Interface that marks uberspectors as chainable, meaning that multiple uberspectors can be combined in a chain (using the Decorator pattern).

Method Summary

void	wrap(org.apache.velocity.util.introspection.Uberspect inner) Since uberspectors are dynamically enabled using a configuration string, we cannot simply call the constructors to pass the inner uberspector.

Method Detail

wrap

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

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

Parameters:

inner - The decorated uberspector.
