MATLAB: Code completion/hints for Java methods in MATLAB editor

autocompletioneditorhintsjava

Hi,

I'm a Java developer that supports MATLAB developers with Java libraries/GUIs that they can call from MATLAB. Currently, I need to send the MATLAB developer the JavaDoc for them to determine the available methods and associated method signature (arguments and types). This is because it doesn't appear that the MATLAB editor shows hints for Java classes or we don't know how to turn that feature on.

I imagine I could help them write a simple MATLAB function that prints all the method signatures of a given class using Java Reflection, but it'd be much nicer if the MATLAB editor did that in a context sensitive way. Is there a way to configure the MATLAB editor to show the methods and signatures of a given Java class based on the editor context?

I'm sure I'm not the first one to ask this, but I spent some time searching I didn't find anything that popped out at me.

Thanks,

Rob

Hi,

not that I know off, but you can use the methodsview function for that:

>> a = java.lang.String('hallo')
a =
hallo
>> methodsview(a)
>> methodsview('java.lang.String')

I am not sure what you mean by a simple signal in Java. But here is a simple example:

--> Java Code

import java.lang.*;
public class SimpleJavaSignal
{
    public int returnSignal()
    {
        return 56;
    }
}

You compile this into SimpleJavaSignal.class.

Use

javaaddpath('directory where the .class file resides')
a = SimpleJavaSignal(); % Creates an object of the java class
methodsview(a); % displays all the methods
a.returnSignal() % calls the Java method returnSignal

MATLAB: How to pass a javaArray of Doubles to a method that takes double[] arguments from MATLAB

java.lang.Double is an object wrapper around the Java double builtin data type. Arrays of java.lang.Doubles cannot be used as arguments to methods that expect double[].

To call methods with these signatures, use a MATLAB array of doubles:

ma = [11 12];
b = mySum.sum(ma)

This returns the expected result:

 b =
     23

Note that the argument is converted automatically, as the array "ma" above, is passed by value.
