      • LazyMetaPropertyMap

        public LazyMetaPropertyMap​(java.lang.Object o)
        Constructs the map
        Parameters:
        o - The object to inspect

    • Method Detail

      • size

        public int size()
        Specified by:
        size in interface java.util.Map
        See Also:
        Map.size()

      • isEmpty

        public boolean isEmpty()
        Specified by:
        isEmpty in interface java.util.Map
        See Also:
        Map.isEmpty()

      • containsKey

        public boolean containsKey​(java.lang.Object propertyName)
        Specified by:
        containsKey in interface java.util.Map
        See Also:
        Map.containsKey(java.lang.Object)

      • containsValue

        public boolean containsValue​(java.lang.Object o)
        Checks whether the specified value is contained within the Map. Note that because this implementation lazily initialises property values the behaviour may not be consistent with the actual values of the contained object unless they have already been initialised by calling get(Object)
        Specified by:
        containsValue in interface java.util.Map
        See Also:
        Map.containsValue(Object)

        Specified by:
        get in interface java.util.Map
        Parameters:
        propertyName - The name of the property
        Returns:
