Math::NumSeq::Base::IterateIth -- iterate by calling ith() successively
package MyNumSeqSubclass; use Math::NumSeq; use Math::NumSeq::Base::IterateIth; @ISA = ('Math::NumSeq::Base::IterateIth', 'Math::NumSeq'); sub ith { my ($self, $i) = @_; return something($i); }
This is a multi-inheritance mix-in providing the following methods
rewind() next() seek_to_i()
They iterate simply by calling ith() to get each successive value, starting from i_start().
ith()
i_start()
This is a handy way to implement the iterating methods for a NumSeq if there's nothing special that next() can do beyond a full ith() calculation.
NumSeq
next()
If ith() returns undef then that's taken to be the end of the sequence and next() returns no values.
undef
