API
The entry point for accessing I/O collections are the io.collections.IOCollection
implementations:
io.collections.FileCollection
- files in a given filesystem pathio.collections.ArchiveCollection
- files inside a XAR archive
To access the files from more than one collection, use the io.collections.CollectionComposite
class.
Iteration
The subpackage io.collections.iterate
allows iterating I/O collections.
io.collections.iterate.IOCollectionIterator
- iterate a given I/O collection, optionally recursiveio.collections.iterate.FilteredIOCollectionIterator
- as above, but with an optional filter
Filters
The following filters are available:
Date-based:
io.collections.iterate.AccessedAfterFilter(util.Date $date)
io.collections.iterate.AccessedBeforeFilter(util.Date $date)
io.collections.iterate.CreatedAfterFilter(util.Date $date)
io.collections.iterate.CreatedBeforeFilter(util.Date $date)
io.collections.iterate.ModifiedAfterFilter(util.Date $date)
io.collections.iterate.ModifiedBeforeFilter(util.Date $date)
Size-based:
io.collections.iterate.SizeEqualsFilter(int $compare)
io.collections.iterate.SizeBiggerThanFilter(int $limit)
io.collections.iterate.SizeSmallerThanFilter(int $limit)
Name-based:
io.collections.iterate.ExtensionEqualsFilter(string $compare)
io.collections.iterate.NameEqualsFilter(string $compare)
io.collections.iterate.NameMatchesFilter(string $pattern)
io.collections.iterate.UriMatchesFilter(string $pattern)
Type-based:
io.collections.iterate.CollectionFilter()
To combine filters, use the util.Filters
class.
Example
This finds all JPEG files inside the directory /home/thekid/multimedia
:
use io\collections\FileCollection; use io\collections\iterate\{FilteredIOCollectionIterator, ExtensionEqualsFiler}; use util\cmd\Console; use util\Filters; $iterator= new FilteredIOCollectionIterator( new FileCollection('/home/thekid/multimedia'), Filters::allOf([new ExtensionEqualsFilter('.jpg'), new ExtensionEqualsFilter('.JPG')]), true ); foreach ($iterator as $file) { Console::writeLine($file); }
