Reports whether a as part of compiled Blueprint execution and object interaction.
Declaration 1 of 2
Declaration
inline bool is_a(DataHandle id,ClassId type)Reports whether a as part of compiled Blueprint execution and object interaction.
| Parameter | Type | Meaning |
|---|---|---|
id | DataHandle | Value supplied for id. Keep referenced or pointed-to data valid for the complete call. |
type | ClassId | Value supplied for type. Keep referenced or pointed-to data valid for the complete call. |
Returns: bool. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "blueprint_spawn.hpp"
// Assume these named values have been initialized with valid data:
// DataHandle id
// ClassId type
auto result = epok::bp::is_a(id, type);Trade-offs and warnings
Check the return value; `false` is part of normal control flow for many PSX resource operations.
