Read-only arrays (usually) do not define Set methods. Thus, using one in
an Invoke argument that does output will result in compile errors. To
help avoid that, modify the type checks to differentiate input and
output arrays.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
Previously, the operator for a Transport class took the object being
transported to the execution environment and the size of the output
domain. This change also passes in the control-side argument for the
input domain. This will help check input array sizes as well as make
other potential transformations based on the input domain.
The WholeArrayIn, WholeArrayInOut, and WholeArrayOut ControlSignature
tags behave similarly to using an ExecObject tag with an
ExecutionWholeArray or ExecutionWholeArrayConst object. However, the
WholeArray* tags can simplify some implementations in two ways. First,
it allows you to specify more precisely what data is passed in. You have
to pass in an ArrayHandle or else an error will occur (as opposed to be
able to pass in any type of execution object). Second, this allows you
to easily pass in arrays stored in DynamicArrayHandle objects. The
Invoke mechanism will automatically find the appropriate static class.
This cannot be done easily with ExecutionWholeArray.
Previously, all arrays passed to worklets were designated as either
input or output. No in-place operation was permitted. This change adds
the FieldInOut tag for ControlSignature in both WorkletMapField and
WorkletMapTopology that allows you to read and write from the same
array.
It's easy to put accidently put something that is not a valid tag in a
ControlSignature or ExecutionSignature. Previously, when you did that
you got a weird error at the end of a very long template instantiation
chain that made it difficult to find the offending worklet.
This adds some type checks when the dispatcher is instantated to check
the signatures. It doesn't point directly to the signature or its
parameter, but it is much closer.
The Transport class is responsible for moving data from the control
environment to the execution environment. (Actually, it might be more
accurate to say it gets the execution environment associated with a
given control object.) The Transport class is templated with a tag that
controls the mechanism used for the transport.
