Direct Known Subclasses:

UIXParseFactory

public class UIXParseFactory

extends java.lang.Object

Factory for creating UIX objects during parsing. UINodeParser will use the registered UIXParseFactory to create all UINodes, AttributeMaps, NodeLists, and ContextMaps during parsing. Note, however, that if a particular UINode does not contain any attributes, or any indexed children, or any named children, then the corresponding collection object will not be created.

When using the UIX Servlet, the UIXParseFactory can be overridden by subclassing either the BajaContext or the PageBroker and overriding the getService() method to handle UIXParseFactory.class.

Method Detail

getUIXParseFactory

public static UIXParseFactory getUIXParseFactory(ParseContext context)

Gets the UIXParseFactory from a ParseContext. If one has not been explicitly set, a default factory will be created - so this function will never return null.

setUIXParseFactory

public static void setUIXParseFactory(ParseContext context,
                                      UIXParseFactory factory)

Sets the UIXParseFactory on a ParseContext.

parseStarted

public void parseStarted(ParseContext context)

Called as notification that a parse is starting.

parseEnded

public void parseEnded(ParseContext context)

Called as notification that a parse is ending.

createUINode

public BaseMutableUINode createUINode(ParseContext context,
                                      UINodeType nodeType,
                                      java.lang.String namespace,
                                      java.lang.String localName,
                                      org.xml.sax.Attributes attrs)
                               throws java.lang.InstantiationException,
                                      java.lang.IllegalAccessException

Creates a UINode. The default implementation will delegate to the UINodeType; if a parse factory does not have specific knowledge about a specific type of UINode, it should follow this behavior.

Parameters:

context - the ParseContext

nodeType - a UINodeType identifying the object.

namespace - the namespace of the UINode

localName - the local name of the UINode

attrs - the SAX attributes for the UINode.

createAttributeMap

public AttributeMap createAttributeMap(ParseContext context,
                                       BaseMutableUINode node,
                                       int sizeHint)

Creates an AttributeMap.

Parameters:

context - the ParseContext

node - the BaseMutableUINode created by createUINode()

sizeHint - a hint about how big the attribute map might be; if zero or negative, a default size should be assumed.

createUINodeList

public UINodeList createUINodeList(ParseContext context,
                                   BaseMutableUINode node,
                                   int lengthHint)

Creates a UINodeList.

Parameters:

context - the ParseContext

node - the BaseMutableUINode created by createUINode()

sizeHint - a hint about how big the node list might be; if zero or negative, a default size should be assumed.

createContextMap

public ContextMap createContextMap(ParseContext context,
                                   BaseMutableUINode node,
                                   int sizeHint)

Creates a ContextMap.

Parameters:

context - the ParseContext

node - the BaseMutableUINode created by createUINode()

sizeHint - a hint about how big the context map might be; if zero or negative, a default size should be assumed.
