public ProcessElement setPassThruOutput(java.lang.Boolean passThruOutput)
                                 throws java.lang.IllegalStateException

Does this processElement pass through output from the last executed task (i.e. transient state)?

See taskInputExpressions for details on the transient state outputs.

Note that this property does not affect the task at all but is an indicator to the user and to the workflow editor of the behavior of the task as coded (See Process.passThruTaskOutput()).

Parameters:

passThruOutput - New passThruOutput value. Default value is true

Returns:

ProcessElement instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getPassThruOutput

public java.lang.Boolean getPassThruOutput()

See taskInputExpressions for details on the transient state outputs.

Note that this property does not affect the task at all but is an indicator to the user and to the workflow editor of the behavior of the task as coded (See Process.passThruTaskOutput()).

Returns:

Current passThruOutput value. Default value is true

setSupportsMultipleInputRecords

public ProcessElement setSupportsMultipleInputRecords(java.lang.Boolean supportsMultipleInputRecords)
                                               throws java.lang.IllegalStateException

Does this processElement support being called multiple times for multiple records in the last task output?

By default a processElement is executed exactly once, however, for a task that can process records from the last task output it can be useful to handle each incoming record individually. Setting this property indicates to the process that if the last task output is an array, it should be executed once per value in the array. Normal processing of taskInputExpressions or use of Process.getLastTaskOutput() will have exactly one record except uses of the output for criteria values where the full output is used at once.

Processing of the task can determine that multiple incoming records should not result in multiple calls and set forceSingle. For example, a task that uses last task output for a criteria or for values should set forceSingle=true when a criteria is used because multiple calls do not make sense.

Parameters:

supportsMultipleInputRecords - New supportsMultipleInputRecords value. Default value is null

Returns:

ProcessElement instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getSupportsMultipleInputRecords

public java.lang.Boolean getSupportsMultipleInputRecords()

Does this processElement support being called multiple times for multiple records in the last task output?

By default a processElement is executed exactly once, however, for a task that can process records from the last task output it can be useful to handle each incoming record individually. Setting this property indicates to the process that if the last task output is an array, it should be executed once per value in the array. Normal processing of taskInputExpressions or use of Process.getLastTaskOutput() will have exactly one record except uses of the output for criteria values where the full output is used at once.

Processing of the task can determine that multiple incoming records should not result in multiple calls and set forceSingle. For example, a task that uses last task output for a criteria or for values should set forceSingle=true when a criteria is used because multiple calls do not make sense.

Returns:

Current supportsMultipleInputRecords value. Default value is null

setTypeTitle

public ProcessElement setTypeTitle(java.lang.String typeTitle)
                            throws java.lang.IllegalStateException

Optional short, descriptive title for this process element. Used by an editor as a title for process elements of this type.

Returns:

Current typeTitle value. Default value is null

completeElement

public void completeElement(Process process)

StringMethod called when a processElement completes. Typically used to clear transient state applied to the task while running like forceSingle so it can be executed again later. See also reset().

Parameters:

process - the containing process

executeElement

public java.lang.Boolean executeElement(Process process)

Method called by Process to have the processElement perform its work. There is no default implementation by ProcessElement, however, all of the system-provided subclasses do implement this method. An implementation or override of this method is one possible customization point. Some classes like ScriptTask perform other means to add customization. For ScriptTask, custom code is expected to handle the ScriptTask.execute() method instead.

Any implementation of this method must return true if all the work this element needed to perform was completed. Return false if additional work is being performed asynchronously and the process should be paused until element restarts it. Once asynchronous work is complete the task must call Process.start() to restart the workflow with the next task.

Parameters:

process - the process that is handling the workflow

Returns:

return true if all the work this element needed to perform was completed. Return false if additional work is being performed asynchronously and the process should be paused until element restarts it.

getDynamicValue

public java.lang.String getDynamicValue(java.lang.String value,
                                        Process process)

Resolves a dynamic value as taskInputExpressions or returns the value as-is.

Parameters:

value - the value to resolve

process - the current process

Returns:

the resolved value

getElementDescription

public java.lang.String getElementDescription()

Returns a text description of the element derived from the configuration.

If no override is provided by the concrete ProcessElement implementation the description is returned.

Returns:

the derived element description

Updates references to a global ID within the properties of this process element (i.e. rename). This method is not called as part of workflow execution but is used by Reify to keep workflow event handlers in sync with ID changes within the screen.

Each processElement or Task that has properties that save global IDs (like a component ID or criteria referencing ruleContext) must be able to update its references on demand by overriding this method or defer to its superclass.

Update references to a binding $last within properties of this processElement. This method is not called as part of workflow execution but is used by the com.smartgwt.client.tools.WorkflowEditor to adjust last task references as new tasks are inserted.

Each processElement or Task that has properties supporting taskInputExpressions using the $last syntax must be able to update its references on demand by overriding this method or defer to its superclass.

                                                   java.lang.String taskType)

Updates a set of TaskInputExpression values containing $last references. Any implicit reference to the last task is updated to reference a last task of a specified taskType.

For example, a value of "$last.sequenceNo" would be replaced with "$last[fetch].sequenceNo" if the taskType is "fetch". Existing "$last[...]" references are left as-is.

This method is a helper to implement task-specific updateLastElementBindingReferences().

Parameters:

values - the object to be updated

taskType - the taskType to be used in new reference

Returns:

true if any references were update; false otherwise
