Parameters:
zVal -
mVal -

extend

public void extend(double mVal)

Parameters:
mVal -

getByteLength

public int getByteLength()
Specified by:
getByteLength in interface Shape
Returns:
the number of bytes necessary to write this instance.

read

public int read(byte[] bytes,
                int offset)
Description copied from interface: Shape
Reads the object from a byte array.

Specified by:
read in interface Shape
offset - where to start reading
Returns:
the new offset or -1, if the type was wrong.

write

public int write(byte[] bytes,
                 int offset)
Description copied from interface: Shape
Writes the object to a byte array.

Specified by:
write in interface Shape
