org.objectledge.pico
Class SequenceParameter

java.lang.Object
  org.objectledge.pico.SequenceParameter

All Implemented Interfaces:

org.picocontainer.Parameter

public class SequenceParameter
extends Object
implements org.picocontainer.Parameter

Allows hinting the component's constructor arguments of aggregated types.

Both Java arrays and java.util.Collection objects are supported. The elements of the sequence are org.picocontainer.Parameter objects - they may resolve to constants, component references, or nested sequences.
