Package org.geotools.data.shapefile.files

Class FileChannelDecorator

  • All Implemented Interfaces:
    Closeable, AutoCloseable, ByteChannel, Channel, GatheringByteChannel, InterruptibleChannel, ReadableByteChannel, ScatteringByteChannel, SeekableByteChannel, 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.
