Enumerator
ALLOC	Allocates memory for an object.
DESTRUCT_AND_RELEASE	Destructs the object to which dst points and releases the memory.
COPY	Copies the object from src to dst and returns the size on success (0 on failure).
MOVE_AND_DESTRUCT	Moves the object from src to dst and returns the size (only used for internal storage, cannot fail).

◆  DelegateBase() [1/5]

DelegateBase

(

)

◆  ~DelegateBase()

◆  DelegateBase() [2/5]

Constructs a delegate using object, stub and utility callback pointer.

Template Parameters

STUBPTR

The stub pointer type.

参数

[in]	objectPtr	Self pointer of the object. Might be nullptr if the method has been inlined into the stub.
[in]	stubPtr	Stub method pointer (which forward the call to the callable).
[in]	callback	Utility callback which handles copy, move and destruction of the object. Nullptr for a static function.

◆  DelegateBase() [3/5]

Assign when T is not a Delegate , but a function pointer, ptmf or a PTMFWrapper<OBJECT*, RESULT (OBJECT::*)(ARGS...)>.

◆  DelegateBase() [4/5]

◆  DelegateBase() [5/5]

成员函数文档编制

◆  MAXON_ENUM_ORDERED_LIST_CLASS()

◆  MAXON_OPERATOR_MOVE_ASSIGNMENT()

◆  Reset()

◆  CopyFrom() [1/3]

参数

[in]

src

Source delegate.

返回

OK on success.

◆  CopyFrom() [2/3]

Assign when T is not a Delegate , but a function pointer, ptmf or a PTMFWrapper<OBJECT*, RESULT (OBJECT::*)(ARGS...)>.

◆  CopyFrom() [3/3]

Copies or moves #object into the Delegate and sets #stub as the handler for delegate calls. #stub will receive a pointer to the object held by the Delegate in its first parameter.

参数

[in]	object	The object to move or copy.
[in]	stub	The call handler.

返回

OK on success.

◆  IsEmpty()

◆  IsPopulated()

◆  IsStaticFunctionPointer()

◆  GetStaticFunctionPointer()

◆  GetStubPointer()

◆  GetReferenceUtilityStub() [1/2]

◆  GetReferenceUtilityStub() [2/2]

◆  PTMFUtilityStub()

A dummy stub for inlined PTMF which does nothing.

◆  UtilityStub()

Destructs, copies or moves an object with operator ()().

◆  ReferenceUtilityStub()

Destructs, copies or moves a reference with operator ()(). This treats _storage[0] as if it was not just a pointer, but a REFERENCE.
