Detailed Description

A MemoryAllocator implementation based on a growable slice of VirtualMemory.

Member Function Documentation

virtual void * SC::VirtualAllocator::allocateImpl	(	const void *	owner,
		size_t	numBytes,
		size_t	alignment )

overrideprotectedvirtual

Allocate virtual function to be reimplemented.

Parameters

owner	Can be `nullptr` or an address belonging to a previous allocation of this allocator
numBytes	How many bytes to allocate
alignment	Alignment of the allocation

Returns: false if the passed not-null owner doesn't belong to this allocator or the allocation itself fails

Reimplemented from SC::FixedAllocator.

virtual void * SC::VirtualAllocator::reallocateImpl	(	void *	memory,
		size_t	numBytes )

overrideprotectedvirtual

Re-allocate virtual function to be reimplemented.

Reimplemented from SC::FixedAllocator.
