Class BeanRegistry

java.lang.Object

org.apache.juneau.BeanRegistry

public class BeanRegistry
extends Object

A lookup table for resolving bean types by name.

In a nutshell, provides a simple mapping of bean class objects to identifying names.

Class names are defined through the @Bean.typeName() annotation.

The dictionary is used by the framework in the following ways:

• If a class type cannot be inferred through reflection during parsing, then a helper "_type" is added to the serialized output using the name defined for that class in this dictionary. This helps determine the real class at parse time.
• The dictionary name is used as element names when serialized to XML.
