All Implemented Interfaces:

IndexMap

public class ClipMap

extends ConcreteIndexMap

Use with MultiArrayProxy to limit the bounds of an index to the delegate on a given dimension.

You could "clip" a 2d MultiArray to a window using 2 of these.

Constructor Detail

ClipMap

public ClipMap(int position,
               int low,
               int extent)

Create an IndexMap which clips along a specific dimension. Using this in an MultiArrayProxy will result in the the length of dimension position appearing as extent.

Parameters:

position - the dimension number to clip along

low - the minimum value. 0 will map to this

extent - the new dimension length at position

ClipMap

public ClipMap(ConcreteIndexMap prev,
               int position,
               int low,
               int extent)

Create an IndexMap which clips along a specific dimension and is functionally composed with another IndexMap. Using this in an MultiArrayProxy will result in the the length of dimension position appearing as extent.

Parameters:

prev - IndexMap to be composed with this.

position - the dimension number to clip along

low - the minimum value. 0 will map to this

extent - the new dimension length at position
