Detailed Description

Hidden class for operator instance management.

In this class all operators register on program initialization prior to the run of the main()-function. Afterwards this class can be queried for instances of registered operators, e.g., for generic execution.

The class is encapsulated into a singleton, i.e. not directly accessible from outside.
Instead, refer to the data type ALDOperatorManager for using oeprator manager functionality.

Constructor & Destructor Documentation

Alida::_ALDOperatorManager::_ALDOperatorManager

(

)

[protected]

Default constructor.

The constructor of the operator manager takes care of proper initialization of its operator hash.

virtual Alida::_ALDOperatorManager::~_ALDOperatorManager

(

)

[inline, protected, virtual]

Default destructor.

Member Function Documentation

ALDOperator * Alida::_ALDOperatorManager::getOperator

(

std::string

name

)

Returns operator instance corresponding to provided classname.

This function returns a pointer to the prototype instance of the requested operator.

Parameters:

name	of desired operator.

Returns:

Pointer to a prototype instance, might be NULL.

Definition at line 98 of file ALDOperatorManager.cc.

void Alida::_ALDOperatorManager::printOperatorHash

(

)

Prints the contents of the hash to standard out.

This function prints all registered operator name to standard out.

Definition at line 83 of file ALDOperatorManager.cc.

ALDOperator * Alida::_ALDOperatorManager::registerOperator	(	std::string	name,
		ALDOperator *	op
	)

Registration function for operators.

Each operator that is supposed to be generically executed is required to register itself in this class using this registration function.
The function basically adds a prototype instance of the operator to the manager's operator hash for later reference. In addition, it returns a pointer to the prototype instance to facilitate dynamic registration during a program's initialization phase (refer to Alida::ALDDataIOManager::registerProvider for details on this mechanism).

Parameters:

name	Operator name to be registered.
op	Prototype instance of operator class.

Returns:

Pointer to prototype instance.
