Eclipse Platform
Release 3.5

org.eclipse.ui.commands
Interface ICommand

All Superinterfaces:
Comparable

Deprecated. Please use the "org.eclipse.core.commands" plug-in instead.

public interface ICommand
extends Comparable

An instance of ICommand is a handle representing a command as defined by the extension point org.eclipse.ui.commands. The identifier of the handle is identifier of the command being represented.

An instance of ICommand can be obtained from an instance of ICommandManager for any identifier, whether or not a command with that identifier defined in the plugin registry.

The handle-based nature of this API allows it to work well with runtime plugin activation and deactivation. If a command is defined, that means that its corresponding plug-in is active. If the plug-in is then deactivated, the command will still exist but it will be undefined. An attempts to use an undefined command will result in a NotDefinedException being thrown.

This interface is not intended to be extended or implemented by clients.

Since:
3.0
See Also:
ICommandListener, ICommandManager, Command
Restriction:
This interface is not intended to be implemented by clients.

Method Detail

addCommandListener

void addCommandListener(
ICommandListener commandListener)
Deprecated. 
Registers an instance of ICommandListener to listen for changes to attributes of this instance.

Parameters:
commandListener - the instance of ICommandListener to register. Must not be null. If an attempt is made to register an instance of ICommandListener which is already registered with this instance, no operation is performed.

execute


Object execute(
Map parameterValuesByName)
               throws 
ExecutionException,
                      
NotHandledException
Deprecated. 
Executes with the map of parameter values by name.

Parameters:
parameterValuesByName - the map of parameter values by name. Reserved for future use, must be null.
Returns:
the result of the execution. Reserved for future use, must be null.
Throws:
ExecutionException - if an exception occurred during execution.
NotHandledException - if this is not handled.

getAttributeValuesByName


Map getAttributeValuesByName()
                             throws 
NotHandledException
Deprecated. 
Returns the map of attribute values by name.

Notification is sent to all registered listeners if this property changes.

Returns:
the map of attribute values by name. This map may be empty, but is guaranteed not to be null. If this map is not empty, its collection of keys is guaranteed to only contain instances of String.
Throws:
NotHandledException - if this is not handled.

getCategoryId


String getCategoryId()
                     throws 
NotDefinedException
Deprecated. 

Returns the identifier of the category of the command represented by this handle.

Notification is sent to all registered listeners if this attribute changes.

Returns:
the identifier of the category of the command represented by this handle. May be null.
Throws:
NotDefinedException - if the command represented by this handle is not defined.

getDescription


String getDescription()
                      throws 
NotDefinedException
Deprecated. 

Returns the description of the command represented by this handle, suitable for display to the user.

Notification is sent to all registered listeners if this attribute changes.

Returns:
the description of the command represented by this handle. Guaranteed not to be null.
Throws:
NotDefinedException - if the command represented by this handle is not defined.

getId


String getId()
Deprecated. 
Returns the identifier of this handle.

Returns:
the identifier of this handle. Guaranteed not to be null.

getKeySequenceBindings


List getKeySequenceBindings()
Deprecated. 

Returns the list of key sequence bindings for this handle. This method will return all key sequence bindings for this handle's identifier, whether or not the command represented by this handle is defined.

Notification is sent to all registered listeners if this attribute changes.

Returns:
the list of key sequence bindings. This list may be empty, but is guaranteed not to be null. If this list is not empty, it is guaranteed to only contain instances of IKeySequenceBinding.

getName


String getName()
               throws 
NotDefinedException
Deprecated. 

Returns the name of the command represented by this handle, suitable for display to the user.

Notification is sent to all registered listeners if this attribute changes.

Returns:
the name of the command represented by this handle. Guaranteed not to be null.
Throws:
NotDefinedException - if the command represented by this handle is not defined.

isDefined

boolean isDefined()
Deprecated. 

Returns whether or not the command represented by this handle is defined.

Notification is sent to all registered listeners if this attribute changes.

Returns:
true, iff the command represented by this handle is defined.

isHandled

boolean isHandled()
Deprecated. 

Returns whether or not this command is handled. A command is handled if it currently has an IHandler instance associated with it. A command needs a handler to carry out the execute(Map) method.

Notification is sent to all registered listeners if this attribute changes.

Returns:
true, iff this command is enabled.

removeCommandListener

void removeCommandListener(
ICommandListener commandListener)
Deprecated. 
Unregisters an instance of ICommandListener listening for changes to attributes of this instance.

Parameters:
commandListener - the instance of ICommandListener to unregister. Must not be null. If an attempt is made to unregister an instance of ICommandListener which is not already registered with this instance, no operation is performed.
