Direct Known Subclasses:

GridCell, PropertyDisplay

public abstract class AbstractPropertyOutput
extends java.lang.Object

Base class for components that output a property value using a PropertyModel. There's a relationship between such a component and its container, as the container may provide messages in its message catalog needed by the Blocks that render the values. In addition, the component may be passed Block parameters that are output overrides for specified properties. Subclasses will implement a beginRender() method that invokes renderPropertyValue(MarkupWriter, String).
