Constructor Detail

CoordFloatString

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

Construct a CoordFloatString from a file input

Parameters:

tuplecount - the number of tuples to read from the input stream

tuplesize - the number of floats 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

maxIndex

Returns:

the maximum valid tuple index

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

a pretty string of the tuple

getXasFloat

public double getXasFloat(int tuple)

Get the first value of a tuple

Parameters:

tuple - the index of the tuple

Returns:

the first value of the tuple given by tuple

getYasFloat

getZasFloat

public double getZasFloat(int tuple)

Get the third value of a tuple

Parameters:

tuple - the index of the tuple

Returns:

the third value of the tuple given by tuple

getasFloatV

public double[] getasFloatV(int tuple)

Get a tuple

Parameters:

tuple - the index of the tuple

Returns:

                         int val)

Get a value in a tuple

Parameters:

tuple - the index of the tuple

val - the index of the value

Returns:

the tuple given by tuple
