Example:
auto val = v.call(arg1, arg2);
Parameters
...optional arguments to the function
Returns
the return value of the function call
Exceptions
PROGRAM-ERRORthrown if the Program object holding the function has been destroyed
RUNTIME-TYPE-ERRORinvalid argument types passed to the variant

callArgs()

◆ callArgs()

auto Qore::Reflection::FunctionVariant::callArgs ( *softlist< auto >  argv)

calls the given function variant and returns the value returned by the function

Example:
auto val = v.callArgs((arg1, arg2));
Parameters
argvoptional arguments to the function
Returns
the return value of the function call
Exceptions

◆ constructor()

Qore::Reflection::FunctionVariant::constructor ( )

Throws an exception if called directly; this class can only be instantiated by builtin subclasses.

Exceptions
FUNCTIONVARIANT-CONSTRUCTOR-ERRORthis exception is thrown if this class is constructed directly (also if directly inherited by user classes)
