public void flush()
           throws ReadOnlyException,
                  IllegalStateException,
                  WrappedIOException

Description copied from interface: DataSink

Flush changes made to the sink to the underlying storage. This is optional to implement, but read only sinks should always throw ReadOnlyException.

Specified by:

flush in interface DataSink

Throws:

ReadOnlyException - If the sink is opened read only.

IllegalStateException - If the sink is closed.

WrappedIOException - On I/O errors.

write

public void write(byte[] barr)
           throws ReadOnlyException,
                  IllegalStateException,
                  WrappedIOException

write in interface DataSink

Parameters:

barr - The array to write.

Throws:

ReadOnlyException - If the sink is opened read only.

IllegalStateException - If the sink is closed.

WrappedIOException - On I/O errors.

write

public void write(byte[] barr,
                  int off,
                  int len)
           throws ReadOnlyException,
                  IllegalStateException,
                  WrappedIOException

Description copied from interface: DataSink

Write len bytes from the array, starting at the offset off to this sink.

Specified by:

write in interface DataSink

Parameters:

barr - The byte array.

off - The starting offset in the array.

len - The number of bytes to write.

Throws:

ReadOnlyException - If the sink is opened read only.

IllegalStateException - If the sink file is closed.

WrappedIOException - On I/O errors.

write

public void write(int b)
           throws ReadOnlyException,
                  IllegalStateException,
                  WrappedIOException

write in interface DataSink

Parameters:

b - The byte to write.

Throws:

ReadOnlyException - If the sink is opened read only.

IllegalStateException - If the random access file is closed.

WrappedIOException - On I/O errors.

close

public void close()
           throws WrappedIOException
