generic class HArray1 from PCollection  (Item as Storable) 
inherits Persistent

	---Purpose: The class HArray1 represents unidimensionnal 
	-- array of fixed size known at run time. 
	-- The range of the index is user defined. 
	--  Warning: Programs clients of such class must be independent
	-- of the range of the first element. Then, a C++ for
	-- loop must be written like this
	--     for (i = A->Lower(); i <= A->Upper(); i++)
uses 
    Integer from Standard,
    Address from Standard
    
raises 
    OutOfRange from Standard,
    RangeError from Standard
    
    class FieldOfHArray1 instantiates VArray from DBC (Item);
    
is


	Create (Low, Up: Integer from Standard) returns mutable HArray1
		raises RangeError from Standard;
		---Purpose: Creates an array of lower bound <Low> and 
                -- upper bound <Up>. Range error is raised 
                -- when <Up> is less than <Low>.

	Create (Low, Up: Integer from Standard ; V : Item) 
                returns mutable HArray1
		raises RangeError from Standard;
		---Purpose: Creates an array of lower bound <Low> and 
                -- upper bound <Up>. Range error is raised 
                -- when <Up> is less than <Low>.
		-- The Array is initialized with V

	Length (me) returns Integer from Standard
		is static ;
		---Purpose:  Returns the number of elements of <me>.
                ---Level: Public
    	    	---C++: inline

	Lower (me) returns Integer from Standard
		is static ;
		---Purpose: Returns the lower bound.
                ---Level: Public
    	    	---C++: inline

	SetValue (me : mutable; Index: Integer from Standard; Value: Item) 
		---Purpose: Assigns Value to the Index-th element of this array.
    	    	-- Example
    	    	-- PCollection_HArray1
    	    	-- myTable(1,100);
    	    	-- myTable->SetValue(3, 1551);
    	    	-- assert (myTable(3) == 1551);
    	    	-- Exceptions
    	    	-- Standard_OutOfRange if Index is not within the bounds of this array
		raises OutOfRange from Standard
		is static ;
		---Purpose: Set the <Index>th element of the array to <Value>.
                ---Level: Public

	Upper (me) returns Integer from Standard
		is static ;
		---Purpose: Returns the upper bound.
                ---Level: Public
    	    	---C++: inline

	Value (me; Index: Integer from Standard) returns any Item
		raises OutOfRange from Standard
		is static;
		---Purpose: Returns the value of the <Index>th element of the array.
              	--  Example
    	    	-- PCollection_HArray1
    	    	-- myTable(1,100);
    	    	-- myTable->SetValue(3, 1551);
    	    	-- Standard_Integer myItem =
    	    	-- myTable->Value(3);
    	    	-- Exceptions
    	    	-- Standard_OutOfRange if Index is not within the bounds of this array. 
    
    ShallowCopy(me) 
                returns mutable like me 
                is redefined;
                ---Purpose: Returns a new array containing a copy
   	    	-- of the values (of the elements) in this array.


    	ShallowDump (me; s: in out OStream) 
                is redefined;
                ---Level: Advanced
    	    	---C++: function call

    	Field (me)returns FieldOfHArray1 
                ---Level: Internal
                is private;
   	    	---Purpose: Private method that returns the field Data.
        
        Datas(me) returns Address
                ---Level: Internal
