geomss.geom.reader.iges.Constants

public class Constants
extends java.lang.Object

The Constants class is a holding area for any "global" variables that are needed for multiple classes. Also included are several utility methods that may be used any place that needs them. It is hoped that there will be no hard-coded values anywhere.

Method Detail

initGlobals

public static void initGlobals(GlobalSection g)

Set up globals from GlobalSection

Parameters:

g - Global Section object

myReadLine

public static java.lang.String myReadLine(java.io.RandomAccessFile in)
                                   throws java.io.IOException

Reads in a line of text, 80 characters, ignoring any EOL chars

Parameters:

in - input file

Returns:

the single text line of input

Throws:

java.io.IOException - if end of file is reached, or other generic file I/O error.

toInt

public static int toInt(java.lang.String s)

Converts the string to an integer. This method can handle "integers" that are technically real, such as 1.000D+001. A zero length string results in the value 0 being returned.

Parameters:

s - the string to be parsed. Assumed to be trimmed of whitespace.

Returns:

resulting integer

toDouble

public static double toDouble(java.lang.String s)

Converts the string to an double. This method can handle IGES floats of single ("1.00e+010") or double ("1.00d+010") precision. A zero length string results in the value 0.0 being returned.

Parameters:

s - the string to be parsed. Assumed to be trimmed of whitespace.

Returns:

resulting double value

dist

public static double dist(double x1,
                          double y1,
                          double x2,
                          double y2)

2D distance. Distance between two points in a plane.

Parameters:

x1 - abscissa of first point

y1 - ordinate of first point

x2 - abscissa of 2nd point

y2 - ordinate of second point

Returns:

2D distance between the points

dist

public static double dist(double x1,
                          double y1,
                          double z1,

3D distance. Distance between two points in space.

Parameters:

x1 - X-coordinate of

y1 - Y-coordinate of

z1 - Z-coordinate of first point

x2 - X-coordinate of second point
