Interface used by all aggregates over two inputs.
public interface IBinaryAggregate<TLeft,TRight,TState,TResult>type IBinaryAggregate<'Left, 'Right, 'State, 'Result> = interfacePublic Interface IBinaryAggregate(Of TLeft, TRight, TState, TResult)Type Parameters
- TLeft
The type of the left input being aggregated.
- TRight
The type of the right input being aggregated.
- TState
The type of the state object used for intermediate computation.
- TResult
The type of the computed result of the aggregation.
Methods
| AccumulateLeft() |
Provides an expression that describes how to take the aggregate state and a new data object from the left input and compute a new aggregate state. |
| AccumulateRight() |
Provides an expression that describes how to take the aggregate state and a new data object from the right input and compute a new aggregate state. |
| ComputeResult() |
Provides an expression that describes how to compute a final result from an aggregate state. |
| DeaccumulateLeft() |
Provides an expression that describes how to take the aggregate state and a retracted data object from the left input and compute a new aggregate state. |
| DeaccumulateRight() |
Provides an expression that describes how to take the aggregate state and a retracted data object from the right input and compute a new aggregate state. |
| Difference() |
Provides an expression that describes how to take two different aggregate states and subtract one from the other. |
| InitialState() |
Provides an expression that creates the initial state for the aggregate computation. |
