Package org.vast.swe.fast

Class TextDataParser

java.lang.Object

org.vast.swe.fast.DataBlockProcessor

org.vast.swe.fast.AbstractDataParser

org.vast.swe.fast.TextDataParser

All Implemented Interfaces:

DataComponentVisitor, DataStreamParser

public class TextDataParser
extends AbstractDataParser

New implementation of text data parser with better efficiency since the parsing tree is pre-computed during init instead of being re-evaluated while iterating through the component tree.

Since:

Dec 7, 2016
