TranslationAction

public TranslationAction(VcObject v,
                         TransformMode mode,

Method Detail

setTranslationValues

public void setTranslationValues(double x,
                                 double y,
                                 double z)

Sets the values by which the VcObject will be translated.

doAction

public void doAction(ActionExecutor executor)

Performs the translation.

Specified by:

doAction in class VcAction

Parameters:

executor - provides any resource necessary for the action execution, such as references to other objects.

optimize

public boolean optimize(VcAction inputAction)

Tries to eliminate the Action given as input, when possible. In case inputAction is not a TranslationAction, then no optimization can be performed and the method returns false. If inputAction is a set to an absolute translation its parameters are simply copied into this object, so inputAction no longer need to be performed. Finally, if inputAction is set to a relative translation, this object's parameters are set to reflect the combined effects of this object and inputAction, which is no longer necessary. In both former cases the method returns true.
