readBytes

public int readBytes(byte[] buf,
                     int start,
                     int count)
              throws IOException

Description copied from class: Stream

Reads bytes from the stream. Returns the number of bytes actually read or -1 if the end of the stream was reached. (if applicable to the stream)

Overrides:

readBytes in class CompressedStream4D

Parameters:

buf - the byte array to read data into

start - the start position in the array

count - the number of bytes to read

Throws:

IOException

writeBytes

public int writeBytes(byte[] buf,
                      int start,
                      int count)
               throws IOException

Description copied from class: Stream

Writes bytes to the stream. Returns the number of bytes actually written or throws an IOException if an error prevented the write operation from occurring.

Overrides:

writeBytes in class CompressedStream4D

Parameters:

buf - the byte array to write data from

start - the start position in the byte array

count - the number of bytes to write

Returns:

the number of bytes actually written

Throws:

IOException

close

public void close()
           throws IOException

Closes this I/O connection, releasing any associated resources. Once closed a connection is no longer valid.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class CompressedStream4D

Throws:

IOException - If an I/O error occurs.

finalize

protected void finalize()

Overrides:

finalize in class CompressedStream4D
