class RealArray from TDataStd inherits Attribute from TDF
---Purpose: A framework for an attribute composed of a real number array.
uses
HArray1OfReal from TColStd,
GUID from Standard,
Attribute from TDF,
Label from TDF,
DeltaOnModification from TDF,
RelocationTable from TDF
is
---Purpose: class methods
-- =============
GetID (myclass)
---C++: return const &
---Purpose: Returns the GUID for arrays of reals.
returns GUID from Standard;
Set (myclass; label : Label from TDF; lower, upper : Integer from Standard;
isDelta : Boolean from Standard = Standard_False)
---Purpose: Finds or creates on the <label> a real array attribute
-- with the specified <lower> and <upper> boundaries.
-- If attribute is already set, all input parameters are refused and the found
-- attribute is returned.
returns RealArray from TDataStd;
---Category: RealArray methods
-- ===============
Init(me : mutable; lower, upper : Integer from Standard);
---Purpose: Initialize the inner array with bounds from <lower> to <upper>
SetValue (me : mutable; Index :Integer from Standard; Value : Real from Standard);
---Purpose: Sets the <Index>th element of the array to <Value>
Value (me; Index : Integer from Standard)
---Purpose: Return the value of the <Index>th element of the array
--
---C++: alias operator ()
returns Real from Standard;
Lower (me) returns Integer from Standard;
---Purpose: Returns the lower boundary of the array.
Upper (me) returns Integer from Standard;
---Purpose: Returns the upper boundary of the array.
Length (me) returns Integer from Standard;
---Purpose: Returns the number of elements of the array of reals
-- in terms of the number of elements it contains.
ChangeArray(me : mutable; newArray : HArray1OfReal from TColStd;
isCheckItems : Boolean = Standard_True);
---Purpose: Sets the inner array <myValue> of the RealArray attribute
-- to <newArray>. If value of <newArray> differs from <myValue>,
-- Backup performed and myValue refers to new instance of HArray1OfReal
-- that holds <newArray> values
-- If <isCheckItems> equal True each item of <newArray> will be checked with each
-- item of <myValue> for coincidence (to avoid backup).
Array(me) returns HArray1OfReal from TColStd;
---Purpose: Returns the handle of this array of reals.
---C++: inline
---C++: return const
GetDelta(me) returns Boolean from Standard;
---C++: inline
SetDelta(me : mutable; isDelta : Boolean from Standard);
---C++: inline
---Purpose: for internal use only!
RemoveArray(me : mutable) is private;

-- =========================
Create

Restore (me: mutable; With : Attribute from TDF);
NewEmpty (me)
returns mutable Attribute from TDF;
