# Algorithm::Dependency::Source::HoA(3pm)

Source for a HASH of ARRAYs

## NAME

Algorithm::Dependency::Source::HoA - Source for a HASH of ARRAYs

## SYNOPSIS

```
  # The basic data structure
  my $deps = {
      foo => [ 'bar', 'baz' ],
      bar => [],
      baz => [ 'bar' ],
      };

  # Create the source from it
  my $Source = Algorithm::Dependency::Source::HoA->new( $deps );
```

## DESCRIPTION

`"Algorithm::Dependency::Source::HoA"` implements a source where the items names are provided in the most simple form, a reference to a `"HASH"` of `"ARRAY"` references.

## METHODS

This documents the methods differing from the ordinary Algorithm::Dependency::Source methods.

### new $filename

When constructing a new `"Algorithm::Dependency::Source::HoA"` object, an argument should be provided of a reference to a HASH of ARRAY references, containing the names of other HASH elements.

Returns the object, or `"undef"` if the structure is not correct.
