HashMapModules

public HashMapModules()

Method Detail

getMaxKey

public int getMaxKey()

Find maximum value in set of keys contained in this map.

Returns:

Maximum key.

put

public InfoModule put(java.lang.Integer key,
                      InfoModule module)

Associates the module (or group) with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced.

Specified by:

put in interface java.util.Map<java.lang.Integer,InfoModule>

Overrides:

put in class java.util.HashMap<java.lang.Integer,InfoModule>

Parameters:

key - Module's key.

module - Module's info.

Returns:

previous module associated with specified key, or null if there was no mapping for key. A null return can also indicate that the HashMap previously associated null with the specified key.

remove

public InfoModule remove(java.lang.Integer key)

Removes the mapping for this key from this map if present. If the map previously contained a mapping for this key, the old value is replaced.

Parameters:

key - Module's key.

Returns:

previous module associated with specified key, or null if there was no mapping for key. A null return can also indicate that the HashMap previously associated null with the specified key.

changePerformed

public void changePerformed(int id,
                            InfoModule _obj)

Group change - add/delete module.

Parameters:

id - Identification of action.

_obj - Module.

addActionListener

public void addActionListener(java.awt.event.ActionListener l)

Adds the specified action listener to receive action events from this object. Action events occur when any action is performed. If l is null, no exception is thrown and no action is performed.

Parameters:

l - the action listener

See Also:

removeActionListener(java.awt.event.ActionListener), ActionListener

removeActionListener

public void removeActionListener(java.awt.event.ActionListener l)

Removes the specified action listener so that it no longer receives action events from this object. If l is null, no exception is thrown and no action is performed.

Parameters:

l - the action listener

See Also:

addActionListener(java.awt.event.ActionListener), ActionListener

processActionEvent

protected void processActionEvent(java.awt.event.ActionEvent e)

Processes action events occurring on this object by dispatching them to any registered ActionListener objects.

This method is not called unless action events are enabled for this object. Action events are enabled when one of the following occurs:

• An ActionListener object is registered via addActionListener(java.awt.event.ActionListener).
• Action events are enabled via enableEvents.

Note that if the event parameter is null the behavior is unspecified and may result in an exception.

Parameters:

e - the action event
