Interface ICacheStrategy

All Superinterfaces:

CacheReporter

All Known Implementing Classes:

CacheStrategy, CrosshairStrategy, RectangleStrategy

public interface ICacheStrategy
extends CacheReporter

Interface for cache strategies. A cache strategy identifies which objects should be loaded into the cache, in which order. Unlike ICacheSource, it works with multidimensional (N-D) position arrays rather than rasterized (1-D) indices. The two are made equivalent via a mapping between the two, invoked within Cache as needed.

Method Detail

getLoadList

int[][] getLoadList(int[] pos)
                    throws CacheException

Gets the indices of the objects to cache, surrounding the object at the given position.

Throws:

CacheException

getPriorities

int[] getPriorities()

Retrieves the priority for caching each axis.

setPriority

void setPriority(int priority,
               int axis)

Sets the priority for caching the given axis.

getOrder

int[] getOrder()

Retrieves the order in which objects should be loaded along each axis.

Returns:

An array whose constituents are each one of:

• CENTERED_ORDER
• FORWARD_ORDER
