Detailed Description

The Dot Operator allows access to members of composite types, such as in frame.pos.x .

This is used if a dot was parsed on a value type. It is different by semantics of the UnaryOp because the dot is parsed as a binary operator but actually is a unary ( hard to explain, look at the code...)

Definition at line 103 of file Operators.hpp.

Member Function Documentation

virtual DataSourceBase* RTT::detail::DotOp::build	(	const std::string &	member,
		DataSourceBase *	a
	)			[pure virtual]

If op is the operator you are responsible for, and if the argument DataSource is of the correct type, then return an appropriate DataSource.

( i.e. a DataSource that will apply a certain operation on the value it gets from its argument DataSource, and will return that value ). Otherwise, return 0.

Implemented in RTT::detail::DotOperator< function >.
