Class MapCompositeValueSupport

java.lang.Object
  org.jboss.metatype.api.values.AbstractMetaValue
      org.jboss.metatype.api.values.MapCompositeValueSupport

All Implemented Interfaces:

Serializable, Cloneable, CompositeValue, MetaValue

public class MapCompositeValueSupport
extends AbstractMetaValue
implements CompositeValue

A CompositeValue representing a Map<String,MetaValue>, where the set of allowed keys is specified by the associated MapCompositeMetaType, and where all values must be of the same MetaType. To represent a Map<String,MetaValue> where values may have different MetaTypes, use CompositeValueSupport instead.

true when the key exists, false otherwise

containsValue

public boolean containsValue(MetaValue value)

Description copied from interface: CompositeValue

Tests whether a item exists with the passed value

Specified by:

containsValue in interface CompositeValue

Parameters:

value - the value to test
