public abstract class AbstractChainableUberspector
extends org.apache.velocity.util.introspection.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.

1.5M1

wrap

public void wrap(org.apache.velocity.util.introspection.Uberspect inner)

Description copied from interface: ChainableUberspector

Since uberspectors are dynamically enabled using a configuration string, we cannot simply call the constructors to pass the inner uberspector. We can either instantiate uberspectors using reflection and passing the wrapped object to the constructor, or explicitely "wrap" the inner uberspector. The second method has several advantages, so it was chosen here:

• Doesn't require adding an extra constructor
• Keeps the initialization process a bit more simple
• Allows the wrapping to take place at a different time

Specified by:

wrap in interface ChainableUberspector

inner - The decorated uberspector.
