Customizing slots

In the previous examples, we used the @JIPipeInputSlot and @JIPipeOutputSlot annotations with autoCreate = true to automatically configure the slots.

This is not sufficient for more complicated algorithms that require

• Restricting the number of slots
• Restricting the allowed data types
• Users to add more slots or remove existing ones

A custom JIPipeSlotConfiguration can be used to implement such more advanced behaviors.

For many cases, the default implementation JIPipeMutableSlotConfiguration is sufficient.

The slot configuration can be overriden during instantiation of the algorithm:

public MyAlgorithm(JIPipeNodeInfo info) {
    super(info, JIPipeMutableSlotConfiguration.builder()
    .addInputSlot("Input", ImagePlusData.class)
    .restrictOutputTo(ImagePlusData.class)
    .build());
}
