deferred class ReaderModule from Interface inherits TShared
|
|
|
|
---Purpose : Defines unitary operations required to read an Entity from a
|
|
-- File (see FileReaderData, FileReaderTool), under control of
|
|
-- a FileReaderTool. The initial creation is performed by a
|
|
-- GeneralModule (set in GeneralLib). Then, which remains is
|
|
-- Loading data from the FileReaderData to the Entity
|
|
--
|
|
-- To work, a GeneralModule has formerly recognized the Type read
|
|
-- from FileReaderData as a positive Case Number, then the
|
|
-- ReaderModule reads it according to this Case Number
|
|
|
|
uses Transient, FileReaderData, Check
|
|
|
|
raises DomainError
|
|
|
|
is
|
|
|
|
CaseNum (me; data : FileReaderData; num : Integer) returns Integer
|
|
is deferred;
|
|
---Purpose : Translates the type of record <num> in <data> to a positive
|
|
-- Case Number. If Recognition fails, must return 0
|
|
|
|
Read (me; casenum : Integer; data : FileReaderData; num : Integer;
|
|
ach : in out Check; ent : mutable Transient)
|
|
---Purpose : Performs the effective loading from <data>, record <num>,
|
|
-- to the Entity <ent> formerly created
|
|
-- In case of Error or Warning, fills <ach> with messages
|
|
-- Remark that the Case Number comes from translating a record
|
|
raises DomainError is deferred;
|
|
-- Can raise any exception, while it is preferable to prevent
|
|
-- them and fill the Check
|
|
|
|
NewRead (me; casenum : Integer; data : FileReaderData; num : Integer;
|
|
ach : in out Check; ent : out mutable Transient) returns Boolean
|
|
---Purpose : Specific operator (create+read) defaulted to do nothing.
|
|
-- It can be redefined when it is not possible to work in two
|
|
-- steps (NewVoid then Read). This occurs when no default
|
|
-- constructor is defined : hence the result <ent> must be
|
|
-- created with an effective definition from the reader.
|
|
-- Remark : if NewRead is defined, Copy has nothing to do.
|
|
--
|
|
-- Returns True if it has produced something, false else.
|
|
-- If nothing was produced, <ach> should be filled : it will be
|
|
-- treated as "Unrecognized case" by reader tool.
|
|
raises DomainError is virtual;
|
|
-- Can raise any exception, while it is preferable to prevent
|
|
-- them and fill the Check
