public final class Class
extends totalcross.lang.Object

This class contains utility methods that are used to load classes by name and get information about their fields and methods.

IMPORTANT: the totalcross.lang package is the java.lang that will be used in the device. You CANNOT use nor import totalcross.lang package in desktop. When tc.Deploy is called, all references to java.lang are replaced by totalcross.lang automatically. Given this, you must use only the classes and methods that exists BOTH in java.lang and totalcross.lang. For example, you can't use totalcross.lang.ClassLoader because there are no totalcross.lang.ClassLoader. Another example, you can't use totalcross.lang.String.indexOfIgnoreCase because there are no totalcross.lang.String.indexOfIgnoreCase method. Trying to use a class or method from the java.lang package that has no correspondence with totalcross.lang will make the tc.Deploy program to abort, informing where the problem occured. A good idea is to always refer to this javadoc to know what is and what isn't available.

forName

public static Class forName(String className)
                     throws ClassNotFoundException

The TotalCross deployer can find classes that are instantiated using Class.forName if, and only if, they are totalcross.lang.String constants. If you build the className dynamically, then you must include the file passing it to the tc.Deploy application (the deployer will warn you about that).

Throws:

ClassNotFoundException

newInstance

public Object newInstance()
                   throws totalcross.lang.InstantiationException,
                          totalcross.lang.IllegalAccessException

Creates a new instance of this class.

Throws:

InstantiationException - If you try to instantiate an interface, abstract class or array

IllegalAccessException - If you try to instantiate a private class

totalcross.lang.InstantiationException

totalcross.lang.IllegalAccessException

isInstance

public boolean isInstance(Object obj)

Returns true if the given object is an instance of this class.

getName
