Method Detail

deriveDefinition

protected void deriveDefinition(S_LibraryObjectDefinition def)
                         throws IfsException

Add to the S_LibraryObjectDefinition for this class. This this called by getDefinition() on S_LibraryObject. This must call super.deriveDefinition() before applying any class-specific changes to the S_LibraryObjectDefinition object.

Overrides:

deriveDefinition in class S_PublicObject

Parameters:

def - the S_LibraryObjectDefinition that contains the definition of the target object.

Throws:

IfsException - if operation fails.
