udp_term_string_hook(+Scope, +Term, -String) is det[multifile, library(udp_broadcast)]

udp_term_string_hook(+Scope, -Term, +String) is semidet[multifile, library(udp_broadcast)]

Hook for serializing the message Term. The default writes %prolog\n, followed by the Prolog term in quoted notation while ignoring operators. This hook may use alternative serialization such as fast_term_serialized/2, use library(ssl) to realise encrypted messages, etc.

Arguments:

`Scope`	- is the scope for which the message is broadcasted. This can be used to use different serialization for different scopes.
`Term`	- encapsulates the term broadcasted by the application as follows: send`(ApplTerm)` Is sent by `broadcast(udp(Scope, ApplTerm))` request`(Id, ApplTerm)` Is sent by broadcast_request/1, where `Id` is a unique large (64 bit) integer. reply`(Id, ApplTerm)` Is sent to reply on a broadcast_request/1 request that has been received. Arguments are the same as above.

throws

- The hook may throw udp(invalid_message) to stop processing the message.
