Method Detail

can

public boolean can(fundamentals.signature sgn)

perform

public void perform(fundamentals.signature sgn)

Description copied from class: Operation

The following method performs the operation on the objects given in objs. It's assumed that it makes sense to perform the operation (this can be checked with the can() method. Some subclasses assume that can() method is always called before the perform() method, and that it's called with the same objs Vector.

Specified by:

perform in class Operation

canDefault

public boolean canDefault()

Description copied from class: Operation

Returns true if this method can should be used as a default operation. The default is "true", so we only need to override the method for operations that cannot be used as default operations.

Overrides:
