Package org.vast.swe.fast

Class BinaryDataWriter

java.lang.Object

org.vast.swe.fast.DataBlockProcessor

org.vast.swe.fast.AbstractDataWriter

org.vast.swe.fast.BinaryDataWriter

All Implemented Interfaces:

DataComponentVisitor, DataStreamWriter

public class BinaryDataWriter
extends AbstractDataWriter

New implementation of binary 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:

Mar 28, 2022
