Method Detail

iterator

public TensorIterator iterator()

Returns:

an iterator over entries in the mapping from dimensions to the value.

asList

public java.util.List<?> asList()

Specified by:

asList in class DenseTensor

Returns:

the list of values in their unraveled order. This in combination with the shape is enough to restore the entire tensor, as the dimensions can be calculated from the shape.
