abstract member ReduceToInt : int64 * Java.Util.Functions.IToIntBiFunction * int * Java.Util.Functions.IIntBinaryOperator -> int
override this.ReduceToInt : int64 * Java.Util.Functions.IToIntBiFunction * int * Java.Util.Functions.IIntBinaryOperator -> int

Parameters

parallelismThreshold: Int64

the (estimated) number of elements needed for this operation to be executed in parallel

transformer: IToIntBiFunction

a function returning the transformation for an element

basis: Int32

the identity (initial default value) for the reduction

reducer: IIntBinaryOperator

a commutative associative combining function

Returns

Int32

the result of accumulating the given transformation of all (key, value) pairs

Attributes: RegisterAttribute

Remarks

Returns the result of accumulating the given transformation of all (key, value) pairs using the given reducer to combine values, and the given basis as an identity value.
