Constructor Detail

### CoordDoubleString

    public CoordDoubleString(int tuplecount,
                             int tuplesize,
                             BinaryFile input)
                      throws FormatException

  Construct a CoordDoubleString from a file input

Parameters:
  `tuplecount` - the number of tuples to read from the input stream
  `tuplesize` - the number of doubles in the tuple
  `input` - the input stream to read everything from
Throws:
  `FormatException` - if we have IO errors or premature end-of-file

Method Detail
