Detailed Description

How we parse: this parser works like a stack-based RPN calculator. An atomic expression pushes one internal::DataSource up the stack, a binary expression pops two DataSources, and pushes a new one, a unary pops one, and pushes one etc. This allows for the reentrancy we need..

boost::shared_ptr<base::AttributeBase> RTT::scripting::ExpressionParser::getHandle (  ) 

In case the parsed result returns a SendHandle, ask the parser to also create a handle for it.

Returns:
null pointer if no handle could be made.
