Package org.vast.swe.fast

Class XmlDataWriter

java.lang.Object

org.vast.swe.fast.DataBlockProcessor

org.vast.swe.fast.AbstractDataWriter

org.vast.swe.fast.XmlDataWriter

All Implemented Interfaces:

DataComponentVisitor, DataStreamWriter

public class XmlDataWriter
extends AbstractDataWriter

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

Since:

Dec 7, 2016
