Package org.tensorics.core.tensor.stream

Class AbstractTensoricCollector<V,​T,​O>

  • Type Parameters:
    V - stream elements
    T - elements of the tensor to be produced
    O - output (e.g. Tensor<T> or Tensorbacked<T>)
    All Implemented Interfaces:
    java.util.stream.Collector<V,​java.util.Map<Position,​T>,​O>
    Direct Known Subclasses:
    TensorbackedCollector, TensorCollector
    public abstract class AbstractTensoricCollector<V,​T,​O>
extends java.lang.Object
implements java.util.stream.Collector<V,​java.util.Map<Position,​T>,​O>
    Abstract base class for a stream Collector which is backed by a map of Position to an arbitrary value, from which a Tensor or Tensorbacked can be built in the finalization step.
