Constructor & Destructor Documentation

Request()

OGF::Request::Request	(	Object *	o,
		MetaMethod *	m,
		bool	managed = true
	)

Request constructor.

Parameters

[in]	o	a pointer to the target object.
[in]	m	a pointer to the target method.
[in]	managed	if true, then reference count is increased/decreased for object.

Member Function Documentation

get_doc()

std::string OGF::Request::get_doc ( ) const

overridevirtual

Gets the documentation.

Returns

A string with a human-readable documentation about this object.

Reimplemented from OGF::Object.

invoke()

bool OGF::Request::invoke ( const ArgList &  args, Any &  ret_val  )

overridevirtual

Invokes a method by method name.

This variant of invoke() is for methods with no argument and void return type.

Return values

true	if the method could be sucessfully invoked
false	otherwise

Implements OGF::Callable.

method()

MetaMethod * OGF::Request::method ( ) const

inline

Gets the method to be invoked.

Returns

a pointer to the MetaMethod that corresponds to the method to be invoked.
