Detailed Description

A central repository for commands – both in the defined and undefined states. Commands can be created and retrieved using this manager. It is possible to listen to changes in the collection of commands by attaching a listener to the manager.

Constructor & Destructor Documentation

◆ CommandManager()

berry::CommandManager::CommandManager ( )

The default constructor

Definition at line 164 of file berryCommandManager.cpp.

Member Function Documentation

◆ AddCommandManagerListener()

void berry::CommandManager::AddCommandManagerListener ( ICommandManagerListener * listener )

Adds a listener to this command manager. The listener will be notified when the set of defined commands changes. This can be used to track the global appearance and disappearance of commands.

Parameters

listener The listener to attach; must not be null.

Definition at line 172 of file berryCommandManager.cpp.

References berry::ICommandManagerListener::Events::AddListener().

◆ AddExecutionListener()

void berry::CommandManager::AddExecutionListener ( IExecutionListener * listener )

Adds an execution listener to this manager. This listener will be notified if any of the commands controlled by this manager execute. This can be used to support macros and instrumentation of commands.

Parameters

listener The listener to attach; must not be null.

Definition at line 177 of file berryCommandManager.cpp.

References berry::IExecutionListenerWithChecks::Events::AddListener(), berry::SmartPointer< TObjectType >::Cast(), berry::HandleObjectManager::handleObjectsById, and berry::IExecutionListenerWithChecks::Events::IsEmpty().

◆ DefineUncategorizedCategory()

void berry::CommandManager::DefineUncategorizedCategory	(	const QString &	name,
		const QString &	description
	)

Sets the name and description of the category for uncategorized commands. This is the category that will be returned if getCategory(String) is called with null.

Parameters

name	The name of the category for uncategorized commands; must not be `null`.
description	The description of the category for uncategorized commands; may be `null`.

Definition at line 203 of file berryCommandManager.cpp.

References AUTOGENERATED_CATEGORY_ID, and GetCategory().

◆ Deserialize()

SmartPointer< ParameterizedCommand > berry::CommandManager::Deserialize ( const QString & serializedParameterizedCommand )

Returns a ParameterizedCommand with a command and parameterizations as specified in the provided serializedParameterizedCommand string. The serializedParameterizedCommand must use the format returned by ParameterizedCommand#serialize() and described in the Javadoc for that method.

If a parameter id encoded in the serializedParameterizedCommand does not exist in the encoded command, that parameter id and value are ignored. A given parameter id should not be used more than once in serializedParameterizedCommand. This will not result in an exception, but in this case the value of the parameter when the command is executed is unspecified.

This method will never return null, however it may throw an exception if there is a problem processing the serialization string or the encoded command is undefined.

Parameters

serializedParameterizedCommand a string representing a command id and parameter ids and values; must not be null

Returns: a ParameterizedCommand with the command and parameterizations encoded in the serializedParameterizedCommand; never null.

Exceptions

NotDefinedException	if the command indicated in `serializedParameterizedCommand` is not defined
SerializationException	if there is an error deserializing `serializedParameterizedCommand`
