net.sourceforge.pmd.lang.metrics.BasicProjectMemoizer<T,O>

Type Parameters:

T - Type of type declaration nodes of the language

O - Type of operation declaration nodes of the language

ProjectMemoizer<T,O>

public abstract class BasicProjectMemoizer<T extends QualifiableNode,O extends QualifiableNode>
extends java.lang.Object
implements ProjectMemoizer<T,O>

Simple implementation of a project memoizer. Memoizers are accessible in constant time, provided the QualifiedName's hashCode is well distributed.

This implementation takes care of recollecting irrelevant memoizers by storing them in WeakHashMap.
