ANY | Project-wide universal properties.
This class is an ancestor to all developer-written classes.
ANY inherits from GENERAL, and may be customized for individual
projects or teams.
|
ARGUMENTS | Needed only for ELKS 95 compatibility.
|
BIT_N | Indexed Bit sequences of length `N'. This class is a template,
not a real class; to obtain a meaningful class, replace `N'
with a positive integer throughout.
An INTEGER index can be used to access each bit of the sequence.
The leftmost bit has index 1 and the rightmost bit has index `N'.
Note 1 : corresponding C mapping depends on actual `N' and is
PLATFORM dependant (see class PLATFORM).
When `N' is in range [0 .. Character_bits], C type
is a simple "unsigned char".
When `N' is in range [Character_bits+1 .. Integer_bits],
C type is "unsigned".
When `N' is greater than Integer_bits, C type is C array
of "unsigned" of the form :
"unsigned storage[`N' div Integer_bits]"
The array is obviously big enough to fit with `N'. As
for previous mapping, the left most bit (at index 1 in
Eiffel) is always the left most in C memory.
Note 2 : Eiffel BIT code is portable. Generated C code for class
BIT may not be portable (because sizeof(int) may change).
To produce a portable C code, you can compile your Eiffel
code using a machine with very small sizeof(int). Also note
that doing this may run a little bit slowly.
Also consider class BIT_STRING for very long bit sequences.
|
BIT_STRING | Long and very long bit sequences.
As for the primitive expanded BIT_N type, an INTEGER index can be
used to access each bit of the sequence.
As for BIT_N class, the leftmost bit has index 1 and the
rightmost bit has index `count'.
For short bit sequences (less or equal to 32 or 64), also
consider to use basic BIT_N type.
|
BOOLEAN | Note: An Eiffel BOOLEAN is mapped as a C char or as a Java int.
|
EXCEPTIONS | Facilities for adapting the exception handling mechanism.
This class may be used as ancestor by classes needing its
facilities.
|
FUNCTION | Where B is the base type (i.e. a type of compatible with the target of the delayed call) and where O represents open
arguments (i.e. arguments which are delayed) and where R is for the result type of the delayed call.
|
GENERAL | Platform-independent universal properties. This class is an ancestor to all developer-written classes.
|
HIERARCHIC_GRAPH_NODE |
|
LOADED_HIERARCHIC_GRAPH_NODE |
|
MEMORY | Facilities for tuning up the garbage collection, and
everything about memory control.
|
PLATFORM | This class is ancestor for any user class. This class provides information
as number of bits for basic types and minimum/maximum values.
|
POINTER | References to objects meant to be exchanged with non-Eiffel software.
Note : An Eiffel POINTER is mapped as C type "Void *" or as
Java "java.lang.Object" type.
|
PREDICATE | A PREDICATE is a FUNCTION with a BOOLEAN result type. As in other agent's definitions, B is the base type (i.e. a type of
compatible with the target of the delayed call) and O represents open arguments (i.e. arguments which are delayed).
|
PROCEDURE | Where B is the base type (i.e. a type of compatible with the target of the delayed call) and O represents open
arguments (i.e. arguments which are delayed).
|
ROUTINE | The agent's type hierarchy is composed of the following classes: ROUTINE, PROCEDURE, FUNCTION and PREDICATE.
Where B is the base type (i.e. a type of compatible with the target of the delayed call) and O represents open
arguments (i.e. arguments which are delayed).
|
SAFE_EQUAL | The goal of this class is to share the definition of the feature `safe_equal'.
The feature `safe_equal' compares two arguments of type E, by calling `is_equal' only if
both arguments have the `same_dynamic_type'.
|
STRING_HANDLER | Inherit this class if you need access to STRING internal storage.

|
SYSTEM | This expanded class allow to execute system command
and to get/set environment variables.
|
TUPLE |
|
WEAK_REFERENCE | Weak reference to an object.
This kind of reference does not prevent the object from being
reclaimed by the garbaged collector (in which case item returns Void).
Item makes it possible to get (a strong reference to) the object.
Inheriting from this class is prohibited.
This class works with compile_to_c, but NOT with compile_to_jvm.
|
Provides the very basic functionalities the compiler could not dream of working without.
