Package jep
Class NDArray<T>
java.lang.Object
jep.NDArray<T>
Represents a numpy.ndarray in Java. If Jep was compiled with numpy support, this
object will not be wrapped as a PyJobject in the Python
sub-interpreter(s), it will instead be transformed into a numpy.ndarray
automatically (and vice versa). The transformation in either direction occurs
with a memcpy
, therefore changes in the array in one language
will not affect the array in the other language.
NDArrays only support Java primitive arrays as the underlying type of data. The data can conceptually be multi-dimensional, but it must be represented as a one-dimensional array in Java to ensure the memory is contiguous.
