interface |
Activity<ConfigurationType>
Defines a single abstract or concrete invokable activity.
|
interface |
AsynchronousActivity<ConfigurationType>
A concrete invokable activity with an asynchronous invocation API and no
knowledge of invocation context.
|
interface |
MonitorableAsynchronousActivity<ConfigType>
An extension of AsynchronousActivity with the additional stipulation that
implementing classes must return a set of monitorable properties for the
activity invocation instance when invoked.
|
interface |
SupersededActivity<ConfigurationType>
A superseded activity is one which has been replaced be another activity type
of similar functionality but different configuration and name

Modifier and Type | Class and Description |
---|---|
class |
AbstractActivity<ConfigType>
Convenience abstract superclass for generic Activity instances.
|
class |
AbstractAsynchronousActivity<ConfigType>
Abstract superclass for asynchronous activities.
|
class |
DisabledActivity
A disabled activity is a wrapper for an Activity that is offline or similarly
disabled.
|
class |
NonExecutableActivity<T>
A non-executable activity is a wrapper for an Activity that cannot be
executed, for example because it is offline or unrecognized.
|
class |
UnrecognizedActivity
An unrecognized activity is an activity that was not recognized when the
workflow was opened.
|
Modifier and Type | Interface and Description |
---|---|
interface |
DispatchLayer<ConfigurationType>
Layers within the dispatch stack define a control flow to handle dispatch of
jobs from a queue (generated by the iteration system) to appropriate
activities.
|
interface |
PropertyContributingDispatchLayer<ConfigType>
Used by dispatch layers which can contribute property information to their
parent processor instance.
|

DispatchStackImpl.TopLayer |
Modifier and Type | Class and Description |
---|---|
class |
ErrorBounce
Receives job events, checks to see whether any parameters in the job are
error tokens or collections which contain errors.
|
class |
Failover
Failure handling dispatch layer, consumes job events with multiple activities
and emits the same job but with only the first activity.
|
class |
IntermediateProvenance
Sits above the
Invoke layer and collects information about the
current workflow run to be stored by the ProvenanceConnector . |
class |
Invoke
Context free invoker layer, does not pass index arrays of jobs into activity
instances.
|
class |
Loop
A layer that allows while-style loops.
|
class |
Parallelize
Dispatch layer which consumes a queue of events and fires off a fixed number
of simultaneous jobs to the layer below.
|
class |
Retry
Implements retry policy with delay between retries and exponential backoff
|
class |
Stop
This layer allows for the cancellation, pausing and resuming of workflow
runs.
