Class MatOutputStreamWriter

java.lang.Object
  ch.javasoft.jsmat.MatWriter<DataOutputStream>
      ch.javasoft.jsmat.MatOutputStreamWriter

public class MatOutputStreamWriter
extends MatWriter<DataOutputStream>

The MatOutputStreamWriter writes a .mat file structure to a given OutputStream.

Note: Writing a file is more memory efficient with the MatFileWriter. This implementation uses byte array buffers to compute the block sizes before writing to the real output stream.

Constructor Detail

MatOutputStreamWriter

public MatOutputStreamWriter(OutputStream out)
                      throws IOException

Constructor, writing data to the given output stream

Parameters:

out - the output stream to write to

Throws:

IOException - if any io exception occurs

Method Detail

initDataOutput

protected void initDataOutput(DataOutputStream dataOutput)
                       throws IOException

No operation is performed here (no initialization needed)

Specified by:

initDataOutput in class MatWriter<DataOutputStream>

Parameters:

dataOutput - the data output object to initialize

Throws:

IOException

createVariableWriter

protected VariableWriter createVariableWriter()
                                       throws IOException

Description copied from class: MatWriter

Creates a writer for variable output. Variables are written compressed, which needs some initialization executed when VariableWriter.open() is called. The same structures must be released again after writing the variable data, which is done in VariableWriter.close().

Specified by:

createVariableWriter in class MatWriter<DataOutputStream>

Throws:

IOException

close

public void close()
           throws IOException

Closes the underlying output stream

Specified by:

close in class MatWriter<DataOutputStream>

Throws:

IOException - if any io exception occurs
