What Is a Project?

A Java Builder project contains information about the files and settings

needed by MATLAB Builder for Java to create a deployable Java component.

A project specifies information about classes and methods, including the

MATLAB functions to be included.

• “Na ming Conventions” on page 2-3

Classes and Methods

Java Builder transform s MATLAB functions that are specified in the

component’s project to methods belonging to a Java class.

When creating a component, you must pro vide one or more class names as

well as a component name. The class name denotes the name o f the class

that encapsulates MATLAB functions.

To access the features and operations provided by the MATLAB functions,

instantiate the Java class generated by Java Builder, and then call the

methods that encapsulate the MATLAB functions.

Note When you add file s to a project, you do not have to add any M-files for

functions that are called by the functions that you add. When Java Builder

builds a com ponent, it automatically includes any M functions called by the

functions that you explicitly specify for the component. See “Spectral Analysis

Example” on page 5-8 for a sample application that illustrates this feature.

Naming Conventions

Typically you sh ould s pecify names for components and classes th at will be

clear to programmers who use your components. For exam ple, if you are

encapsulating many MATLAB functions, it helps to determine a scheme of

function categories and to create a separate class for each category. Also, the

name of each class should be descriptive of what the class does.
