Method Detail

setMaster

public void setMaster(MMObjectIF master)

Description copied from class: MMHandler

Sets master to be the master MMObjectIF of this MMHandler.

Attention:Although this method is public it is not intended for exhaustive public use. In general methodcall appears when a MMHandler is added to a MMObjectIF (see addHandler in MMObjectIF for more information on this issue).

Overrides:

userDefinedAction

public void userDefinedAction(MMEvent event)

Description copied from class: MMHandler

Implement this method in the user specific implementation of a MMHandler to describe what handler specific action should be done within the doAction method of this MMHandler.

Specified by:

userDefinedAction in class MMHandler

userDefinedFinish

public void userDefinedFinish()

Description copied from class: MMHandler

userDefinedDealsWith

public boolean userDefinedDealsWith(MMEvent event)

Description copied from class: MMHandler

Implement this method in the user specific implementation of a MMHandler to define on which MMEvents this MMHandler shall react.
