public interface Allocator
extends java.io.Closeable
Allocator
interface is used to describe a resource
that can allocate a buffer. This is used so that memory allocation
can be implemented as a strategy allowing many different sources of
memory. Typically memory will be allocated as an array of bytes but
can be a mapped region of shared memory or a file.Modifier and Type | Method and Description |
