IToolSvc::DeclareInterfaceID	(	IToolSvc	,
		2	,
		1
	)

InterfaceID.

virtual std::vector<std::string> IToolSvc::getInstances ( const std::string & toolType )

pure virtual

Get the names of all instances of tools of a given type.

Parameters

toolType type of tool

virtual std::vector<std::string> IToolSvc::getInstances ( ) const

pure virtual

Get the names all tool instances.

virtual std::vector<IAlgTool*> IToolSvc::getTools ( ) const

pure virtual

Get pointers to all tool instances.

virtual void IToolSvc::registerObserver ( Observer * obs )

pure virtual

virtual StatusCode IToolSvc::releaseTool ( IAlgTool * tool )

pure virtual

Release the tool.

Parameters

tool	to be released

virtual StatusCode IToolSvc::retrieve	(	const std::string &	type,
		const InterfaceID &	iid,
		IAlgTool *&	tool,
		const IInterface *	parent = `0`,
		bool	createIf = `true`
	)

pure virtual

Retrieve tool with tool dependent part of the name automatically assigned.

By default a tool will be created if it does not exist, unless otherwise specified. By default it will be a common tool unless a parent is specified. The parent of a common tool is automatically taken as the ToolSvc itself.

Parameters

type	AlgTool type name
iid	the unique interface identifier
tool	returned tool
parent	constant reference to the parent (def=none)
createIf	creation flag (def=create if not existing)

virtual StatusCode IToolSvc::retrieve	(	const std::string &	type,
		const std::string &	name,
		const InterfaceID &	iid,
		IAlgTool *&	tool,
		const IInterface *	parent = `0`,
		bool	createIf = `true`
	)

pure virtual

Retrieve tool with tool dependent part of the name specified by the requester.

By default a tool will be created if it does not exist, unless otherwise specified. By default it will be a common tool unless a parent is specified. The parent of a common tool is automatically taken as the ToolSvc itself.

Parameters

type	AlgTool type name
name	name to be assigned to tool dependent part of the name
iid	the unique interface identifier
tool	returned tool
parent	constant reference to parent (def=none)
createIf	creation flag (def=create if not existing)

template<class T >

StatusCode IToolSvc::retrieveTool	(	const std::string &	type,
		T *&	tool,
		const IInterface *	parent = `nullptr`,
		bool	createIf = `true`
	)

inline

Retrieve specified tool sub-type with tool dependent part of the name automatically assigned.

Internally it uses the corresponding IToolSvc::retrieve and does the dynamic casting.

IToolSvc* svc  = ... ;
IMyTool*  tool = 0   ;
StatusCode sc = svc->retrieveTool ( "MyToolType" , tool ) ;

For this example public tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be ToolSvc.MyToolType

IToolSvc*   svc = ... ;
IAlgorithm* alg = ... ;
IMyTool*  tool  = 0   ;
StatusCode sc   = svc->retrieveTool ( "MyToolType" , tool , alg ) ;

For this example the private tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be <AlgName>.MyToolType , where <AlgName> is a name of the algorithm.

IToolSvc* svc  = ... ;
IMyTool*  tool = 0   ;
StatusCode sc = svc->retrieveTool ( "MyToolType/MyToolName" , tool ) ;

For this example public tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be ToolSvc.MyToolName

IToolSvc*   svc = ... ;
IAlgorithm* alg = ... ;
IMyTool*  tool  = 0   ;
StatusCode sc   = svc ->
              retrieveTool ( "MyToolType/MyToolName" , tool , alg ) ;

For this example the private tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be <AlgName>.MyToolName , where <AlgName> is a name of the algorithm.

Parameters

tool	returned tool
parent	constant reference to parent (def=none)
createIf	creation flag (def=create if not existing)

     return retrieve( type, T::interfaceID(), (IAlgTool*&)tool, parent, createIf );

		const std::string &	name,
		T *&	tool,
		const IInterface *	parent = `nullptr`,
		bool	createIf = `true`
	)

inline

Retrieve specified tool sub-type with tool dependent part of the name tool dependent part of the name specified by the requester.

Internally it uses the corresponding IToolSvc::retrieve and does the dynamic casting.

IToolSvc* svc  = ... ;
IMyTool*  tool = 0   ;
StatusCode sc = svc->retrieveTool ( "MyToolType" ,
                                    "MyToolName" , tool ) ;

For this example public tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be ToolSvc.MyToolName

IToolSvc*   svc = ... ;
IAlgorithm* alg = ... ;
IMyTool*  tool  = 0   ;
StatusCode sc   = svc->retrieveTool ( "MyToolType" ,
                                      "MyToolName" , tool , alg ) ;

For this example the private tool of type 'MyToolType' will be retrieved from Tool Service (created on demand). The full name of the tool instance is set to be <AlgName>.MyToolName , where <AlgName> is a name of the algorithm.

If name is empty ("") it is assumed to be equal to the type

Parameters

type	AlgTool type name
name	name to be assigned to tool dependent part of the name
tool	returned tool
parent	constant reference to parent (def=none)
createIf	creation flag (def=create if not existing)
