parse()

Expression * App::ExpressionParser::parse	(	const App::DocumentObject *	owner,

	)

Parse the expression given by buffer, and use owner as the owner of the returned expression.

If the parser fails for some reason, and exception is thrown.

Parameters

owner	The DocumentObject that will own the expression.
buffer	The string buffer to parse.

Returns

A pointer to an expression.
