Eiffel 音标拼音: ['ɑɪfəl]
Eiffel n 1 :
French engineer who constructed the Eiffel Tower (
1832 -
1923 ) [
synonym : {
Eiffel }, {
Alexandre Gustave Eiffel }]
An {object -oriented } language produced by {Bertrand
Meyer } in 1985 . Eiffel has {classes } with {multiple
inheritance } and {repeated inheritance }, {deferred class }es
(like {Smalltalk }'s {abstract class }), and {clusters } of
classes . Objects can have both {static types } and {dynamic
types }. The dynamic type must be a descendant of the static
(declared ) type . {Dynamic binding } resolves {multiple
inheritance } clashes . It has flattened forms of classes , in
which all of the inherited features are added at the same
level and {generic class }es parametrised by type .
Other features are {persistent objects }, {garbage collection },
{exception } handling , {foreign language interface }. Classes
may be equipped with {assertions } (routine preconditions and
postconditions , class {invariants }) implementing the theory of
"{Design by Contract }" and helping produce more reliable
software .
Eiffel is compiled to {C }. It comes with libraries containing
several hundred classes : data structures and {algorithms }
(EiffelBase ), graphics and user interfaces (EiffelVision ) and
language analysis (EiffelLex , EiffelParse ).
The first release of Eiffel was release 1 .4 , introduced at the
first {OOPSLA } in October 1986 . The language proper was first
described in a University of California , Santa Barbara report
dated September 1985 .
Eiffel is available , with different libraries , from several
sources including {Interactive Software Engineering }, USA (ISE
Eiffel version 3 .3 ); Sig Computer GmbH , Germany (Eiffel /S );
and {Tower , Inc .}, Austin (Tower Eiffel ).
The language definition is administered by an open
organisation , the Nonprofit International Consortium for
Eiffel (NICE ). There is a standard kernel library .
An {Eiffel source checker } and compiler {front -end } is
available .
Latest version : 4 .2 , as of 1998 -10 -28 .
Latest version : ISE Eiffel version 3 .3 .
