4.16.4 Query Handling Predicates

ask_query(+QueryClass, +Query, +Help, -Answer) hookable
Prints the question Query, then reads and processes user input according to QueryClass, and returns the result of the processing, the abstract answer term Answer. The Help message is printed in case of invalid input.
query_hook(+QueryClass, +Query, +QueryLines, +Help, +HelpLines, -Answer) hook
user:query_hook(+QueryClass, +Query, +QueryLines, +Help, +HelpLines, -Answer)
Called by ask_query/4 before processing the query. If this predicate succeeds, it is assumed that the query has been processed and nothing further is done.
query_class_hook(+QueryClass, -Prompt, -InputMethod, -MapMethod, -FailureMode) hook
user:query_class_hook(+QueryClass, -Prompt, -InputMethod, -MapMethod, -FailureMode)
Provides the user with a method of overriding the call to 'SU_messages':query_class/5 in the preparation phase of query processing. This way the default query class characteristics can be changed.
'SU_messages':query_class(+QueryClass, -Prompt, -InputMethod, -MapMethod, -FailureMode) extendible
Predefined query class characteristics table.
'SU_messages':query_abbreviation(+QueryClass, -Prompt, -Pairs) extendible
Predefined query abbreviation table.
query_input_hook(+InputMethod, +Prompt, -RawInput) hook
user:query_input_hook(+InputMethod, +Prompt, -RawInput)
Provides the user with a method of overriding the call to 'SU_messages':query_input/3 in the input phase of query processing. This way the implementation of the default input methods can be changed.
'SU_messages':query_input(+InputMethod, +Prompt, -RawInput) extendible
Predefined query input methods.
query_map_hook(+MapMethod, +RawInput, -Result, -Answer) hook
user:query_map_hook(+MapMethod, +RawInput, -Result, -Answer)
Provides the user with a method of overriding the call to 'SU_messages':query_map/4 in the mapping phase of query processing. This way the implementation of the default map methods can be changed.
'SU_messages':query_map(+MapMethod, +RawInput, -Result, -Answer) extendible
