Constructor Detail

primitive_desc

public primitive_desc(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

primitive_desc

public primitive_desc(long size)

Native array allocator. Access with Pointer.position(long).

primitive_desc

public primitive_desc()

Default constructor. Produces an empty object.

primitive_desc

public primitive_desc(@Const @ByRef
                      eltwise_backward.desc adesc,
                      @Const @ByRef
                      engine aengine,
                      @Const @ByRef
                      eltwise_forward.primitive_desc hint_fwd_pd,
                      @Cast(value="bool")
                      boolean allow_empty)

Constructs a primitive descriptor for an elementwise backward propagation primitive.

Parameters:

adesc - Descriptor for an elementwise backward propagation primitive.

aengine - Engine to use.

hint_fwd_pd - Primitive descriptor for an elementwise forward propagation primitive. It is used as a hint for deciding which memory format to use.

allow_empty - A flag signifying whether construction is allowed to fail without throwing an exception. In this case an empty object will be produced. This flag is optional and defaults to false.
