Closeable,AutoCloseable,Versioned
- Direct Known Subclasses:
NonBlockingByteArrayJsonParser,NonBlockingByteBufferJsonParser
Non-blocking parser base implementation for JSON content.
NOTE: only supports parsing of UTF-8 encoded content (and 7-bit US-ASCII since it is strict subset of UTF-8): other encodings are not supported.

_origBufferLen
protected int _origBufferLenIn addition to current buffer pointer, and end pointer, we will also need to know number of bytes originally contained. This is needed to correctly update location information when the block has been completed.

_decodeEscaped
Description copied from class:ParserBaseMethod that sub-classes must implement to support escaped sequences in base64-encoded sections. Sub-classes that do not need base64 support can leave this as is- Overrides:
_decodeEscapedin classParserBase- Returns:
- Character decoded, if any
- Throws:
JacksonException- If escape decoding fails
-
nextToken
Description copied from class:JsonParserMain 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:
nextTokenin classJsonParser- Returns:
- Next token from the stream, if any found, or null to indicate end-of-input
- Throws:
JacksonException- for low-level read issuesStreamReadException- for decoding problems
-
getNextSignedByteFromBuffer
protected abstract byte getNextSignedByteFromBuffer()- Returns:
- next signed byte from the buffer
- Since:
- v2.14
-
getNextUnsignedByteFromBuffer
protected abstract int getNextUnsignedByteFromBuffer()- Returns:
- next unsigned byte from the buffer
- Since:
- v2.14
-
getByteFromBuffer
protected abstract byte getByteFromBuffer(int ptr) - Parameters:
ptr- pointer to byte that is required- Returns:
- byte from the buffer at the given pointer
- Since:
- v2.14
-
_finishToken
Method called when decoding of a token has been started, but not yet completed due to missing input; method is to continue decoding due to at least one more byte being made available to decode.- Returns:
- Token decoded, if complete;
JsonToken.NOT_AVAILABLEif not - Throws:
JacksonException- (generallyStreamReadException) for decoding problems
-
_finishTokenWithEOF
Method similar to_finishToken(), but called when no more input is available, and end-of-input has been detected. This is usually problem case, but not always: root-level values may be properly terminated by this, and similarly trailing white-space may have been skipped.- Returns:
- Token decoded, if complete;
JsonToken.NOT_AVAILABLEif not - Throws:
JacksonException- (generallyStreamReadException) for decoding problems
