Class CommandLine

java.lang.Object
  jcuda.utils.CommandLine

public class CommandLine
extends java.lang.Object

Command line argument utility functions, similar to the CUTIL functions.

All command line arguments begin with '--' followed by the token. The token and value are separated by '='.
Example:
--samples=50
Arrays have the form
--model=[one.obj,two.obj,three.obj] (without whitespaces)

Method Summary

static boolean	checkCommandLineFlag(java.lang.String[] argv, java.lang.String flagName) Returns whether the given command line arguments contain an argument with the given name (the name must be given without the "--" prefix);
static float	getCommandLineArgumentFloat(java.lang.String[] argv, java.lang.String argName, float defaultValue) Returns the value of the command line argument with the given name as a float.
static int	getCommandLineArgumentInt(java.lang.String[] argv, java.lang.String argName, int defaultValue) Returns the value of the command line argument with the given name as an int.
static java.util.List<java.lang.String>	getCommandLineArgumentListString(java.lang.String[] argv, java.lang.String argName) Returns the value of the command line argument with the given name as a list of strings.
static java.lang.String	getCommandLineArgumentString(java.lang.String[] argv, java.lang.String argName) Returns the value of the command line argument with the given name as a String.
