Class ExpandedNameTable

java.lang.Object
org.apache.xml.dtm.ref.ExpandedNameTable

public class ExpandedNameTable extends 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.

    • ExpandedNameTable

      public ExpandedNameTable()
      Create an expanded name table.
  • Method Details

    • getExpandedTypeID

      public int getExpandedTypeID(String namespace, 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(String namespace, 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.
    • getExpandedTypeID

      public int getExpandedTypeID(int type)
      Given a type, return an expanded name ID.Any additional nodes that are created that have this expanded name will use this ID.
      Returns:
      the expanded-name id of the node.
    • getLocalName

      public String getLocalName(int ExpandedNameID)
      Given an expanded-name ID, return the local name part.
      Parameters:
      ExpandedNameID - an ID that represents an expanded-name.
      Returns:
      String Local name of this node, or null if the node has no name.
    • getLocalNameID

      public final int getLocalNameID(int ExpandedNameID)
      Given an expanded-name ID, return the local name ID.
      Parameters:
      ExpandedNameID - an ID that represents an expanded-name.
      Returns:
      The id of this local name.
    • getNamespace

      public String getNamespace(int ExpandedNameID)
      Given an expanded-name ID, return the namespace URI part.
      Parameters:
      ExpandedNameID - an ID that represents an expanded-name.
      Returns:
      String URI value of this node's namespace, or null if no namespace was resolved.
    • getNamespaceID

      public final int getNamespaceID(int ExpandedNameID)
      Given an expanded-name ID, return the namespace URI ID.
      Parameters:
      ExpandedNameID - an ID that represents an expanded-name.
      Returns:
      The id of this namespace.
    • getType

      public final short getType(int ExpandedNameID)
      Given an expanded-name ID, return the local name ID.
      Parameters:
      ExpandedNameID - an ID that represents an expanded-name.
      Returns:
      The id of this local name.
    • getSize

      public int getSize()
      Return the size of the ExpandedNameTable
      Returns:
      The size of the ExpandedNameTable
    • getExtendedTypes

      public ExtendedType[] getExtendedTypes()
      Return the array of extended types
      Returns:
