class Static from Interface inherits TypedValue from Interface
---Purpose : This class gives a way to manage meaningfull static variables,
-- used as "global" parameters in various procedures.
--
-- A Static brings a specification (its type, constraints if any)
-- and a value. Its basic form is a string, it can be specified
-- as integer or real or enumerative string, and queried as such.
-- Its string content, which is a Handle(HAsciiString) can be
-- shared by other data structures, hence gives a direct on line
-- access to its value.
--
-- All this description is inherited from TypedValue
--
-- A Static can be given an initial value, it can be filled from,
-- either a set of Resources (an applicative feature which
-- accesses and manages parameter files), or environment or
-- internal definition : these define families of Static.
-- In addition, it supports a status for reinitialisation : an
-- initialisation procedure can ask if the value of the Static
-- has changed from its last call, in this case does something
-- then marks the Status "uptodate", else it does nothing.
--
-- Statics are named and recorded then accessed in an alphabetic
-- dictionary

is
Create (family, name : CString;
type : ParamType from Interface = Interface_ParamText;
init : CString = "") returns mutable Static
---Purpose : Creates and records a Static, with a family and a name
-- family can report to a name of ressource or to a system or
-- internal definition. The name must be unique.
--
-- type gives the type of the parameter, default is free text
-- Also available : Integer, Real, Enum, Entity (i.e. Object)
-- More precise specifications, titles, can be given to the
-- Static once created
--
-- init gives an initial value. If it is not given, the Static
-- begin as "not set", its value is empty
raises InterfaceError;
-- Error if <name> is already recorded, or <type> not supported
-- See also class method Init
Create (family, name : CString; other : Static) returns mutable Static;
---Purpose : Creates a new Static with same definition as another one
-- (value is copied, except for Entity : it remains null)
PrintStatic (me; S : Messenger from Message);
---Purpose : Writes the properties of a
-- parameter in the diagnostic file. These include:
-- - Name
-- - Family,
-- - Wildcard (if it has one)
-- - Current status (empty string if it was updated or
-- if it is the original one)
-- - Value
Family (me) returns CString;
---Purpose : Returns the family. It can be : a resource name for applis,
-- an internal name between : $e (environment variables),
-- $l (other, purely local)
SetWild (me : mutable; wildcard : Static);
---Purpose : Sets a "wild-card" static : its value will be considered
-- if <me> is not properly set. (reset by set a null one)
Wild (me) returns Static;
---Purpose : Returns the wildcard static, which can be (is most often) null
-- -- Update Status -- --
SetUptodate (me : mutable);
---Purpose : Records a Static has "uptodate", i.e. its value has been taken
-- into account by a reinitialisation procedure
-- This flag is reset at each successful SetValue
UpdatedStatus (me) returns Boolean;
---Purpose : Returns the status "uptodate"
-- --
-- -- Class methods : dictionary of statics -- --
-- --
Init (myclass; family, name : CString;
type : ParamType from Interface;
init : CString = "") returns Boolean;
---Purpose : Declares a new Static (by calling its constructor)
-- If this name is already taken, does nothing and returns False
-- Else, creates it and returns True
-- For additional definitions, get the Static then edit it
Init (myclass; family, name : CString;
type : Character;
init : CString = "") returns Boolean;
---Purpose : As Init with ParamType, but type is given as a character
-- This allows a simpler call
-- Types : 'i' Integer, 'r' Real, 't' Text, 'e' Enum, 'o' Object
-- '=' for same definition as, <init> gives the initial Static
-- Returns False if <type> does not match this list
Static (myclass; name : CString) returns mutable Static;
---Purpose : Returns a Static from its name. Null Handle if not present
IsPresent (myclass; name : CString) returns Boolean;
---Purpose : Returns True if a Static named <name> is present, False else
CDef (myclass; name : CString; part : CString) returns CString;
---Purpose : Returns a part of the definition of a Static, as a CString
-- The part is designated by its name, as a CString
-- If the required value is not a string, it is converted to a
-- CString then returned
-- If <name> is not present, or <part> not defined for <name>,
-- this function returns an empty string
--
-- Allowed parts for CDef :
