Class DefaultGeneratedCacheKey

java.lang.Object

org.jsr107.ri.annotations.DefaultGeneratedCacheKey

All Implemented Interfaces:

Serializable, javax.cache.annotation.GeneratedCacheKey

public class DefaultGeneratedCacheKey
extends Object
implements javax.cache.annotation.GeneratedCacheKey

Default cache key implementation. Keeps a reference to a copy of the entire parameter array from the intercepted invocation and uses Arrays.deepHashCode(Object[]) to implement hashCode() and Arrays.deepEquals(Object[], Object[]) to implement equals(Object)

IMPORTANT: This implementation assumes that the entire object graph passed in as the parameters Object[] is immutable. The value returned by hashCode() is calculated in the constructor.
