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 callingInstall4JPropertyDescriptor.setParentProperty(String)
on their property descriptors. If you register an implementation of this interface withInstall4JPropertyDescriptor.setVisibilityDiscriminator(VisibilityDiscriminator)
, each time the value of the parent property changes, a callback will be made toisVisible(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
.
