public class ExpandedNameTable

extends Object

This is a default implementation of a table that manages mappings from expanded names to expandedNameIDs. %REVIEW% Note that this is not really a separate table, or a separate pool. Instead, it's an access method build on top of the existing pools, using three pieces of information: the index numbers for a node's namespaceURI, localName, and node type, which are combined to yield a composite index number. %TBD% startup sequence -- how this gets access to the appropriate string pools in the DTMDocument/stylesheet.

Constructor Detail

ExpandedNameTable

public ExpandedNameTable()

Create an expanded name table that uses private string pool lookup.

ExpandedNameTable

public ExpandedNameTable(DTMStringPool locNamesPool,
                         DTMStringPool namespaceNames)

Constructor ExpandedNameTable

Parameters:

locNamesPool - Local element names lookup.

namespaceNames - Namespace values lookup.

Method Detail

initExtendedTypes

private void initExtendedTypes()

Initialize the vector of extended types with the basic DOM node types.

getExpandedTypeID

public int getExpandedTypeID(String namespace,
                             String localName,
                             int type)

Given an expanded name, 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 -

localName -

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.
