JavaClass

A JavaScript reference to a Java class.

Core object
Implemented in	JavaScript 1.1, NES 2.0

Created by

A reference to the class name used with the Packages object:

Packages.JavaClass

where JavaClass is the fully-specified name of the object's Java class. The LiveConnect java, sun, and netscape objects provide shortcuts for commonly used Java packages and also create JavaClass objects.

Description

A JavaClass object is a reference to one of the classes in a Java package, such as netscape.javascript.JSObject. A JavaPackage object is a reference to a Java package, such as netscape.javascript. In JavaScript, the JavaPackage and JavaClass hierarchy reflect the Java package and class hierarchy.

You must create a wrapper around an instance of java.lang.Class before you pass it as a parameter to a Java method--JavaClass objects are not automatically converted to instances of java.lang.Class.

Property Summary

The properties of a JavaClass object are the static fields of the Java class.

Method Summary

The methods of a JavaClass object are the static methods of the Java class.

Examples

In the following example, x is a JavaClass object referring to java.awt.Font. Because BOLD is a static field in the Font class, it is also a property of the JavaClass object.

x = java.awt.Font
myFont = x("helv",x.BOLD,10) // creates a Font object

The previous example omits the Packages keyword and uses the java synonym because the Font class is in the java package.
