Method Detail

findElementWithId

public XNode findElementWithId(XNode node,
                               String id)
                        throws EvalException

Description copied from class: OutermostExprContext

Returns null because this basic implementation is not schema-aware.

Specified by:

findElementWithId in interface ExprContext

Overrides:

findElementWithId in class ExprContextImpl

Parameters:

node - used to specify the document

id - searched ID value

Returns:

element in document specified by node having specified ID if any; null otherwise

Throws:

EvalException - if a problem occurs during the search

getIdAttrNames

protected Name[] getIdAttrNames()

getIdMap

protected Map<String,IdEntry> getIdMap(XNode node)

Overrides:

getIdMap in class ExprContextImpl

findId

protected static final Element findId(Element element,
                                      Name[] idAttrNames,
                                      String id)

isElementWithId

public boolean isElementWithId(XNode node,
                               String id)
                        throws EvalException

Description copied from class: OutermostExprContext

Returns false because this basic implementation is not schema aware.

Specified by:

isElementWithId in interface ExprContext

Overrides:

isElementWithId in class ExprContextImpl

Parameters:

node - node possibly having an ID attribute

id - ID value to be matched against the possible ID attribute of node

Returns:

true if specified node has an ID attribute having specified value; false otherwise

Throws:

EvalException - if a problem occurs during the match

getDocument

public NodeIterator getDocument(String uriRef,
                                URL baseURL)
                         throws EvalException

Description copied from class: OutermostExprContext

Returns NullNodeIterator.INSTANCE because this basic implementation does not know how to load documents.

Specified by:

getDocument in interface ExprContext

Overrides:

getDocument in class ExprContextImpl

Parameters:

uriRef - specifies nodes (using a fragment) in a document

baseURL - URL possibly used to resolve relative URL in uriRef; may be null

Returns:

nodes specified by uriRef

Throws:

EvalException - if a problem occurs during the operation

                           throws EvalException

Description copied from class: OutermostExprContext

Returns NullNodeIterator.INSTANCE because this basic implementation does not support key().

Specified by:

getKeyedNodes in interface ExprContext

Overrides:

getKeyedNodes in class OutermostExprContext

Parameters:

keyName - name of the key

keyValue - searched value

node - the context node.

Returns:

nodes belonging to the same document as node having specified key with specified value.

The returned nodes don't need to be sorted by document order.

Throws:
