Generic -- formal Less returns the result of comparing the elements designated by the -- indexes, and generic formal Swap exchanges the designated elements. generic type Index_Type is (<>); with function Less (Left, Right : Index_Type) return Boolean is <>; with procedure Swap (Left, Right : Index_Type) is <>; procedure Ada.Containers.Generic_Anonymous_Array_Sort (First, Last : Index_Type'Base); pragma Pure (Ada.Containers.Generic_Anonymous_Array_Sort); -- Reorders the elements of Container such that the elements are sorted -- smallest first as determined by the generic formal "<" operator provided. -- Any exception raised during evaluation of "<" is propagated. -- -- The actual function for the generic formal function "<" is expected to -- return the same value each time it is called with a particular pair of -- element values. It should not modify Container and it should define a -- strict weak ordering relationship: irreflexive, asymmetric, transitive, and -- in addition, if x < y for any values x and y, then for all other values z, -- (x < z) or (z < y). If the actual for "<" behaves in some other manner, -- the behavior of the instance of Generic_Anonymous_Array_Sort is -- unspecified. The number of times Generic_Anonymous_Array_Sort calls "<" is -- unspecified.
