Method Detail

AddKernel

@ByVal
public Status AddKernel(@ByVal
                                ScalarAggregateKernel kernel)

\brief Add a kernel (function implementation). Returns error if the kernel's signature does not match the function's arity.

DispatchExact

@ByVal
 @Cast(value="arrow::Result<const arrow::compute::Kernel*>*")
public KernelResult DispatchExact(@Const @ByRef
                                                                                                         ValueDescrVector values)

Description copied from class: Function

\brief Return a kernel that can execute the function given the exact argument types (without implicit type casts or scalar->array promotions). NB: This function is overridden in CastFunction.
