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)
