java.lang.Object

bboss.org.apache.velocity.util.introspection.UberspectImpl

bboss.org.apache.velocity.util.introspection.AbstractChainableUberspector

All Implemented Interfaces:

ChainableUberspector, Uberspect, UberspectLoggable

Direct Known Subclasses:

LinkingUberspector

public abstract class AbstractChainableUberspector
extends UberspectImpl
implements ChainableUberspector

Default implementation of a chainable uberspector that forwards all calls to the wrapped uberspector (when that is possible). It should be used as the base class for all chainable uberspectors.

Since:

1.6
