Class XAttributeMapLazyImpl<T extends XAttributeMap>

  • All Implemented Interfaces:
    java.lang.Cloneable, java.util.Map<java.lang.String,​XAttribute>, XAttributeMap
    public class XAttributeMapLazyImpl<T extends XAttributeMap>
extends java.lang.Object
implements XAttributeMap
    Lazy implementation of the XAttributeMap interface. This implementation serves as a proxy for an XAttributeMapImpl instance, which is initially not present. Once the attribute map is to be filled with values, the true backing XAttributeMapImpl instance will be created on the fly, and used for storing and accessing data transparently. This lazy instantiation prevents lots of initializations of real attribute maps, since a large amount of attributes do not have any meta-attributes. This class is a generic, and can be parametrized with the actual implementation for the backing storage, which will then be instantiated on demand. Note that you will also have to pass the Class object of this implementation to the constructor, since this is required for instantiation (by Java).
