Class FileChannelDecorator
Object
AbstractInterruptibleChannel
FileChannel
FileChannelDecorator
- All Implemented Interfaces:
- Closeable, ByteChannel, Channel, GatheringByteChannel, InterruptibleChannel, ReadableByteChannel, ScatteringByteChannel, WritableByteChannel
public class FileChannelDecorator
- extends FileChannel
- implements ReadableByteChannel
A FileChannel that delegates all calls to the underlying FileChannel but for
implCloseChannel()
it also calls ShapefileFiles.unlock method to
release the lock on the URL.
