  +--weblogic.apache.xalan.lib.sql.ExtensionError

Direct Known Subclasses:

SQLExtensionError

public class ExtensionError

extends java.lang.Object

implements org.w3c.dom.traversal.NodeIterator, ContextNodeList, java.lang.Cloneable

A base class that will convert an exception into an XML stream that can be returned in place of the standard result. The XML format returned is a follows. Message from the Exception thrown Current stack information as CData If another class subclasses this class, there will be an oppurtitny to add specific information here. Each Extension class should implement their own specific Extension Error class.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Method Detail

processBaseError

protected void processBaseError(java.lang.Exception err)

populateSpecificData

protected void populateSpecificData(org.w3c.dom.Document doc,
                                    org.w3c.dom.Node node)

Other classes that extend this class will overrid this mehood to add any specific information.

getRoot

public org.w3c.dom.Node getRoot()

Specified by:

getRoot in interface org.w3c.dom.traversal.NodeIterator

getWhatToShow

public int getWhatToShow()

This attribute determines which node types are presented via the iterator. The available set of constants is defined in the NodeFilter interface.

Specified by:

getWhatToShow in interface org.w3c.dom.traversal.NodeIterator

Returns:

which node types are to be presented

getFilter

public org.w3c.dom.traversal.NodeFilter getFilter()

The filter used to screen nodes.

Specified by:

getFilter in interface org.w3c.dom.traversal.NodeIterator

Returns:

null.

getExpandEntityReferences

public boolean getExpandEntityReferences()

The value of this flag determines whether the children of entity reference nodes are visible to the iterator. If false, they will be skipped over.
To produce a view of the document that has entity references expanded and does not expose the entity reference node itself, use the whatToShow flags to hide the entity reference node and set expandEntityReferences to true when creating the iterator. To produce a view of the document that has entity reference nodes but no entity expansion, use the whatToShow flags to show the entity reference node and set expandEntityReferences to false.

Specified by:

getExpandEntityReferences in interface org.w3c.dom.traversal.NodeIterator

Returns:

true.

nextNode

public org.w3c.dom.Node nextNode()
                          throws org.w3c.dom.DOMException

Return the #Document node (one role the XStatement plays) the first time called; return null thereafter.

Specified by:

nextNode in interface org.w3c.dom.traversal.NodeIterator

Returns:

this or null.

Throws:

org.w3c.dom.DOMException -

previousNode

public org.w3c.dom.Node previousNode()
                              throws org.w3c.dom.DOMException

Specified by:

previousNode in interface org.w3c.dom.traversal.NodeIterator
