.SH NAME
D__repetition \- Interface for class D__repetition

.SH DESCRIPTION
D__repetition is a class template used to define repetition classes.
D__repetition is defined as an abstract class template, which means
its methods are not fully implemented. To define a repetition class, a
user must inherit from an instantiation of one of the concrete
subclasses of D__repetition, e.g., D__linked_list.

Assuming template<class R> class D__repetition, the following methods
are available to users of class D__repetition.

.TP 10
.I virtual D__repetition<R>* add( R* ob ) = 0;
Returns a new repetition with ob added.
.TP
.I int empty();
Returns TRUE or FALSE, depending on whether the repetition has size 0 or not.
.TP
.I virtual char* g_code( int&,ofstream& ) const = 0;
.TP
.I virtual D__universal* g_copy() const = 0;
.TP
.I virtual void g_draw() = 0;
.TP
.I virtual int g_equal( D__universal* ) const = 0;
.TP
.I virtual D__repetition<R>* join( D__repetition<R>* other );
Returns a new repetition that contains all the the elements of other
and the current repetition.
.TP
.I virtual R* member( R* ob ) = 0;
If ob is contained in the repetition, return ob, otherwise NULL.
.TP
.I virtual D__repetition<R>* member_if( R* ob,int (*compare)(R*,R*) ) = 0;
Returns a repetition containing all elements e for which compare( e,ob
) returns TRUE.
.TP
.I virtual D__repetition<R>* member_if( int (*compare)(R*) ) = 0;
Returns a repetition containing all elements e for which compare( e )
returns TRUE.
.TP
.I virtual D__repetition<R>* remove( R* ob );
Returns a new repetition with ob removed.
.TP
.I virtual D__repetition<R>* remove_if( R* ob,int (*compare)(R*,R*) );
Returns a new repetition with every element e removed such that
compare( e,ob ) returns TRUE.
.TP
.I virtual int size() = 0;
Returns the number of elements in the repetition.
