Name
getClass( ): return the JavaClass of a JavaObject â LiveConnect
Synopsis
getClass(javaobj
)
Arguments
-
javaobj
A JavaObject object.
Returns
The JavaClass object of
javaobj
.
Description
getClass( )
is a function
that takes a JavaObject object (javaobj
)
as an argument. It returns the JavaClass object of that JavaObject.
That is, it returns the JavaClass object that represents the Java
class of the Java object represented by the specified
JavaObject.
Usage
Donât confuse the JavaScript getClass( )
function with the
getClass method of all Java objects. Similarly,
donât confuse the JavaScript JavaClass object with the Java
java.lang.Class class.
Consider the Java Rectangle object created with the following line:
var r = new java.awt.Rectangle( );
r
is a JavaScript variable
that holds a JavaObject object. Calling the JavaScript function
getClass( )
returns a JavaClass
object that represents the java.awt.Rectangle
class:
var c = getClass(r);
You can see this by comparing this JavaClass object to
java.awt.Rectangle
:
if (c == java.awt.Rectangle) ...
The Java getClass( )
method
is invoked differently and performs an entirely different
function:
c = r.getClass( );
After executing this line of code, c
is a JavaObject that represents a
java.lang.Class
object. This
java.lang.Class
object is a Java
object that is a Java representation of the
java.awt.Rectangle class. See your Java
documentation for details on what you can do with the
java.lang.Class class.
To summarize, you can see that the following expression ...
