Method Detail

getSupportedPropertyDescriptors

protected java.util.List<PropertyDescriptor> getSupportedPropertyDescriptors()

Description copied from class: AbstractConfigurableComponent

Allows subclasses to register which property descriptor objects are supported. Default return is an empty set.

Overrides:

getSupportedPropertyDescriptors in class AbstractConfigurableComponent

Returns:

PropertyDescriptor objects this processor currently supports

getRelationships
