Constructor Detail

MPPTaskBuilder

public MPPTaskBuilder(ContentHandler parent)

Create a handler that builds a MPPTask from a particular portion of the document being scanned.

If this constructor is used then MPPObjectBuilder.setScope(java.lang.String) must be called to set the scope before the builder is used.

Parameters:

parent - the parent handler

MPPTaskBuilder

public MPPTaskBuilder(ContentHandler parent,
                      String localName)

Create a handler that builds a MPPTask from a particular portion of the document being scanned.

When the end tag for the specified scope element is encontered, control is passed back to the parent handler.

Parameters:

parent - the parent handler

localName - the localName of the scoping element

Method Detail

reset

public void reset()

Description copied from class: MPPObjectBuilder

Reset the builder so that it can be used again. This causes a fresh object to be created, the content buffer to be cleared and the extended attribute builder to be reset.

Overrides:

reset in class MPPObjectBuilder

createObject

protected MPPObject createObject()

Description copied from class: MPPObjectBuilder

Create the MPPObject that should be populated by this builder.

Specified by:

createObject in class MPPObjectBuilder

getTask

public final MPPTask getTask()

isUnsupported

protected boolean isUnsupported(String namespaceURL,
                                String localName,
                                String qName)

Description copied from class: MPPObjectBuilder

Returns true if the specified element contains data that should be ignored by this builder. If this returns true for a particular element, then control will be turned over to a IgnoreContentHandler until the element is complete.

Specified by:

isUnsupported in class MPPObjectBuilder

startElement

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

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class MPPObjectBuilder

Throws:

SAXException

endElement

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

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class MPPObjectBuilder

Throws:

SAXException

addPredecessor

private final void addPredecessor(long uid,
                                  int type)

Add the predecessor to the task using the correct ProjectLinkType. If there is no ProjectLinkType that corresponds to the type then the predecessor is not added.
