## Member Function Documentation

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)

|  | 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)
