Detailed Description

template<typename TYPE>
class original::allocator< TYPE >

Default memory allocator using allocators utilities.

Template Parameters

TYPE	Type of objects to allocate

Implements standard-compliant allocator using:

• allocators::malloc for allocation
• allocators::free for de-allocation
• Placement new for construction
• Explicit destructor calls

Member Function Documentation

allocate()

template<typename TYPE >

TYPE * original::allocator< TYPE >::allocate ( u_integer  size )

overridevirtual

Allocates memory using global operator new.

Parameters

size	Number of elements to allocate

Returns

Pointer to allocated memory

Exceptions

allocateError

When memory allocation fails

Note

Returns nullptr if size is 0

Implements original::allocatorBase< TYPE, allocator >.

deallocate()

template<typename TYPE >

void original::allocator< TYPE >::deallocate ( TYPE *  ptr, u_integer  size  )

overridevirtual

Deallocates memory using global operator delete.

Parameters

ptr	Pointer to memory to free
size	Number of elements (unused in this implementation)

Implements original::allocatorBase< TYPE, allocator >.
