Description

Interface Summary

IProcessor	Interface for processor implementations
IProcessorTask	An interface representing a ProcessorTask (created to break the dependancy between ProcessorTaskImpl and ProcessorTaskWorker).
ScuflModelEventListener	Implementors can respond to ScuflModelEvent messages, and may register themselves with a ScuflModel.
ScuflWorkflowProcessor	Interface to help seperate the cyclic dependancies between WorkflowProcessor and ScuflModel
ScuflWorkflowProcessorFactory	Inteface to help break the cyclic dependancy between WorkflowProcessorFactory and Scufl

Class Summary

AlternateProcessor	Represents an alternate processor to be used in case of failures in the primary.
AnnotationTemplate	An AnnotationTemplate object represents a single possible RDF statement that may be generated as a side effect of the invocation of a processor task instance.
ConcurrencyConstraint	Represents a concurrency constraint between two processors
CrossNode	A cross product node in an iterator tree model
DataConstraint	Represents a data dependancy between two processors
DotNode	A dot product node in an iterator tree model
InputPort	A port that consumes data on behalf of a processor
InternalSinkPortHolder	A Processor subclass to hold ports for the overall workflow outputs, these ports are therefore held as input ports, acting as they do as data sinks.
InternalSourcePortHolder	A Processor subclass to hold ports for the overal workflow inputs.
IterationStrategy	Defines the manner in which iterators should be constructed for a given processor instance.
LeafNode	A leaf node in an iterator tree model
MinorScuflModelEvent	Signifies a change in the model that might be of interest to a view.
OutputPort	A port that exposes output data on behalf of a processor
Port	An abstract superclass of all processor ports
PortSemanticMarkup	A SemanticMarkup for Ports that fires ScuflModelEvents when markup elements are changed.
PortTest
Processor	An abstract superclass of the various processor subtypes
ScuflModel	Represents a single scufl workflow model
ScuflModelAddEvent	COMMENT
ScuflModelEvent	Signifies a change in the model that might be of interest to a view
ScuflModelEventPrinter	Trivially implements the ScuflModelEventListener by printing a textual representation of incoming events to a given PrintStream
ScuflModelRemoveEvent	COMMENT
ScuflModelRenameEvent	COMMENT
ScuflModelTest
SemanticMarkup
WorkflowDescription	A container class for the metadata about a workflow definition, including LSID if available, description and author information
XScufl	Provides a place to store constants relating to the XML Scufl representation such as namespaces etc.

Exception Summary

ConcurrencyConstraintCreationException	Thrown by the ConcurrencyConstraint constructor if the arguments passed in are invalid.
DataConstraintCreationException	Thrown by the DataConstraint constructor if the arguments passed in are invalid.
DuplicateConcurrencyConstraintNameException	Thrown by the constructor of the ConcurrencyConstraint class when a duplicate name is added to a particular ScuflModel
DuplicatePortNameException	Thrown by the constructor of the Port class when a duplicate name is added to a particular processor
DuplicateProcessorNameException	Thrown by the constructor of the Processor class when a duplicate name is added to a particular ScuflModel
MalformedNameException	Thrown by the locatePort method in ScuflModel when the supplied name doesn't conform to the naming rules.
PortCreationException	Thrown by the Port constructor if either of the arguments passed are null, or if the name is the empty string.
ProcessorCreationException	Thrown by the Processor constructor if either of the arguments passed are null, or if the name is the empty string.
ScuflException	Base class for all Scufl exceptions
SetOnlineException	Thrown from the model when there is a problem going from offline to online mode - normally this is a similar problem to the workflow load but I guess there could be additional factors.
UnknownPortException	Thrown by the Processor classes when then can't find a particular named port.
UnknownProcessorException	Thrown by the ScuflModel when it can't find a particular named processor.
