Iterator

SOJO is a Java framework that converts JavaBeans (complex Java-Object graphs) to a simplified representation, so that handling access to JavaBeans properties is easy and uniform. SOJO framework is meant to compliment POJOs in cases where object orientation is not supported or is not the best...

SPOPS::Iterator is a class to cycle through results and return SPOPS objects. SYNOPSIS my $iter = $spops_class->fetch_iterator({ where => last_name like ?, value => [ smi% ] }); while ( $iter->has_next ) { my $object = $iter->get_next; print "Object ID: ", $object->id, " at position: ",...

Iterator::Misc Perl module package contains miscellaneous iterator functions. SYNOPSIS use Iterator::Misc; # Permute the elements of a list: $iter = ipermute (@items); # Select only every nth value of an iterator $iter = inth ($n, $another_iterator); # Randomly select iterator values...

Iterator::IO is a Perl module with filesystem and stream iterators. SYNOPSIS use Iterator::IO; # Return the names of files in a directory (except . and ..) $iter = idir_listing ($path); # Return all the files in a directory tree, one at a time. # Like File::Find, in slow motion. $iter...

DateTime::Event::Cron is a DateTime extension for generating recurrence sets from crontab lines and files. SYNOPSIS use DateTime::Event::Cron; # DateTime::Set construction from crontab line $crontab = */3 15 1-10 3,4,5 */2; $set = DateTime::Event::Cron->from_cron($crontab); $iter =...

XML::NodeFilter is a generic XML::NodeFilter Class. SYNOPSIS use XML::NodeFilter; my $filter = XML::NodeFilter->new(); $your_iterator->set_filter( $filter ); "Filters are objects that know how to "filter out" nodes. If a NodeIterator or a TreeWalker is given a NodeFilter, it applies the...

This function provides a simple iterator for the lines of a file-like object. (It also provides a flag for removing/retaining trailing newlines.) I ran into the problem a number of times that I wanted to read-in a very large file-like object (say a GB or two) line by line. This is a problem for...

This script provides a class called LineIterator that iterates over every line in a list of files, performing the basic functionality as fileinput module in the standard library (which mimics Perl's operator). Basically acts as a simple and methodical way to iterate over every line in a list of...

Tiny Vector and Matrix template library uses Meta Templates (MT) and Expression Templates (ET) to evaluate results at compile time -- which makes it fast for low order (tiny) systems."Tiny" is a subjective term, but typically means vectors and matrices of size ten (10) or less.Features: - STL...

This script presents a general purpose file object iterator cum file object proxy class.It provides a class that gives several iterator functions to read a text file by characters, words, lines, paragraphs or blocks. It also acts as a proxy for the wrapped file object. ts as a pOne way to do it...

This script shows an implementation of isplit, a function that splits iterators into two equal ones, which return similar values, but are exact copies of one another.

This script is an iterator that can be used to walk through directories.This class is intended to provide an iterator version of the os.listdir function. The interesting property of the iterator is that you can control if you want a deep iteration of directories with the 'deep' member.After...

This script allows you to choose a random object from an iterated list. Each item has an equal chance of being picked. The iterator is processed only once, and only the selected items are stored, making this function memory efficid only thbr />

The basic iterator for a list doesn't allow one to skip forward (except with "continue"), or backward (at all), nor does it behave well if the list is modified while it is being traversed. This script is NOT the be-all and end-all of improved iterators, but it gives a few ideas of how a better...

Merging two sorted iterators script provides a mergeiter() function that can merge two iterators into a single iterator. It uses generators, and guarantees constant memory use.


Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script implements the three standard relational join algorithms: nested loops join, hash join, and merge join, using the iterator algebra support in Python.This script also presents code that can be used for inner join, left outer join, full outer join, and semijoins. The nested loops join...
