All Known Implementing Classes:

BasicBean, DirectBean, FlexiBean, MapBean

public interface Bean

A bean consisting of a set of properties.

The implementation may be any class, but is typically a standard JavaBean with get/set methods. Alternate implementations might store the properties in another data structure such as a map.

metaBean

MetaBean metaBean()

Gets the meta-bean representing the parts of the bean that are common across all instances, such as the set of meta-properties.

Returns:

the meta-bean, not null

property

<R> Property<R> property(String propertyName)

Gets a property by name.

The base interface throws an exception if the name is not recognised. By contrast, the DynamicBean subinterface creates the property on demand.

Type Parameters:

R - the property type, optional, enabling auto-casting

Parameters:

propertyName - the property name to retrieve, not null

Returns:

the property, not null

Throws:

NoSuchElementException - if the property name is invalid

propertyNames

Set<String> propertyNames()

Gets the set of property names.

Returns:

the unmodifiable map of property objects, not null

clone

Bean clone()

Clones this bean, returning an independent copy.

Implementations should covariantly return their own type.

Returns:

the clone, not null
