Constructor Detail

MapMetaObject

public MapMetaObject(TypedMap map,
                     MetaClass superClass,
                     MetaKit metaKit)

Creates a MetaObject implementat that wraps the specified map and creates a meta-class using the TypedMap's property info. The created meta-class will use the specified superClass as its superClass.

MapMetaObject

public MapMetaObject(java.util.Map map,
                     MetaClass metaClass,
                     MetaKit metaKit)

Creates a MetaObject implementation that wraps the specified map and provides access consistent with the specified meta-class. Any default values in the specified meta-class will be applied to the resulting meta-object.

MapMetaObject

public MapMetaObject(java.util.Map map,
                     MetaClass metaClass,
                     MetaKit metaKit,
                     boolean applyDefaults)

Creates a MetaObject implementation that wraps the specified map and provides access consistent with the specified meta-class.

MapMetaObject

public MapMetaObject(TypedMap map,
                     MetaKit metaKit)

Creates a MetaObject implementat that wraps the specified map and creates a meta-class using the TypedMap's property info. The generated MetaClass will have no superclass and the root class registry will be used.

Method Detail

applyDefaults

protected void applyDefaults()

Internal method to apply default values from the PropertyInfo definitions. This is called by the various constructors. It the property value is already set in the map then we don't reset it. If the default value of the PropertyInfo is null then we also don't set it... because the property in the map is already null anyway. Note: we may actually want to expose this in the MetaKit interface.

getMap

protected java.util.Map getMap()

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

setPropertyValue

protected java.lang.Object setPropertyValue(java.lang.String name,
                                            java.lang.Object value)

Stores the property in the internal map.

Specified by:

setPropertyValue in class AbstractMetaObject

getPropertyValue

protected java.lang.Object getPropertyValue(java.lang.String name)

Retrieves the property from the internal map.

Specified by:

getPropertyValue in class AbstractMetaObject

wrapPropertyValue

protected java.lang.Object wrapPropertyValue(java.lang.String name,
                                             PropertyType type,
                                             java.lang.Object value)

Overridden to wrap any nested TypedMaps.

Overrides:

wrapPropertyValue in class AbstractMetaObject

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
