Method Detail

setDomain

void setDomain(java.lang.String domain)

Sets the domain for this operation

Parameters:

domain -

setOperationIdentifier

void setOperationIdentifier(java.lang.String operationIdentifier)

This method sets the operation identifier for a given operation

Parameters:

operationIdentifier -

setInstanceIdentifier

void setInstanceIdentifier(java.lang.String instanceIdentifier)

Sets the instance identifier associated with a given operation.

Parameters:

instanceIdentifier -

setVersionInformation

void setVersionInformation(long version)

Sets the version information for this operation.

Parameters:

version -

setProcessingDirectives

void setProcessingDirectives(java.util.Properties processingDirectives)

Set the processing directives for the operation

Parameters:

processingDirectives -

setDatasetCollection

void setDatasetCollection(DatasetCollection datasetCollection)

Establish the dataset needed by the application in question

Parameters:

datasetCollection -

setInitializationComplete

void setInitializationComplete()

Mark the initialization of the application as having completed

setTeminationConditionReached

void setTeminationConditionReached()

Mark the termination condition of this operation as having reached. If the execution profile of the operation is isStayAlive() the operation cannot be garbage collected till such time that this flag has been set.

setInitializationNeeded

void setInitializationNeeded(boolean needsInitialization)

Set/Unset whether this operation needs initialization.

Parameters:

needsInitialization -

setAsExecuteOnce

void setAsExecuteOnce()

Sets the operation as being executable exactly once.

setAsExecutePeriodically

void setAsExecutePeriodically(long executionInterval)

Sets the operation as being executable periodically at the specified intervals. If the specified execution interval is 0, the method simply returns without performing any actions. It would be as if this method was never invoked. This method will introduce additional upper and lower bounds subsequently.

Parameters:

executionInterval -

setAsExecuteFixedNumberOfTimes

void setAsExecuteFixedNumberOfTimes(int numOfTimes)

Sets the operation as being executable a fixed number of times. If the value that is specified is either 0 or 1, this method simply returns without performing any actions. It would be as if this method was never invoked.

Parameters:

numOfTimes -

setAsExecuteWhenDataAvailable

void setAsExecuteWhenDataAvailable()

Sets the operation as being executable when data is available

setAsStayAlive

void setAsStayAlive()

Sets the operation as being stayAlive. The operation will not be dismounted till such time that the termination condition associated with the operation has been set.
