Constructor Detail

ObjectContentHandler

public ObjectContentHandler(ContentHandler parent)

Create a handler to process the child elements of a parent element. If this constructor is used, then setScope(java.lang.String, java.lang.String) must be called to set the parent and child tags and setBuilder(wt.projmgmt.msproject.mppobject.MPPObjectBuilder) must be called to set the builder before this handler can be used.

Parameters:

parent - the parent handler to return control to

ObjectContentHandler

public ObjectContentHandler(ContentHandler parent,
                            String parentTag,
                            String childTag)

Create a handler to process the child elements of a parent element. When the end tag for the parent element is encountered, control is passed back to the parent handler.

Parameters:

parent - the parent handler to return control to

parentTag - the tag that determines when control is passed back to the parent handler

childTag - the tag that specifies the child elements

Method Detail

setScope

public final void setScope(String parentTag,
                           String childTag)

Set the parent tag and child tag used for scoping this handlers work. Resets the handler and sets the builder's scope.

reset

public final void reset()

Reset the handler so that it can be used again. This causes the object map to be cleared and the object builder to be reset.

setBuilder

public void setBuilder(MPPObjectBuilder builder)

Set the builder to the specified MPPObjectBuilder. If this handler's scope is set, set the builder's scope appropriately. Set the builder's parent to be this handler.

getObjects

public final Map getObjects()

Get the objects that have been built by this handler.

addObject

protected void addObject(MPPObject mppObj)

Add an object to this handlers collection of objects. If mppObj is null then no object is added.

startElement

public void startElement(String namespaceURL,
                         String localName,
                         String qName,
                         Attributes atts)
                  throws SAXException

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class DefaultSAXContentHandler

Throws:

SAXException

endElement

public void endElement(String namespaceURL,
                       String localName,
                       String qName)
                throws SAXException

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class DefaultSAXContentHandler

Throws:

SAXException
