class ByteArray from TDataStd inherits Attribute from TDF

    ---Purpose: An array of Byte (unsigned char) values.

uses 
    GUID                from Standard,
    Attribute           from TDF,
    Label               from TDF,
    RelocationTable     from TDF, 
    DeltaOnModification from TDF,

    ---Purpose: Static methods

    GetID (myclass)   
    ---C++: return const & 
    ---Purpose: Returns an ID for array.
    returns GUID from Standard;

    	 label : Label from TDF; 
    	 lower, upper : Integer from Standard; 
    	 isDelta : Boolean from Standard = Standard_False)
    ---Purpose: Finds or creates an attribute with the array. 
    -- If <isDelta> == False, DefaultDeltaOnModification is used.     
    -- If attribute is already set, all input parameters are refused 
    -- and the found attribute is returned.

    Init (me : mutable;

    ---Purpose: Initialize the inner array with bounds from <lower> to <upper>  

    SetValue (me : mutable; 
    	      index :Integer from Standard; 
    	      value : Byte 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 Byte from Standard;

    Lower (me) 
    ---Purpose: Returns the lower boundary of the array.
    returns Integer from Standard;      

    Upper (me) 
    ---Purpose: Returns the upper boundary of the array.
    returns Integer from Standard;
    
    Length (me) 
    ---Purpose: Returns the number of elements in the array.
    returns Integer from Standard;

    ---Purpose: Sets the inner array <myValue>  of the attribute to 
    -- <newArray>. If value of <newArray> differs from <myValue>, Backup performed 
    -- and myValue refers to new instance of HArray1OfInteger 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).
