Class FixedInterpolatorValueSource

java.lang.Object

org.codehaus.plexus.interpolation.FixedInterpolatorValueSource

All Implemented Interfaces:

ValueSource

public class FixedInterpolatorValueSource
extends java.lang.Object
implements ValueSource

A value source that allows a fixed interpolator to be injected into a regular interpolator. This value source encapsulates state, so even though the fixed interpolator can be used as a singleton, a single FixedInterpolatorValueSource can only belong to one interpolator any given time.
