Method Detail

allocate

public long allocate(long size,
                     long alignment,
                     VulkanSystemAllocationScope scope)

Description copied from interface: VulkanHostAllocatorCallbacksType.AllocationFunctionType

Allocate size octets of memory, aligned to alignment, of scope scope. The function must return the address of the allocated memory as an integer, or 0 if the allocation has failed. The function MUST NOT raise exceptions under any circumstances.

Specified by:

allocate in interface VulkanHostAllocatorCallbacksType.AllocationFunctionType

Parameters:

size - The size of the allocation

alignment - The alignment of the allocation

scope - The scope of the allocation

Returns:

The memory address

reallocate

public long reallocate(long address,
                       long size,
                       long alignment,
                       VulkanSystemAllocationScope scope)

Description copied from interface: VulkanHostAllocatorCallbacksType.ReallocationFunctionType

Reallocate size octets of memory, aligned to alignment, of scope scope. The function must return the address of the allocated memory as an integer, or 0 if the allocation has failed. The function MUST NOT raise exceptions under any circumstances.

Specified by:

reallocate in interface VulkanHostAllocatorCallbacksType.ReallocationFunctionType

Parameters:

address - The original memory address

size - The size of the allocation

alignment - The alignment of the allocation

scope - The scope of the allocation

Returns:

The memory address

deallocate

public void deallocate(long address)

Description copied from interface: VulkanHostAllocatorCallbacksType.DeallocationFunctionType

Deallocate memory. The function MUST NOT raise exceptions under any circumstances.

Specified by:

deallocate in interface VulkanHostAllocatorCallbacksType.DeallocationFunctionType

Parameters:

address - The original memory address

onAllocation

public void onAllocation(long size,
                         VulkanInternalAllocation type,
                         VulkanSystemAllocationScope scope)

Description copied from interface: VulkanHostAllocatorCallbacksType.InternalAllocationNotificationType

Called upon internal allocations. The function MUST NOT raise exceptions under any circumstances.

Specified by:

onAllocation in interface VulkanHostAllocatorCallbacksType.InternalAllocationNotificationType

Parameters:

size - The allocation size in bytes

type - The type of allocation

scope - The scope of the allocation

onFree

public void onFree(long size,
                   VulkanInternalAllocation type,
                   VulkanSystemAllocationScope scope)

Description copied from interface: VulkanHostAllocatorCallbacksType.InternalFreeNotificationType

Called upon internal deallocations. The function MUST NOT raise exceptions under any circumstances.

Specified by:

onFree in interface VulkanHostAllocatorCallbacksType.InternalFreeNotificationType

Parameters:

size - The allocation size in bytes

type - The type of allocation

scope - The scope of the allocation

createCallbacks

public VulkanHostAllocatorCallbacks createCallbacks()

Specified by:

createCallbacks in interface VulkanHostAllocatorType

Returns:

The methods as a set of callbacks
