Class ExpandedNameTable


  • public class ExpandedNameTable
    extends java.lang.Object
    This is a default implementation of a table that manages mappings from expanded names to expandedNameIDs. %OPT% The performance of the getExpandedTypeID() method is very important to DTM building. To get the best performance out of this class, we implement a simple hash algorithm directly into this class, instead of using the inefficient java.util.Hashtable. The code for the get and put operations are combined in getExpandedTypeID() method to share the same hash calculation code. We only need to implement the rehash() interface which is used to expand the hash table.

        public int getExpandedTypeID​(java.lang.String namespace,
                                     java.lang.String localName,
                                     int type)
        Given an expanded name represented by namespace, local name and node type, return an ID. If the expanded-name does not exist in the internal tables, the entry will be created, and the ID will be returned. Any additional nodes that are created that have this expanded name will use this ID.
        Parameters:
        namespace - The namespace
        localName - The local name
        type - The node type
        Returns:
        the expanded-name id of the node.
      • getExpandedTypeID

        public int getExpandedTypeID​(java.lang.String namespace,
                                     java.lang.String localName,
                                     int type,
                                     boolean searchOnly)
        Given an expanded name represented by namespace, local name and node type, return an ID. If the expanded-name does not exist in the internal tables, the entry will be created, and the ID will be returned. Any additional nodes that are created that have this expanded name will use this ID.

        If searchOnly is true, we will return -1 if the name is not found in the table, otherwise the name is added to the table and the expanded name id of the new entry is returned.

        Parameters:
        namespace - The namespace
        localName - The local name
        type - The node type
        searchOnly - If it is true, we will only search for the expanded name. -1 is return is the name is not found.
        Returns:
        the expanded-name id of the node.
