jimport

Parameters

className

A string giving the class name

isAClassReturned

A boolean to indicate if a class object must be returned

Description

The class must be in the classpath (to add a package or a directory in the Java classpath, just use javaclasspath).

When jimport("java.lang.String"), a mlist named String is created on the Scilab stack. The created mlist has a type equal to _JClass and can be used to instantiate new objects in using something like str = String.new("A Scilab String");. It is possible to call the static methods (if exist) of the class

jimport java.lang.Math;
x=Math.random();
disp(x);
jremove Math x;

To avoid confusion with already existing Scilab variables, the second argument isAClassReturned can be used

String = "Hello";
foo = jimport("java.lang.String", %f);
obj = foo.new("A string...")
jremove(obj);

A class can be reloaded if it is allowed by the function jallowReloadClass.

Examples

jimport javax.swing.JFrame;
jimport javax.swing.JLabel;

jframe = JFrame.new("Hello World !! Window");
jlabel = JLabel.new("A JLabel containing ""Hello Wolrd""");
cp = jframe.getContentPane();
cp.add(jlabel);
jframe.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
jframe.pack();
jframe.setVisible(%t);
jremove jlabel cp jframe;
