class GlobalSection from IGESData
---Purpose : Description of a global section (corresponds to file header)
-- used as well in IGESModel, IGESReader and IGESWriter
-- Warning : From IGES-5.1, a parameter is added : LastChangeDate (concerns
-- transferred set of data, not the file itself)
-- Of course, it can be absent if read from earlier versions
-- (a default is then to be set to current date)
-- From 5.3, one more : ApplicationProtocol (optional)
uses Integer, Character, Real, HAsciiString from TCollection,
XYZ from gp, ParamSet, Check
is
Create returns GlobalSection;
---Purpose : Creates an empty GlobalSection, ready to be filled,
-- Warning : No default value is provided
Init (me : in out; params : ParamSet; ach : in out Check) is static;
---Purpose : Fills GlobalSection from a ParamSet (i.e. taken from file)
-- undefined parameters do not change default values when defined
-- Fills Check about Corrections or Fails
CopyRefs (me : in out) is static;
---Purpose : Copies data referenced by Handle (that is, Strings)
-- usefull to "isolate" a GlobalSection after copy by "="
-- (from a Model to another Model for instance)
Params (me) returns ParamSet is static;
---Purpose : Returns all contained data in the form of a ParamSet
-- Remark : Strings are given under Hollerith form
TranslatedFromHollerith (me; astr : HAsciiString from TCollection)
returns HAsciiString from TCollection is static;
---Purpose : Returns a string withpout its Hollerith marks (nnnH ahead).
-- Remark : all strings stored in GlobalSection are expurged
-- from Hollerith informations (without nnnH)
-- If <astr> is not Hollerith form, it is simply copied
-- -- Specific Queries -- --

--- Purpose: Returns the parameter delimiter character.
EndMark (me) returns Character is static;
---Purpose: Returns the record delimiter character.

---Purpose: Returns the maximum power of a decimal representation of a
-- single-precision floating point number in the sending system.

MaxPower10Double (me) returns Integer is static;
--- Purpose: Returns the maximum power of a decimal representation of a
-- double-precision floating point number in the sending system.
MaxDigitsDouble (me) returns Integer is static;

---Purpose: Returns the unit flag that was used to write the IGES file.
UnitName (me) returns HAsciiString from TCollection is static;
--- Purpose: Returns the name of the unit the IGES file was written in.
LineWeightGrad (me) returns Integer is static;
---Purpose: Returns the maximum number of line weight gradations.
MaxLineWeight (me) returns Real is static;
---Purpose: Returns the of maximum line weight width in IGES file units.
Date (me) returns HAsciiString from TCollection is static;
---Purpose: Returns the IGES file creation date.
Resolution (me) returns Real is static;
---Purpose: Returns the resolution used in the IGES file.
MaxCoord (me) returns Real is static;
---Purpose: Returns the approximate maximum coordinate value found in the model.
HasMaxCoord (me) returns Boolean is static;
---Purpose: Returns True if the approximate maximum coordinate value found in
-- the model is greater than 0.

LastChangeDate (me) returns HAsciiString from TCollection is static;
---Purpose: Returns the date and time when the model was created or last
-- modified (for IGES 5.1 and later).

--- Purpose: Returns True if the date and time when the model was created or
-- last modified are specified, i.e. not defaulted to NULL.

NewDateString (myclass; year,month,day,hour,minut,second : Integer;
mode : Integer = -1)
returns mutable HAsciiString from TCollection;
---Purpose : Returns a string built from year,
-- month, day, hour, minute and second values. The form of the
-- resulting string is defined as follows:
-- - -1: YYMMDD.HHNNSS,
-- - 0: YYYYMMDD.HHNNSS,

-- - YYYY or YY is 4 or 2 digit year,
-- - HH is hour (00-23),
-- - MM is month (01-12),
-- - NN is minute (00-59)
-- - DD is day (01-31),
-- - SS is second (00-59).

---Purpose : Converts the string given in the
-- form YYMMDD.HHNNSS or YYYYMMDD.HHNNSS to either
-- YYMMDD.HHNNSS, YYYYMMDD.HHNNSS or YYYY-MM-DD:HH-NN-SS.
