Class NodeRecorderHuge

java.lang.Object
  com.ximpleware.extended.NodeRecorderHuge

public class NodeRecorderHuge
extends Object

NodeRecorderHuge allows one to record the node position of VTDNavHuge. However, the internal representation of node is variable in length and recording a large number of nodes could consume much memory. It is a bad idea to record every node of an document. So be careful when using it.

Field Summary

static int	BUF_SZ_EXPO
protected FastIntBuffer	fib
protected VTDNavHuge	vn

Constructor Summary

NodeRecorderHuge()
The parameter-less constructor

NodeRecorderHuge(VTDNavHuge vn1)

Method Summary

void	bind(VTDNavHuge vn1)
void	clear() Clear will erase all the nodes, internal buffers are reused
int	iterate() This method set the cursor in VTDNav to the nodes as recorded in NodeRecorder, and return the output of "getCurrentIndex()" It is important to notice that you can only go forward, not backward
void	record() This function records the position of VN into an internal buffer
void	resetPointer() resetPointer() will set the pointer to the first node in NodeRecorder This method is called when one wants to read the nodes in the nodeRecorder
