Detailed Description

A token representing the activation of a handler. This token can later be used to cancel that activation. Without this token, then handler will only become inactive if the component in which the handler was activated is destroyed.

This interface is not intended to be implemented or extended by clients.

berry::IHandlerActivation::berryObjectMacro

(

berry::IHandlerActivation

)

virtual void berry::IHandlerActivation::ClearActive ( )

pure virtual

Clears the cached computation of the isActive method, if any. This method is only intended for internal use. It provides a mechanism by which ISourceProvider events can invalidate state on a IHandlerActivation instance.

Deprecated:

Use IEvaluationResultCache#clearResult() instead.

virtual QString berry::IHandlerActivation::GetCommandId ( ) const

pure virtual

Returns the identifier of the command whose handler is being activated.

Returns

The command identifier; never null.

virtual int berry::IHandlerActivation::GetDepth ( ) const

pure virtual

Returns the depth at which this activation was created within the services hierarchy. The root of the hierarchy is at a depth of 1. This is used as the final tie-breaker in the event that no other method can be used to determine a winner.

Returns

The depth at which the handler was inserted into the services hierarchy; should be a positive integer.

virtual SmartPointer<IHandler> berry::IHandlerActivation::GetHandler ( ) const

pure virtual

Returns the handler that should be activated.

Returns

The handler; may be null.

virtual IHandlerService* berry::IHandlerActivation::GetHandlerService ( ) const

pure virtual

Returns the handler service from which this activation was requested. This is used to ensure that an activation can only be retracted from the same service which issued it.

Returns

The handler service; never null.
