Method Detail

allocate

public static DirectBytes allocate(long size)

Allocates a direct ByteBuffer based byte array.

When the array is constructed, DirectMemoryAllocator will be used to allocate count bytes of off-heap memory. Memory is accessed by the buffer directly via Unsafe.

Parameters:

size - The count of the buffer to allocate (in bytes).

Returns:

The native buffer.

Throws:

IllegalArgumentException - If count is greater than the maximum allowed count for a ByteBuffer - Integer.MAX_VALUE - 5

copy

public DirectBytes copy()

Copies the bytes to a new byte array.

Returns:

A new HeapBytes instance backed by a copy of this instance's array.
