Class TokenBuffer.Segment

java.lang.Object
  com.fasterxml.jackson.databind.util.TokenBuffer.Segment

Enclosing class:

TokenBuffer

protected static final class TokenBuffer.Segment
extends Object

Individual segment of TokenBuffer that can store up to 16 tokens (limited by 4 bits per token type marker requirement). Current implementation uses fixed length array; could alternatively use 16 distinct fields and switch statement (slightly more efficient storage, slightly slower access)

Field Summary

protected TokenBuffer.Segment	_next
protected Object[]	_tokens
protected long	_tokenTypes Bit field used to store types of buffered tokens; 4 bits per token.
static int	TOKENS_PER_SEGMENT

Constructor Summary

TokenBuffer.Segment()

Method Summary

TokenBuffer.Segment	append(int index, com.fasterxml.jackson.core.JsonToken tokenType)
TokenBuffer.Segment	append(int index, com.fasterxml.jackson.core.JsonToken tokenType, Object value)
TokenBuffer.Segment	appendRaw(int index, int rawTokenType, Object value)
Object	get(int index)
TokenBuffer.Segment	next()
int	rawType(int index)
void	set(int index, com.fasterxml.jackson.core.JsonToken tokenType)
