| [Invoke](/engine/6000.6/script-reference/unity/burst/functionpointer1/invoke.md)       | Gets the delegate associated to this function pointer in order to call the function pointer. This delegate can be called from a Burst Job or from regular C#. If calling from regular C#, it is recommended to cache the returned delegate of this property instead of using this property every time you need to call the delegate. |
| [IsCreated](/engine/6000.6/script-reference/unity/burst/functionpointer1/iscreated.md) | Whether the function pointer is valid.                                                                                                                                                                                                                                                                                               |
| [Value](/engine/6000.6/script-reference/unity/burst/functionpointer1/value.md)         | Gets the underlying pointer.                                                                                                                                                                                                                                                                                                         |
