allocate

static CleanableDirectBuffer allocate(int capacity)

buffer

public java.nio.ByteBuffer buffer()

Description copied from interface: CleanableDirectBuffer

Get the buffer instance.

Note: the buffer must not be accessed after the CleanableDirectBuffer.clean() method has been called.

Specified by:

buffer in interface CleanableDirectBuffer

Returns:

The ByteBuffer instance.

clean

public void clean()

Description copied from interface: CleanableDirectBuffer

Deallocate the buffer. This method can only be called once per instance, and all usages of the buffer must have ceased before this method is called, and the buffer must not be accessed again after this method has been called.

Specified by:

clean in interface CleanableDirectBuffer

hasMemoryAddress

public boolean hasMemoryAddress()

Specified by:

hasMemoryAddress in interface CleanableDirectBuffer

Returns:

true if the native memory address is available, otherwise false.

memoryAddress

public long memoryAddress()

Description copied from interface: CleanableDirectBuffer

Get the native memory address, but only if CleanableDirectBuffer.hasMemoryAddress() returns true, otherwise this may return an unspecified value or throw an exception.

Specified by:

memoryAddress in interface CleanableDirectBuffer

Returns:

The native memory address of this buffer, if available.
