Function Documentation

operator<<()

std::ostream & operator<<	(	std::ostream &	out,
		const SG::AuxElement &	obj )

Operator printing the payload of an xAOD object.

This function can be used to quickly get an idea about the payload held by any type of xAOD object. It prints the type and name of each auxiliary variable associated with the object. And for some simple types (primitives and some vectors of primitives) it even prints the values of these variables.

Parameters

out	The stream to write the information to
obj	The object to write the information about

Returns

The same stream object that was given to the function
