Methods
Accumulate() |
Provides an expression that describes how to take the aggregate state and a new data object and compute a new aggregate state. (Inherited from IAggregate<TInput,TState,TResult>) |
ComputeResult() |
Provides an expression that describes how to compute a final result from an aggregate state. (Inherited from IAggregate<TInput,TState,TResult>) |
Deaccumulate() |
Provides an expression that describes how to take the aggregate state and a retracted data object and compute a new aggregate state. (Inherited from IAggregate<TInput,TState,TResult>) |
Difference() |
Provides an expression that describes how to take two different aggregate states and subtract one from the other. (Inherited from IAggregate<TInput,TState,TResult>) |
InitialState() |
Provides an expression that creates the initial state for the aggregate computation. (Inherited from IAggregate<TInput,TState,TResult>) |
Sum() |
Provides an expression that describes how to take two different aggregate states and combine them. |
