built-in predicate

protocol_property/2

Description

protocol_property(Protocol, Property)

Enumerates, by backtracking, the properties associated with the currently defined protocols. The valid properties are listed in the language grammar section on entity properties and described in the User Manual section on protocol properties.

Modes and number of proofs

protocol_property(?protocol_identifier, ?protocol_property) - zero_or_more

Errors

Protocol is neither a variable nor a valid protocol identifier:
type_error(protocol_identifier, Protocol)
Property is neither a variable nor a callable term:
type_error(callable, Property)
Property is a callable term but not a valid protocol property:
domain_error(protocol_property, Property)

Examples

% enumerate the properties of the monitoring built-in protocol:
| ?- protocol_property(monitoring, Property).

Property = source_data ;
Property = static ;
Property = built_in ;
