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

Method Details

getExpandedTypeID
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 namespacelocalName
- The local nametype
- The node type- Returns:
- the expanded-name id of the node.
-
getExpandedTypeID
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 namespacelocalName
- The local nametype
- The node typesearchOnly
- 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
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
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.
