Typedef Documentation

MessageEnvelopeType

template<MessageEnvelopeLevel level, typename T >

using kamping::plugin::grid_plugin_helpers::MessageEnvelopeType

Initial value:

 std::conditional_t<
    level == MessageEnvelopeLevel::no_envelope,
    T,
    std::conditional_t<
        level == MessageEnvelopeLevel::source,
        MessageEnvelope<T, Source>,
        MessageEnvelope<T, Source, Destination>>>

Select the right MessageEnvelope depending on the provided MsgEnvelopeLevel.

Enumeration Type Documentation

MessageEnvelopeLevel

enum kamping::plugin::MessageEnvelopeLevel

Descriptor for different levels for message envelopes used in indirect communication.

Enumerator
no_envelope	do not use an envelope at all (if possible)
source	only additionally add the source PE in the envelope (if possible)
source_and_destination	add source and destination PE in the envelope
