Version 5.0 The LEDA User Manual

C& p.third( ) returns the C-component of p. If p is a const-object the
return type is C.
template
bool const three tuple& p == const three tuple& q
equality test for three tuples. Each of the component
types must have an equality operator.
template
int compare(const three tuple& p, const three tuple& q)
template
int Hash(const three tuple& p)
5. Implementation
The obvious implementation is used.
lexicographic ordering for three tuples. Each of the component
types must have a compare function.
hash function for three tuples. Each of the component
types must have a Hash function.
4.20 Four Tuples ( four tuple )
1. Definition
An instance p of type four tuple is a four-tuple (a, b, c, d) of variables of types
A, B, C, and D, respectively.
Related types are two tuple, three tuple, and four tuple.
