Class ScopedParameterResolver

java.lang.Object
com.tangosol.config.expression.ScopedParameterResolver
All Implemented Interfaces:
ParameterResolver, ExternalizableLite, PortableObject, Serializable

public class ScopedParameterResolver extends Object implements ParameterResolver, ExternalizableLite, PortableObject
A ScopedParameterResolver is a ParameterResolver implementation that provides the ability to "scope" Parameter definitions to either an inner (wrapped) or outer ParameterResolver, such that those being defined in the outer ParameterResolver hide those (of the same name) in the inner (wrapped) ParameterResolver.

For example: Parameter "A" defined in the outer ParameterResolver will override and thus "hide" Parameter "A" that is defined in the inner ParameterResolver.
