Interface VisibilityDiscriminator

public interface VisibilityDiscriminator
Interface for controlling the visibility of child properties based on the value of the parent property. This applies to properties that have been arranged in a tree-like structure by calling Install4JPropertyDescriptor.setParentProperty(String) on their property descriptors. If you register an implementation of this interface with Install4JPropertyDescriptor.setVisibilityDiscriminator(VisibilityDiscriminator), each time the value of the parent property changes, a callback will be made to isVisible(Bean, Object) in order to decide whether the child property should be visible or not.

For boolean parent properties, if you not register a visibility discriminator, the children will be hidden if the user selection of the parent property is false.
