Specified by:
size in interface VectorReader

period

public int period()
Returns the stream period

period in interface VectorReader
Returns:
0 if the stream is not periodic

close

public void close()
           throws java.io.IOException
Closes the stream
Specified by:
close in interface VectorReader
Throws:
