operator new(TUint)

TAny * operator new ( TUint aSize ) [static]

Allocates the object from the heap and then initialises its contents to binary zeroes.

Parameters

TUint aSize The size of the derived class. This parameter is specified implicitly by C++ in all circumstances in which a derived class is allocated.

operator new(TUint, TLeave)

TAny * operator new ( TUint aSize,
TLeave
) [static]

Allocates the object from the heap and then initialises its contents to binary zeroes.

Parameters

TUint aSize The size of the derived class. This parameter is specified implicitly by C++ in all circumstances in which a derived class is allocated.
TLeave

operator new(TUint, TUint)

TAny * operator new ( TUint aSize,
TUint aExtraSize
) [static]

Allocates the object from the heap and then initialises its contents to binary zeroes.

Use of this overload is rare.

Parameters

TUint aSize The size of the derived class. This parameter is specified implicitly by C++ in all circumstances in which a derived class is allocated.
TUint aExtraSize Indicates additional size beyond the end of the base class.

operator new(TUint, RHeap *)

TAny * operator new ( TUint aSize,
RHeap * aHeap
) [static]

Parameters

TUint aSize
RHeap * aHeap
