5 Calling Java from MATLAB

5-8

When you use the which function on methods defined by Java classes, the

function only acts on the classes currently loaded into the MATLAB working

environment. In contrast,

which always operates on MATLAB classes, whether

or not they are loaded.

Determining Which Classes Are Loaded

At any time during a MATLAB session, you can obtain a listing of all the Java

classes that are currently loaded. To do so, you use the

inmem function, in the

following form.

[M,X,J] = inmem

This function returns the list of Java classes in output argument J. (It also

returns in

M the names of all currently loaded M-files, and in X the names of all

currently loaded MEX-files.)

Here’s a sample of output from the

inmem function.

[m,x,j] = inmem

m =

'isequal'

'isunix'

'fullfile'

'filesep'

'matlabrc'

x =

'getprofl'

j =

'java.awt.Frame'

'com.mathworks.ide.desktop.MLDesktop'

Simplifying Java Class Names

Your MATLAB commands can refer to any Java class by its fully qualified

name, which includes its package name. For example, the following are fully

qualified names:

1 2 ... 173 174 175 176 177 178 179 180 181 182 183 ... 407 408
