonParser.getText()) is to avoid construction of a String object (which will make a copy of contents).

指定者:

getTextLength

public int getTextLength()
                  throws IOException,

从类复制的说明: JsonParser

Accessor used with JsonParser.getTextCharacters(), to know length of String stored in returned buffer.

指定者:

返回:

Number of characters within buffer returned by JsonParser.getTextCharacters() that are part of textual content of the current token.

                      throws IOException,
                             JsonParseException

从类复制的说明: JsonParser

Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JsonParser.getText() and decoding result (except for decoding part), but should be significantly more performant.

Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

指定者:

getBinaryValue 在类中 JsonParserMinimalBase

参数:

b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).

返回:

Accessor that can be called if (and only if) the current token is JsonToken.VALUE_EMBEDDED_OBJECT. For other token types, null is returned.

Note: only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees).

从类复制的说明: JsonParserBase

Method that will parse actual numeric value out of a syntactically valid number value. Type it will parse into depends on whether it is a floating point number, as well as its magnitude: smallest legal type (of ones available) is used for efficiency.

覆盖:

_parseNumericValue 在类中 JsonParserBase

参数:

expType - Numeric type that we will immediately need, if any; mostly necessary to optimize handling of floating point numbers
