Method Summary

boolean	isSpecializable(java.lang.Object composite, java.lang.Class specializedType) Determines whether the components in the composite can be used to create a specialized version of the composite that implements specializedType.
java.lang.Object	specialize(java.lang.Object composite, java.lang.Class specializedType) Uses the components in the composite to create a composite that implements specializedType and is composed only those

Method Detail

isSpecializable

boolean isSpecializable(java.lang.Object composite,
                        java.lang.Class specializedType)
                        throws SpecializationException

Determines whether the components in the composite can be used to create a specialized version of the composite that implements specializedType.

Parameters:

composite - the composite from which the components will be extracted

specializedType - the type to be exposed

Throws:

SpecializationException - if the new, specialized, composite could not be created

specialize

Uses the components in the composite to create a composite that implements specializedType and is composed only those

Parameters:

composite - the composite from which the components will be extracted

specializedType - the type to be exposed

Throws:

SpecializationException - if the new, specialized, composite could not be created
