Name
NSScriptWhoseTest — Mac OS X 10.0
Synopsis
This class is used in Cocoa’s scripting system to
represent the Boolean expression of an
NSScriptWhoseSpecifier.
NSScriptWhoseTest is an abstract class that
defines only the single method isTrue. This method
is invoked to evaluate the expression represented by the
NSScriptWhoseTest object, and returns a
BOOL. Foundation implements two concrete
subclasses of this class: NSLogicalTest and
NSSpecifierTest.
