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.

### ExpandedNameTable

  Create an expanded name table.

Method Detail

### getExpandedTypeID

    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.

### 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 java.lang.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 java.lang.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:
