jinvoke

Parameters

object

A mlist typed _JObj or _JClass or a Scilab variable

methodName

A string giving the method name

arg_i

A Scilab variable as method argument

Description

Invoke the Java method (static or not) called methodName of the given object. The result is returned as a mlist typed _JObj.

The polymorphism is handled in using Java Reflection and the autoboxing is handled too so ArrayList.add(1.234) or ArrayList.add("Hello") are allowed. If it exists a method Foo.bar(int), it is possible to write Foo.bar(123) even if 123 is a Scilab double but Foo.bar(double), if it exists, will be chosen.

Examples

jimport java.lang.System;
jimport java.awt.Color;
jimport java.lang.String;

// Non-static methods
jinvoke("Hello World !!", "length");
str = String.new("Hello");
jinvoke(str,"substring",1, 4)

// Static method
T = jinvoke(System, "getProperty", "java.version");

// Combine
c = jinvoke(Color, "decode", "123456");
cb = jinvoke(c, "brighter");

jcode = jinvoke(cb, "getRGB");

jremove System Color T c cb jcode;
