Detailed Description

The base class for a property that represents a function.

Member Function Documentation

Execute()

virtual void ezAbstractFunctionProperty::Execute ( void *  pInstance, ezArrayPtr< ezVariant >  arguments, ezVariant &  out_returnValue  ) const

pure virtual

Calls the function. Provide the instance on which the function is supposed to be called.

arguments must be the size of GetArgumentCount, the following rules apply for both arguments and return value: Any standard type must be provided by value, even if it is a pointer to one. Types must match exactly, no ConvertTo is called. enum and bitflags are supported if ezEnum / ezBitflags is used, value must be provided as ezInt64. Out values (&, *) are written back to the variant they were read from. Any class is provided by pointer, regardless of whether it is a pointer or not. The returnValue must only be valid if the return value is a ref or by value class. In that case returnValue must be a ptr to a valid class instance of the returned type. An invalid variant is equal to a nullptr, except for if the argument is of type ezVariant, in which case it is impossible to pass along a nullptr.

Implemented in ezPhantomFunctionProperty, ezConstructorFunctionProperty< CLASS, Args >, ezScriptCoroutineFunctionProperty, ezFunctionProperty< R(*)(Args...)>, ezFunctionProperty< R(CLASS::*)(Args...) const >, ezFunctionProperty< R(CLASS::*)(Args...)>, ezAngelScriptFunctionProperty, and ezVisualScriptFunctionProperty.
