static _ReturnT xtd::exception::_throw_if ( const xtd::source_location &  source, _ReturnT  ret, _ExpressionT  exp, const char *  expstr  )

inlinestatic

Helper function template to test for an expression and throw an exception Throws exception if the test expression returns true.

_throw_if methods are present in many XTL exception classes. Typically, the throw_if macro will be used as in exception::throw_if to properly fill parameters

Template Parameters

_ReturnT	The return type of the function and type of the expression to evaluate. Implicitly deduced at compile time.
_ExpressionT	the type of expression tester that evaluates _ReturnT, normally a lambda.

Parameters

source	The location in source code where called.
ret	The return value of _throw_if and parameter to exp used to test for success or failure
exp	Expression used to evaluate ret. Expression is in the form of: bool (_ReturnT). The exception is thrown if this expression evaluates to true.
expstr	String value passed to the exceptions constructor when thrown

Returns

ret if no exception is thrown
