Class CacheKernel

java.lang.Object

org.apache.ctakes.ytex.kernel.evaluator.CacheKernel

All Implemented Interfaces:

Kernel, org.springframework.beans.factory.InitializingBean

Direct Known Subclasses:

ProductKernel, SemanticSimKernel, SemanticTypeKernel, SumKernel

public abstract class CacheKernel
extends Object
implements Kernel, org.springframework.beans.factory.InitializingBean

consolidate caching in this class. using AOP is very slow!!! According to the profiler, Class.isInterface() (called by AOP) eats up a large chunk of CPU. Caching is enabled if the cacheName is specified.

By default, we assume that the objects upon which we evaluate the kernel support the Comparable interface. If not, set the cacheKeyGenerator to a different class (default is SymmetricPairCacheKeyGenerator).
