All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>, Bean, DynamicBean

public class MapBean
extends HashMap<String,Object>
implements DynamicBean

Implementation of a fully dynamic Bean based on an exposed Map.

Properties are dynamic, and can be added and removed at will from the map.

This class extends HashMap, allowing it to be used wherever a map is. See FlexiBean for a map-like bean implementation that is more controlled.

Constructor Detail

MapBean

public MapBean()

Creates an instance.

Method Detail

meta

public static DynamicMetaBean meta()

Creates a standalone meta-bean.

This creates a new instance each time in line with dynamic bean principles.

Returns:

the meta-bean, not null

metaBean

public DynamicMetaBean metaBean()

Description copied from interface: DynamicBean

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

Specified by:

metaBean in interface Bean

Specified by:

metaBean in interface DynamicBean

Returns:

the meta-bean, not null

property

public Property<Object> property(String name)

Description copied from interface: DynamicBean

Gets a property by name.

This will not throw an exception if the property name does not exist. Whether a property is immediately created or not is implementation dependent.

Specified by:

property in interface Bean

Specified by:

property in interface DynamicBean

Parameters:

name - the property name to retrieve, not null

Returns:

the property, not null

propertyNames

public Set<String> propertyNames()

Description copied from interface: Bean

Gets the set of property names.

Each bean consists of a known set of properties. This method returns the known property names.

Specified by:

propertyNames in interface Bean

Returns:

the unmodifiable set of property names, not null

propertyDefine

public void propertyDefine(String propertyName,
                           Class<?> propertyType)

Description copied from interface: DynamicBean

Adds a property to those allowed to be stored in the bean.

Some implementations will automatically add properties, in which case this method will have no effect.

Specified by:

propertyDefine in interface DynamicBean

Parameters:

propertyName - the property name to check, not empty, not null

propertyType - the property type, not null

propertyRemove

public void propertyRemove(String propertyName)

Description copied from interface: DynamicBean

Removes a property by name.

Specified by:

propertyRemove in interface DynamicBean

Parameters:

propertyName - the property name to remove, null ignored

clone

public MapBean clone()

Overrides:

clone in class HashMap<String,Object>

toString

public String toString()

Returns a string that summarises the bean.

The string contains the class name and properties.

Overrides:

toString in class AbstractMap<String,Object>

Returns:

a summary string, not null
