public abstract class NATBoolean

extends NATByCopy

implements ATBoolean

NATBoolean is simply a container class for ambienttalk booleans. The native implementations of true and false can be accessed using the class's atValue method.

Method Detail

atValue

public static ATBoolean atValue(boolean b)

Returns the corresponding ATBoolean given a java truth value. This constructor function is to be used only when the result to be given out depends on a dynamic test, else the static fields _TRUE_ and _FALSE_ should be used instead.
