Method Detail

disables

java.lang.String disables(UsabilityContext<? extends UsabilityEvent> ic)

Whether the rule represented by this facet disables the member to which it applies.

Implementations should use the provided InteractionContext to determine whether they disable the member from being modified or used. They must however guard against a null target and session - neither are guaranteed to be populated.
