Class Capabilities

java.lang.Object
  com.ibm.as400.ui.framework.java.Capabilities

public class Capabilities
extends Object

Defines the capabilities of a DataBean by encapsulating a list of unsupported attributes. Clients of the DataBean can query its associated Capabilities object to learn whether a particular attribute is supported.

A list of instructions, or HandlerTasks, may optionally be associated with each unsupported attribute. These instructions are carried out by the UI framework. Typically they involve disabling or removing certain UI components from a panel.

public void setNotCapable(String attribute,
                          HandlerTask[] handlerTasks)

The HandlerTasks indicate which panel components are affected by the unsupported attribute, and what action should be taken on them.

Parameters:

attribute - the attribute for which the indication is to be set

Parameters:

attribute - the attribute to be checked

Returns:

true if the DataBean supports the specified attribute; false otherwise.

getHandlerTasksFor

public HandlerTask[] getHandlerTasksFor(String attribute)

Returns a list of HandlerTasks associated with an unsupported attribute. If the attribute is supported, or if there are no HandlerTasks associated with the attribute, this method returns an array of length 0.
