Constructor Summary

LinkNode(java.lang.String id, java.lang.String url, java.lang.String label)

Method Summary

boolean	checkId(java.lang.String id) Returns true if the id of this node equals the specified id.
void	generateXml(org.xml.sax.ContentHandler contentHandler, int depth, java.lang.String path, long userId, long[] roleIds) Generates a full, non-contextualized navigation tree up to the specified depth.
void	generateXml(org.xml.sax.ContentHandler contentHandler, Node[] activeNodePath, int pos, boolean includeOnlyActivePath, java.lang.String path, long userId, long[] roleIds)
java.lang.String	getId() Returns the id of this node, only works when isIdentifiable() returns true, otherwise throws an UnsupportedOperationException.
boolean	isExpandable() Returns true for expandable nodes, these are nodes which themselves are not a part of the generated navigation tree, but are replaced by one or more other nodes.
boolean	isIdentifiable() Returns true if this node has an ID and will generate a corresponding node in the output tree.
boolean	isVisible(long userId, long[] roleId) Returns true if this node or any of its chilren would produce a visible node in the generated navigation tree.
void	populateNodeLookupMap(java.util.Map map, java.lang.String path) Nodes representing documents should add themselves to the map, using as key a VariantKey object and as value a String object representing the navigation tree path.

LinkNode

public LinkNode(java.lang.String id,
                java.lang.String url,
                java.lang.String label)

Method Detail

checkId

public boolean checkId(java.lang.String id)

Description copied from interface: Node

Returns true if the id of this node equals the specified id.

isExpandable

public boolean isExpandable()
                     throws org.outerj.daisy.navigation.NavigationException

Description copied from interface: Node

Returns true for expandable nodes, these are nodes which themselves are not a part of the generated navigation tree, but are replaced by one or more other nodes.

Throws:

org.outerj.daisy.navigation.NavigationException

populateNodeLookupMap

public void populateNodeLookupMap(java.util.Map map,
                                  java.lang.String path)
                           throws org.outerj.daisy.repository.RepositoryException

Description copied from interface: Node

Nodes representing documents should add themselves to the map, using as key a VariantKey object and as value a String object representing the navigation tree path. A node should not add itself to the map if there is already another mapping for its document ID in the map.

Specified by:

populateNodeLookupMap in interface Node

Overrides:

populateNodeLookupMap in class AbstractParentNode

Throws:

org.outerj.daisy.repository.RepositoryException

generateXml

public void generateXml(org.xml.sax.ContentHandler contentHandler,
                        int depth,
                        java.lang.String path,
                        long userId,

                        org.xml.sax.SAXException

Description copied from interface: Node

Generates a full, non-contextualized navigation tree up to the specified depth. Specify a depth of -1 to get the full tree.

Specified by:

generateXml in interface Node

Overrides:

generateXml in class AbstractParentNode

Throws:

org.outerj.daisy.repository.RepositoryException

Specified by:

generateXml in interface Node

Overrides:

generateXml in class AbstractParentNode

Throws:

org.outerj.daisy.repository.RepositoryException

org.xml.sax.SAXException
