Class OpMapVector

java.lang.Object
  org.apache.xpath.compiler.OpMapVector

public class OpMapVector
extends java.lang.Object

Like IntVector, but used only for the OpMap array. Length of array is kept in the m_lengthPos position of the array. Only the required methods are in included here.

Field Summary

protected int	m_blocksize Size of blocks to allocate
protected int	m_lengthPos Position where size of array is kept
protected int[]	m_map Array of ints
protected int	m_mapSize Size of array

Constructor Summary

OpMapVector(int blocksize, int increaseSize, int lengthPos)
Construct a OpMapVector, using the given block size.

Method Summary

int	elementAt(int i) Get the nth element.
void	setElementAt(int value, int index) Sets the component at the specified index of this vector to be the specified object.
void	setToSize(int size)

Constructor Detail

OpMapVector

public OpMapVector(int blocksize,
                   int increaseSize,
                   int lengthPos)

Construct a OpMapVector, using the given block size.

Parameters:

blocksize - Size of block to allocate

Method Detail

elementAt

public final int elementAt(int i)

Get the nth element.

Parameters:

i - index of object to get

Returns:

object at given index

setElementAt

public final void setElementAt(int value,
                               int index)

Sets the component at the specified index of this vector to be the specified object. The previous component at that position is discarded. The index must be a value greater than or equal to 0 and less than the current size of the vector.

Parameters:

value - object to set

index - Index of where to set the object

setToSize

public final void setToSize(int size)