-- family : the family
-- type : the type ("integer","real","text","enum")
-- label : the label
-- satis : satisfy function name if any
-- rmin : minimum real value
-- rmax : maximum real value
-- imin : minimum integer value
-- imax : maximum integer value
-- enum nn (nn : value of an integer) : enum value for nn
-- unit : unit definition for a real
IDef (myclass; name : CString; part : CString) returns Integer;
---Purpose : Returns a part of the definition of a Static, as an Integer
-- The part is designated by its name, as a CString
-- If the required value is not a string, returns zero
-- For a Boolean, 0 for false, 1 for true
-- If <name> is not present, or <part> not defined for <name>,
-- this function returns zero
--
-- Allowed parts for IDef :
-- imin, imax : minimum or maximum integer value
-- estart : starting number for enum
-- ecount : count of enum values (starting from estart)
-- ematch : exact match status
-- eval val : case determined from a string
-- Querying and Setting --
-- (must useful ones; for other, see methods of instance above)
IsSet (myclass; name : CString; proper : Boolean = Standard_True)
returns Boolean;
---Purpose : Returns True if <name> is present AND set
-- <proper> True (D) : considers this item only
-- <proper> False : if not set and attached to a wild-card,
-- considers this wild-card
CVal (myclass; name : CString) returns CString;
---Purpose : Returns the value of the
-- parameter identified by the string name.
-- If the specified parameter does not exist, an empty
-- string is returned.
-- Example
-- Interface_Static::CVal("write.step.schema");
-- which could return:
-- "AP214"
IVal (myclass; name : CString) returns Integer;
---Purpose : Returns the integer value of
-- the translation parameter identified by the string name.
-- Returns the value 0 if the parameter does not exist.
-- Example
-- Interface_Static::IVal("write.step.schema");
-- which could return: 3
RVal (myclass; name : CString) returns Real;
---Purpose : Returns the value of a static
-- translation parameter identified by the string name.
-- Returns the value 0.0 if the parameter does not exist.
SetCVal (myclass; name : CString; val : CString) returns Boolean;
---Purpose : Modifies the value of the
-- parameter identified by name. The modification is specified
-- by the string val. false is returned if the parameter does not exist.
-- Example
-- Interface_Static::SetCVal
-- ("write.step.schema","AP203")
-- This syntax specifies a switch from the default STEP 214 mode to STEP 203 mode.
SetIVal (myclass; name : CString; val : Integer) returns Boolean;
---Purpose : Modifies the value of the
-- parameter identified by name. The modification is specified
-- by the integer value val. false is returned if the
-- parameter does not exist.
-- Example
-- Interface_Static::SetIVal
-- ("write.step.schema", 3)
-- This syntax specifies a switch from the default STEP 214 mode to STEP 203 mode.S
SetRVal (myclass; name : CString; val : Real) returns Boolean;
---Purpose : Modifies the value of a
-- translation parameter. false is returned if the
-- parameter does not exist. The modification is specified
-- by the real number value val.
Update (myclass; name : CString) returns Boolean;
---Purpose : Sets a Static to be "uptodate"
-- Returns False if <name> is not present
-- This status can be used by a reinitialisation procedure to
-- rerun if a value has been changed
IsUpdated (myclass; name : CString) returns Boolean;
---Purpose : Returns the status "uptodate" from a Static
-- Returns False if <name> is not present
Items (myclass; mode : Integer = 0; criter : CString = "") returns HSequenceOfHAsciiString;
---Purpose : Returns a list of names of statics :
-- <mode> = 0 (D) : criter is for family
-- <mode> = 1 : criter is regexp on names, takes final items
-- (ignore wild cards)
-- <mode> = 2 : idem but take only wilded, not final items
-- <mode> = 3 : idem, take all items matching criter
-- idem + 100 : takes only non-updated items
-- idem + 200 : takes only updated items
-- criter empty (D) : returns all names
-- else returns names which match the given criter
-- Remark : families beginning by '$' are not listed by criter ""
-- they are listed only by criter "$"
--
-- This allows for instance to set new values after having loaded
-- or reloaded a resource, then to update them as required
-- A special class method : initialisation of standard statics
Standards (myclass);
---Purpose : Initializes all standard static parameters, which can be used
-- by every function. statics specific of a norm or a function
-- must be defined around it
