		const std::type_info &	ti,
		void *&	ptr,

		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.

overridevirtual

Release an object retrieved from the association.

Parameters

p	The object to release.

Call this when you are done with the object returned by get(). The default implementation is a no-op, but since the association dynamically allocates the object which it returned, this gives it a chance to free it.
