current_store(?StoreHandle)

StoreName is a visible store name
StoreHandle
A variable or a store name (atom or compound)

Description

Used to check whether StoreName is the name of a visible store, or to enumerate all visible store names in the context module.

Note that this predicate will only accept/generate store names that have been created with local/1, store/1, not anonymous store handles created via store_create/1. Note: StoreHandle gets unified with an atom or a compound term, and the store is identified by this term's toplevel functor together with the context module.

Modes and Determinism

Modules

This predicate is sensitive to its module context (tool predicate, see @/1).

Fail Conditions

StoreName is not a visible store name

Exceptions

(5) type error
StoreHandle is neither atom nor compound term nor variable

Examples

    :- local store(shed).
    :- local store(warehouse/3).

    ?- current_store(shed).
    Yes (0.00s cpu)

    ?- current_store(heap).
    No (0.00s cpu)

    ?- current_store(X).
    X = shed
    More (0.00s cpu) ? ;

    X = warehouse(_184, _185, _186)
    More (0.00s cpu) ? ;

    No (0.00s cpu)
