Constructor & Destructor Documentation

LocalContext()

ers::LocalContext::LocalContext	(	const char *	package_name,
		const char *	filename,
		int	line_number,
		const char *	function_name,
		bool	debug = false )

creates a new instance of a local context for an issue. This constructor should not be called directly, instead one should use the ERS_HERE macro.

Parameters

package_name	name of the current sw package
filename	name of the source code file
line_number	line_number in the source code
function_name	name of the current function

Definition at line 87 of file LocalContext.cpp.
