API
---

[](#api)

The entry point for accessing I/O collections are the `io.collections.IOCollection` implementations:

- `io.collections.FileCollection` - files in a given filesystem path
- `io.collections.ArchiveCollection` - files inside a XAR archive

To access the files from more than one collection, use the `io.collections.CollectionComposite` class.

Iteration
---------

[](#iteration)

The subpackage `io.collections.iterate` allows iterating I/O collections.

- `io.collections.iterate.IOCollectionIterator` - iterate a given I/O collection, optionally recursive
- `io.collections.iterate.FilteredIOCollectionIterator` - as above, but with an optional filter

### Filters

[](#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
-------

[](#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);
}
```
