All Implemented Interfaces:

JsonParser

public class JsonFastParser
extends JsonParserCharArray

This works in index overlay mode or chop mode. Chop mode reduces possibility of memory leak but causes a few more buffer copies as it chops up the buffer.

Constructor Details

JsonFastParser

public JsonFastParser()

Creates a parser with eager value containers and lazy chopping.

JsonFastParser

public JsonFastParser(boolean useValues)

Creates a parser with the supplied value-container mode.

Parameters:

useValues - whether to use eager Value containers

JsonFastParser

public JsonFastParser(boolean useValues,
 boolean chop)

Creates a parser with explicit chopping behavior.

Parameters:
