Class XMLMemMappedBuffer

java.lang.Object
  com.ximpleware.extended.XMLMemMappedBuffer

All Implemented Interfaces:

com.ximpleware.extended.IByteBuffer

public class XMLMemMappedBuffer
extends java.lang.Object
implements com.ximpleware.extended.IByteBuffer

XMLMemMappedBuffer maps an XML document into memory using memory map. It avoids the complete loading of the document in memory thus making it possible to process very large files. But the trade off is potentially lower performance due to disk IO.
