jimport
Import a Java class
Calling Sequence
jimport(className) cl = jimport(className, isAClassReturned)
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
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;
