The FloatNamedArraylist class is nearly identical to the NamedArraylist class. The significant difference is that instead of subscript names for items as in the NamedArraylist class, the item subscripts in a FloatNamedArraylist object are numeric values. These numeric subscripts are basically like the Model 204 Float datatype, and FloatNamedArraylist items are stored in numeric order by subscript, whereas NamedArraylist items are stored by item name in EBCDIC order.

About the GenericNamedArraylist class

The FloatNamedArraylist class extends the system GenericNamedArraylist class, so many of the methods available in the FloatNamedArraylist class are documented as belonging to the GenericNamedArraylist class. Any method available in the GenericNamedArraylist class is also available in the FloatNamedArraylist class. The other classes that extend the GenericNamedArraylist class are the NamedArraylist class and the UnicodeNamedArraylist class.

Example

The following request demonstrates the numerically ordered result produced by a FloatNamedArraylist but not by a NamedArraylist:

    b
 
    %x  is collection namedArraylist of string len 32
    %y  is collection floatNamedArraylist of string len 32
    %i  is float
 
    %x = new
    %x(7) = 'seven'
    %x(38) = 'thirty-eight'
    %x(110) = 'one-hundred-ten'
 
    %y = new
    %y(7) = 'seven'
    %y(38) = 'thirty-eight'
    %y(110) = 'one-hundred-ten'
 
    for %i from 1 to %x:count
       print %x:nameByNumber(%i) and %x:itemByNumber(%i)
    end for
 
    for %i from 1 to %y:count
       print %y:nameByNumber(%i) and %y:itemByNumber(%i)
    end for
 
    end

The request prints:

    110 one-hundred-ten
    38 thirty-eight
    7 seven
    -----
    7 seven
    38 thirty-eight
    110 one-hundred-ten

For background information about collections and about declaring collection object variables, see "Collections". See also "Coding considerations for collections".

The individual FloatNamedArraylist methods are described in the following subsections. In the method templates, %fnamrayl is used to represent the object to which the method is being applied, sometimes called the “method object” or the “method FloatNamedArraylist.” Additional conventions are described in "Notation conventions for methods".
