Detailed Description

Non-template parts of MultiAssociationTool.

The class MultiAssociationTool provides a type-safe wrapper for the IMultiAssociationTool interface; it is templated on the types of the source and target of the association. This class serves as a common base class for the MultiAssociationTool instantiations, and factors out all the code that doesn't depend on the template argument.

Derived classes should define fromTypeinfo (this is normally done by MultiAssociationTool). The book method may also be overridden if the tool should itself fill any tuple variables.

Constructor & Destructor Documentation

MultiAssociationToolImpl()

D3PD::MultiAssociationToolImpl::MultiAssociationToolImpl	(	const std::string &	type,
		const std::string &	name,
		const IInterface *	parent )

Standard Gaudi tool constructor.

Parameters

type	The name of the tool type.
name	The tool name.
parent	The tool's Gaudi parent.

Definition at line 27 of file MultiAssociationToolImpl.cxx.

addDimensionedVariable() [1/3]

StatusCode D3PD::AddVariable::addDimensionedVariable ( const std::string & name, const std::type_info & ti, void *& ptr, const std::string & dim, const std::string & docstring = "", const void * defval = 0 )

virtualinherited

Add a variable to the tuple.

Parameters

name	The name of the variable.
type	The type of the variable.
ptr	Pointer to the type of the variable. The pointer need not be initialized; the D3PD software will set the pointer prior to calling fill().
dim	Dimension for the variable. (Presently unimplemented!)
docstring	Documentation string for this variable.
defval	Pointer to the default value to use for this variable. Null for no default (generally means to fill with zeros). Of the type given by ti. Only works for basic types.

If called from the constructor, the only effect is to clear ptr.
