Class AbstractTensoricCollector<V,T,O>

java.lang.Object

org.tensorics.core.tensor.stream.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.
