Math::NumSeq::Base::IteratePred -- iterate by searching with pred()
package MyNumSeqSubclass; use Math::NumSeq; use Math::NumSeq::Base::IteratePred; @ISA = ('Math::NumSeq::Base::IteratePred', 'Math::NumSeq'); sub ith { my ($self, $i) = @_; return something($i); }
This is a multi-inheritance mix-in providing the following methods
rewind() next()
They iterate by calling pred() to search for values in the sequence, starting at values_min() and stepping by 1 each time.
pred()
values_min()
This is a handy way to implement the iterating methods for a NumSeq if there's no easy way to step or random access for values, only test a condition.
NumSeq
The current implementation is designed for infinite sequences, it doesn't check for a values_max() limit.
values_max()
