Constructor Detail

VectorUnknownPeriodReader

public VectorUnknownPeriodReader(VectorReader in,
                                 boolean makePeriodicCopy)
Creates a new periodic reader
Parameters:
in - the underlying vector reader
makePeriodicCopy - flag saying if on each period a new vector is built

VectorUnknownPeriodReader

public VectorUnknownPeriodReader(VectorReader in)
Creates a new periodic reader. Each period a new vector is built
Parameters:
in - the underlying vector reader
Method Detail

read

public double[] read()
              throws java.io.IOException
Reads a vector in stream
Specified by:
read in interface VectorReader
Throws:
java.io.IOException - if the stream is closed or if it is unable to read size doubles

size

public int size()
Returns the stream size (vector size)
Specified by:
size in interface VectorReader

period

public int period()
Returns the stream period
Specified by:
period in interface VectorReader
Following copied from interface: epfl.io.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:
java.io.IOException - if an IO error occurs
