% This header file auto-defines the Seaplus base, generic service functions.
% It is meant to be included by the bridging modules (ex: for a Foobar service,
% by foobar.erl).
-define( service_module_name, ?MODULE ).
-define( service_registration_name, ?service_module_name ).
-export([ % Base service behaviour:
% Auto-exported by the Seaplus parse transform:
% start/0, start_link/0, stop/0,
activate_seaplus/1 ]).
% The following start/0, start_link/0 and stop/0 functions are commented-out, as
% they are automatically defined appropriately by the Seaplus parse transform
% now.
% Starts the service.
% Preferred form, to detect crashes of the driver and/or of the integrated
% library: the current process will then trap EXIT signals, and thus Seaplus
% will throw a { driver_crashed, ErrorReason } exception if appropriate.
% As a result, the user code may catch this exception and react accordingly (ex:
% by restaring the driver).
%-spec start() -> void().
%start() ->
% Allows to register and identify target executable:
% seaplus:start( ?service_module_name ).
% Starts and links the service.
% The current process will then not trap EXIT signals, and thus will crash
% whenever its associated driver crashed (because of the driver itself, or
% because of the integrated library).
% Note that start/0 is the generally preferred form.
%-spec start_link() -> void().
%start_link() ->
% Allows to register and identify target executable:
% seaplus:start_link( ?service_module_name ).
% Restarts the support of this foobar service (ex: to overcome a detected crash
% thereof).
% Note: performs a start/0, not a start_link/0.
-spec restart() -> void().
restart() ->
% So that user-code (not Seaplus one only) is triggered as well:
% Stops the service.
%-spec stop() -> void().
%stop() ->
% seaplus:stop( ?service_module_name ).
% None defined yet:
-type seaplus_option() :: any().
% Simply defining that function allows to activate the Seaplus transformations
% for the current module (acts as a AST marker, and will be detected and removed
% by the Seaplus parse transform).
