Field Documentation

const char* MsgInfo::name

Human-readable name of message, like "CkMarshallMsg".

Definition at line 101 of file register.h.

CkPackFnPtr MsgInfo::pack

A message pack function converts the (possibly complex) message into a flat array of bytes.

This method is called whenever messages are sent or duplicated, so for speed messages normally have a layout which allows this conversion to be done in-place, typically by just moving some pointers around in the message.

There was once a time when the pack function could be NULL, meaning the message can be sent without packing, but today the pack function is always set. Note: pack and unpack have nothing to do with the PUP framework.

CkUnpackFnPtr MsgInfo::unpack

A message unpack function converts a flat array of bytes into a living message.

It's just the opposite of pack.

Definition at line 120 of file register.h.

CkDeallocFnPtr MsgInfo::dealloc

A message deallocation function deletes the message with the appropriate actions.

Definition at line 125 of file register.h.

size_t MsgInfo::size

This message body's allocation size.

This does *not* include any dynamically allocated portion of the message, so is a lower bound on the message size.
