Causes the receiver class to inherit the instance and class methods of
the class object
classobj. The
classpos is a class object
that specifies the position of the new superclass in the list of superclasses.
(You can use the
superClasses
method to return the immediate superclasses.)
The new superclass is inserted in the search order after the specified
class. If the
classpos class is not found in
the set of superclasses, an error is raised. If you do not specify
classpos, the new superclass
is added to the end of the superclasses list.
Inherited methods can take precedence only over methods defined at or
above the base class of the
classobj in the
class hierarchy. Any subsequent change to the instance methods of
classobj takes immediate effect
for all the classes that inherit from it.
The new superclass
classobj must be
created with the
MIXINCLASS
option of the
::CLASS directive or the
mixinClass method and the base class
of the
classobj must be a direct superclass
of the receiver object. The receiver must not already descend from
classobj in the class
hierarchy and vice versa.
The method search order of the receiver class after
inherit is the same
as before
inherit, with the addition of
classobj and its superclasses
(if not already present).
You cannot change the classes that Rexx provides by sending
inherit messages.
The
inherit
method is a protected method.
