NAME

Data::Domain::Dependencies

DESCRIPTION

Provides functions and objects to let Data::Domain use the same functions as Params::Validate.

SYNOPSIS

This creates a domain which, when passed a hashref, to inspect, will check that it contains at least one of an 'alpha' or 'beta' key, or both of 'foo' and 'bar'.

  use Data::Domain::Dependencies qw(:all);

  my $domain = Dependencies(
    any_of(
      qw(alpha beta),
      all_of(qw(foo bar))
    )
  );

  my $errors = $domain->inspect(\%somehash);

SUBROUTINES and EXPORTS

Nothing is exported by default, but you can export any of the *_of functions of Params::Validate::Dependencies, and the 'Dependencies' function. They are all available under the 'all' tag.

Dependencies

This takes a code-ref argument. That code-ref should take a hash-ref as its argument and return true if the hash-ref passes validation, false otherwise.

'Dependencies' will return an object wrapped around that code-ref whoise 'inspect' method will, if the code-ref returns true, return nothing, or if false, return an error.

new

'Dependencies' above is really just a thin wrapper around this constructor, which simply takes a code-ref argument. You are encouraged to not call this directly.

BUGS, LIMITATIONS, and FEEDBACK

I like to know who's using my code. All comments, including constructive criticism, are welcome.

Please report any bugs either by email or using http://rt.cpan.org/ or at https://github.com/DrHyde/perl-modules-Params-Validate-Dependencies/issues.

Bug reports should contain enough detail that I can replicate the problem and write a test. The best bug reports have those details in the form of a .t file. If you also include a patch I will love you for ever.
