ObservationParameters

The ObservationParameters interface is used to set filter conditions for the IntermediateResultReceiver, so that only intermediate results meeting specific conditions will be called back.

interface ObservationParameters {
    getObservedResultUnitTypes(): BigInt;
    setObservedResultUnitTypes(types: BigInt): void;
    isResultUnitTypeObserved(type: EnumIntermediateResultUnitType): boolean;
    addObservedTask(taskName): void;
    removeObservedTask(taskName: string): void;
    isTaskObserved(ctaskName: string): boolean;
}

getObservedResultUnitTypes

Gets the types of intermediate result units that have been observed.

getObservedResultUnitTypes(): BigInt;

Return value

The observed types of intermediate result units.

setObservedResultUnitTypes

Sets the types of intermediate result units that have been observed.

setObservedResultUnitTypes(types: BigInt): void;

Parameters

types: The observed types of intermediate result units.

isResultUnitTypeObserved

Determines whether the specified result unit type was observed.

isResultUnitTypeObserved(type: EnumIntermediateResultUnitType): boolean;

Return value

Returns a boolean value indicating whether the specified result unit type was observed.

addObservedTask

Adds observed task name to be notified when relevant results are available.

addObservedTask(taskName): void;

Parameters

taskName: The specified task name.

removeObservedTask

Remove the observed task name so that intermediate results generated by the task are not notified.

removeObservedTask(taskName: string): void;

Parameters

taskName: The specified task name.

isTaskObserved

Determines whether the specified task was observed.

isTaskObserved(taskName: string): boolean;

Parameters

taskName: The specified task name.

Return value

Returns a boolean value indicating whether the specified task was observed.
