-- The default COntext parameters in case of the GNAT ASIS implementation

-- -CA - a Context is made up by all the tree files in the tree search
-- path; the tree search path is not set, so the default is used,
-- and the default is the current directory;
-- -FT - only pre-created trees are used, no tree file can be created by
-- ASIS;
-- -SA - source files for all the Compilation Units belonging to the
-- Context (except the predefined Standard package) are considered
-- in the consistency check when opening the Context;
--
-- If you would like to use some other Context definition, you have to
-- replace the initialization expression in this declaration by
-- the corresponding Parameters string. See the ASIS Reference Manual for
-- the full details of the Context definition for the GNAT ASIS
-- implementation.

begin
-- The code below corresponds to the basic sequencing of calls to ASIS
-- queries which is mandatory for any ASIS application.
-- First, the ASIS implementation should be initialized
-- (Asis.Implementation.Initialize), then an application should define
-- an ASIS Context to process by associating the Context with an external
-- environment (Asis.Ada_Environments.Associate), then the Context should
-- be opened (sis.Ada_Environments.Open ). After that all the ASIS queries
-- may be used (the ASIS processing is encapsulated in
-- Context_Processing.Process_Context. When the ASIS analysis is over, the
-- application should release the system resources by closing the ASIS
-- Context (Asis.Ada_Environments.Close), breaking the association of the
-- Context with the external world (Asis.Ada_Environments.Dissociate) and
-- finalizing the ASIS implementation (Asis.Implementation.Finalize).
