Extended Java

Version

The previous implementations are relatively simple in that they use a

minimal number of computation classes. Let’s extend this to cover

additional functionality that will often be needed for a new node:

• Add a property dialog

• Validate whether required properties are specified

• Provide a custom viewer

• Use lower-level buffer manipulation routines

In this example we will write all of the code in Java. If we prefer to

use C++, we still need to use Java for the GUI classes. We can use

C++ for the computation as described in the previous example.

This example will use a single input and output. Multiple inputs and

outputs would require a more sophisticated dialog than the one

presented here.

Node Model The node model class defined in the file ThirdCopyNodeModel.java

will take care of launching the property dialog, launching the viewer,

and validating whether the required properties are set.
