org.apache.shale.clay.config.beans.ComponentBean

This is the base class of most of the metadata that is used by the {@link org.apache.shale.clay.component.Clay} component to builda component subtree.

There are three sources that populate this object:
{@link org.apache.shale.clay.config.ClayXmlParser} - from XML config files
{@link org.apache.shale.clay.parser.builder.Builder} - extending classes
{@link org.apache.shale.clay.component.Clay} - shapeValidatora validator style of event method binding
