This module is meant to be the definitive implementation of iterators, as popularized by Mark Jason Dominus's lectures and recent book (*Higher Order Perl*, Morgan Kauffman, 2005). An "iterator" is an object, represented as a code block that generate...

UR::Iterator - API for iterating through data River stage one • 3 direct dependents • 4 total dependents

UR::Iterator instances implement the iterator pattern. These objects can be created with either a list of values, or by applying a mapping function to another iterator. UR::Iterator instances are normal Perl object references, not UR-based objects. T...

Iterator::DBI - An iterator for returning DBI query results. River stage one • 1 direct dependent • 1 total dependent

This module contains a function to return an iterator (see the Iterator module) that returns the rows of a database query, one at a time. This is marginally more useful than simply calling prepare and execute, and then repeatedly calling fetchrow_has...

Ace::Iterator - Iterate Across an ACEDB Query River stage one • 1 direct dependent • 2 total dependents

The Ace::Iterator class implements a persistent query on an Ace database. You can create multiple simultaneous queries and retrieve objects from each one independently of the others. This is useful when a query is expected to return more objects than...

Iterator::File - A file iterator, optionally stateful and verbose. River stage one • 1 direct dependent • 1 total dependent

"Iterator_File" is an attempt to take some repetition & tedium out of processing a flat file. Whenever doing so, I found myself adapting prior scripts so that processes could be resumed, emit status, etc. Hence an itch (and this module) was born....

Iterator::Util - Essential utilities for the Iterator class. River stage two • 2 direct dependents • 71 total dependents

This module implements many useful functions for creating and manipulating iterator objects. An "iterator" is an object, represented as a code block that generates the "next value" of a sequence, and generally implemented as a closure. For further in...

Iterator::Misc - Miscellaneous iterator functions. River stage one • 1 direct dependent • 1 total dependent

This module contains miscellaneous iterator utility functions that I think aren't as broadly useful as the ones in Iterator::Util. They are here to keep the size of Iterator::Util down. For more information on iterators and how to use them, see the I...

DBIx::Iterator - Query your database using iterators and save memory River stage one • 1 direct dependent • 1 total dependent

Iterators are a nice way to perform operations on large datasets without having to keep all of the data you're working on in memory at the same time. Most people have experience with iterators already from working with filehandles. They are basically...

Iterator::Files - Iterate through the contents of a list of files River stage one • 2 direct dependents • 2 total dependents

Iterator::Files can be used to retrieve the contents of a series of files as if it were one big file, in the style of the "<>" (Diamond) operator. Just like "<>" it returns the records of all files, one by one, as if it were one big happy file. In-pl...

Iterator::Paged - Simple iterator with events for accessing more records. River stage one • 2 direct dependents • 3 total dependents

Iterator::Paged provides a simple (subclassable) iterator that will attempt to fetch the next "page" of results when the current set is exhausted. For example, suppose you have an iterator for results on that fetches the first page of resu...

SPOPS::Iterator - Class to cycle through results and return SPOPS objects River stage one • 2 direct dependents • 2 total dependents

One of the problems with current SPOPS implementations is that retrieving groups of objects is an all-or-nothing affair -- you get a list with all instantiated objects or you do not retrive them in the first place. This can be quite memory intensive,...
