Detailed Description

A command that has had one or more of its parameters specified. This class serves as a utility class for developers that need to manipulate commands with parameters. It handles the behaviour of generating a parameter map and a human-readable name.

Constructor & Destructor Documentation

◆ ParameterizedCommand()

berry::ParameterizedCommand::ParameterizedCommand	(	const SmartPointer< Command > &	command,
		const QList< Parameterization > &	parameterizations
	)

Constructs a new instance of ParameterizedCommand with specific values for zero or more of its parameters.

Parameters

command	The command that is parameterized; must not be `null`.
parameterizations	An array of parameterizations binding parameters to values for the command. This value may be `null`.

Member Function Documentation

◆ berryObjectMacro()

berry::ParameterizedCommand::berryObjectMacro ( ParameterizedCommand )

◆ ExecuteWithChecks()

Object::Pointer berry::ParameterizedCommand::ExecuteWithChecks	(	const Object::ConstPointer &	trigger,
		const Object::Pointer &	applicationContext
	)

Executes this command with its parameters. This does extra checking to see if the command is enabled and defined. If it is not both enabled and defined, then the execution listeners will be notified and an exception thrown.

Parameters

trigger	The object that triggered the execution; may be `null`.
applicationContext	The state of the application at the time the execution was triggered; may be `null`.

Returns: The result of the execution; may be null.

Exceptions

ExecutionException	If the handler has problems executing this command.
NotDefinedException	If the command you are trying to execute is not defined.
NotEnabledException	If the command you are trying to execute is not enabled.
NotHandledException	If there is no handler.

◆ GenerateCombinations()

static QList<ParameterizedCommand::Pointer> berry::ParameterizedCommand::GenerateCombinations ( const SmartPointer< Command > command )

static

Generates all the possible combinations of command parameterizations for the given command. If the command has no parameters, then this is simply a parameterized version of that command. If a parameter is optional, both the included and not included cases are considered.

If one of the parameters cannot be loaded due to a ParameterValuesException, then it is simply ignored.

Parameters

command The command for which the parameter combinations should be generated; must not be null.

Returns: A collection of ParameterizedCommand instances representing all of the possible combinations. This value is never empty and it is never null.

Exceptions

NotDefinedException If the command is not defined.

◆ GenerateCommand()

static ParameterizedCommand::Pointer berry::ParameterizedCommand::GenerateCommand	(	const SmartPointer< Command >	command,
		const QHash< QString, Object::Pointer > &	parameters
	)

static

Take a command and a map of parameter IDs to values, and generate the appropriate parameterized command.

Parameters

command	The command object. Must not be `null`.
parameters	A map of String parameter ids to objects. May be `null`.

Returns: the parameterized command, or null if it could not be generated

◆ GetCommand()

SmartPointer<Command> berry::ParameterizedCommand::GetCommand ( ) const

Returns the base command. It is possible for more than one parameterized command to have the same identifier.

Returns: The command; never null, but may be undefined.

◆ GetId()

QString berry::ParameterizedCommand::GetId ( ) const

Returns the command's base identifier. It is possible for more than one parameterized command to have the same identifier.

Returns: The command id; never null.

◆ GetName()

QString berry::ParameterizedCommand::GetName ( ) const

Returns a human-readable representation of this command with all of its parameterizations.

Returns: The human-readable representation of this parameterized command; never null.

Exceptions

NotDefinedException If the underlying command is not defined.

◆ GetParameterMap()

QHash<QString, QString> berry::ParameterizedCommand::GetParameterMap ( ) const

Returns the parameter map, as can be used to construct an ExecutionEvent.

Returns: The map of parameter ids (String) to parameter values (String). This map is never null, but may be empty.

◆ HashCode()

uint berry::ParameterizedCommand::HashCode ( ) const

overridevirtual

Returns a hash code value for the object.

Reimplemented from berry::Object.

◆ operator<()

bool berry::ParameterizedCommand::operator< ( const Object * ) const

overridevirtual

Override this method to implement a specific "less than" operator for associative STL containers.

Reimplemented from berry::Object.

◆ operator==()

bool berry::ParameterizedCommand::operator== ( const Object * ) const

overridevirtual

A generic comparison method. Override this method in subclasses and cast to your derived class to provide a more detailed comparison.

Reimplemented from berry::Object.

◆ Serialize()

QString berry::ParameterizedCommand::Serialize ( )

Returns a String containing the command id, parameter ids and parameter values for this ParameterizedCommand . The returned String can be stored by a client and later used to reconstruct an equivalent ParameterizedCommand using the CommandManager.deserialize(String) method.

The syntax of the returned String is as follows:

serialization = commandId [ '(' parameters ')' ]
parameters = parameter [ ',' parameters ]
parameter = parameterId [ '=' parameterValue ]

In the syntax above, sections inside square-brackets are optional. The characters in single quotes ((, ), , and =) indicate literal characters.

commandId represents the command id encoded with separator characters escaped. parameterId and parameterValue represent the parameter ids and values encoded with separator characters escaped. The separator characters (, ), , and = are escaped by prepending a %. This requires % to be escaped, which is also done by prepending a %.

The order of the parameters is not defined (and not important). A missing parameterValue indicates that the value of the parameter is null.

For example, the string shown below represents a serialized parameterized command that can be used to show the Resource perspective:

org.eclipse.ui.perspectives.showPerspective(org.eclipse.ui.perspectives.showPerspective.perspectiveId=org.eclipse.ui.resourcePerspective)

This example shows the more general form with multiple parameters, null value parameters, and escaped = in the third parameter value.

command.id(param1.id=value1,param2.id,param3.id=esc%=val3)

Returns: A string containing the escaped command id, parameter ids and parameter values; never null.

See also: CommandManager::deserialize(String)

◆ ToString()

QString berry::ParameterizedCommand::ToString ( ) const

overridevirtual

Returns a string representation of this object. The default implementation returns an empty string.

Reimplemented from berry::Object.
