Defines classes and interfaces for workflow level entities and events.

Interface Summary

Interface	Description
Condition	Defines the base interface for a condition which must be satisfied before a processor can commence invocation.
Configurable<ConfigurationType>	Interface for workflow items that can be configured from a bean.
Dataflow	Top level definition object for a dataflow workflow.
DataflowInputPort	An input port on a Dataflow contains a nested output port within it.
DataflowOutputPort	Output port of a DataFlow, exposes an internal EventHandlingInputPort into which the internal workflow logic pushes data to be exposed outside the workflow boundary.
DataflowPort	Defines that the implementing port belongs to a Dataflow
DataflowValidationReport	Contains a validation report from a dataflow validation check.
Datalink	A single point to point data link from an instance of EventForwardingOutputPort to an instance of EventHandlingInputPort
Edit<TargetType>	The workflow object model exposed by this API is read only.
Edits	Defines the set of all available edit actions over a workflow model.
EventForwardingOutputPort	An extension of OutputPort defining a set of target EventReceivingInputPorts to which internally generated events will be relayed.
EventHandlingInputPort	Input port capable of receiving and reacting to workflow events.
FailureTransmitter	Used to message interested parties when a top level failure occurs within a Dataflow
FilteringInputPort	A filtering input port is one capable of filtering events to only pass through data events at a certain depth.
InputPort	Marker interface denoting that the instance is an input port.
Merge	Allows multiple outputs to be routed to a single input within the dataflow.
MergeInputPort	Input port on a Merge object
MergeOutputPort	An EventForwardingOutputPort that is associated with Merge instances.
MergePort	An input or output Port for a Merge.
NamedWorkflowEntity	Entities existing directly within a workflow such as Processors, Merge operators and other potential future extensions exist within a naming scheme.
OutputPort	Port representing the output of an activity, processor or workflow.
Port	Named port which receives events from some other entity and handles them appropriately.
Processor	A single node within the dataflow digraph, the Processor is the basic functional unit within a Taverna workflow.
ProcessorInputPort	Input port on a Processor, is both a filtering input port and a processor port
ProcessorOutputPort	Input port on a Processor, is both an event forwarding output port and a processor port
ProcessorPort	An ProcessorInputPort or ProcessorOutputPort belonging to a Processor.
RunDeletionListener	A RunDeletionListener is notified when a run is deleted.
TokenProcessingEntity	Superinterface for all classes within the workflow model which consume and emit workflow data tokens.
WorkflowItem	An item that forms a structural part of a Workflow.

Class Summary

Class	Description
AbstractOutputPort	Simple implementation of OutputPort, extends AbstractPort and adds the granular depth bean getter.
AbstractPort	Port definition with depth and name
CompoundEdit	Implementation of Edit which contains an ordered list of child edits.
OrderedPair<T>	A simple generic class to hold a pair of same type objects.
ProcessorFinishedEvent	An event saying that a processor with a given owning process has finished with execution (that includes the whole dispatch stack - iterations of the processor and all).

Exception Summary

Exception	Description
ConfigurationException	Thrown when attempting to configure a Configurable with an invalid configuration.
EditException	Superclass of all exceptions thrown when altering the workflow model through the edit manager.
InvalidDataflowException	Thrown if attempting to use a workflow that is not valid.
NamingException	Potentially thrown when an edit fails due to naming of entities created or modified by the edit.
WorkflowStructureException	Thrown predominantly at runtime under circumstances that suggest an inconsistancy in the workflow model.

Annotation Types Summary

Annotation Type	Description
ControlBoundary	Denotes that the associated type creates a boundary of control within the dataflow.
