Interface ByteBufferCleanerService

public interface ByteBufferCleanerService

Service interface to perform cleaning operation on ByteBuffers.

This interface defines a contract for cleaning memory resources associated with ByteBuffers. It can be implemented by different service providers offering different mechanisms for resource cleanup.

Cleaning a ByteBuffer usually means releasing the direct memory that is typically limited and more expensive than regular heap memory. This operation can be critical in environments where lots of direct ByteBuffers are being used, like in high-performance IO or memory-mapped files.

Modifier and Type	Interface and Description
static class	ByteBufferCleanerService.Impact Enum representing the various impact levels of the cleaning operation.

Method Summary

Modifier and Type	Method and Description
void	clean(ByteBuffer buffer) Performs cleaning operation on the specified ByteBuffer.
ByteBufferCleanerService.Impact	impact() Indicates the impact level of cleaning operation.

Method Detail

impact

ByteBufferCleanerService.Impact impact()

Indicates the impact level of cleaning operation.

Returns:

the ByteBufferCleanerService.Impact of the cleaning operation on performance or resource availability.

clean

void clean(ByteBuffer buffer)

Performs cleaning operation on the specified ByteBuffer.

If the buffer is a direct ByteBuffer, this operation is expected to release any memory resources associated with it. Depending on the implementation, this method may have side effects or performance impacts, which can be queried via the impact() method.

Parameters:

buffer - the ByteBuffer to clean.
