DefaultHostMemoryAllocator#

public class DefaultHostMemoryAllocator implements HostMemoryAllocator #

The default HostMemoryAllocator, which uses pinned memory when requested and available and falls back to off-heap memory.

The process-wide default allocator can be changed with set(HostMemoryAllocator).

Method Summary

`allocate(long bytes)`	Allocate memory, but be sure to close the returned buffer to avoid memory leaks.
`allocate(long bytes, boolean preferPinned)`	Allocate memory, but be sure to close the returned buffer to avoid memory leaks.
`get()`	Retrieve current host memory allocator used by default if not passed directly to API.
`set(HostMemoryAllocator hostMemoryAllocator)`	Sets a new default host memory allocator implementation by default.

Methods

public HostMemoryBuffer allocate(long bytes, boolean preferPinned)#

Allocate memory, but be sure to close the returned buffer to avoid memory leaks.

Parameters:

bytes – size in bytes to allocate
preferPinned – If set to true, the pinned memory pool will be used if possible with a fallback to off-heap memory. If set to false, the allocation will always be from off-heap memory.

Returns:

the newly created buffer

public HostMemoryBuffer allocate(long bytes)#

Allocate memory, but be sure to close the returned buffer to avoid memory leaks.

Pinned memory for allocations preference is up to the implementor

Static Methods

Retrieve current host memory allocator used by default if not passed directly to API.

public static void set(HostMemoryAllocator hostMemoryAllocator)#

Sets a new default host memory allocator implementation by default.
