NAME
    Data::Seek - Search Complex Data Structures

VERSION
    version 0.05

SYNOPSIS
        use Data::Seek;

        my $hash   = {...};
        my $seeker = Data::Seek->new(data => $hash);
        my $result = $seeker->search('*');

        $result->data;

DESCRIPTION
    Data::Seek is a module for traversing complex data structures. This
    module allows you to select specific node(s) in a hierarchical data
    structure using a criteria. A criteria is an expression consisting of
    one or more criterion. A criterion is the part of the criteria that is
    used to select node(s) and sub-node(s) to be returned in the result.
    Data::Seek is akin to Data::Dpath but with far fewer features, a simpler
    node selection syntax, and a non-recursive approach toward traversal
    which makes Data::Seek extremely fast and efficient. An even better
    reason to use Data::Seek is its ability to throw exception objects which
    explain, in detail, why a search failed. This is very useful internally,
    and externally when processing foreign data structures where you need to
    provide detailed errors explaining how to resolve the missing or
    malformed data nodes. For more information on the underlying concepts,
    please see Data::Seek::Concepts.

ATTRIBUTES
  cache
        $seeker->cache;
        $seeker->cache(1);

    Encode the data structure and cache the result. Allows multiple queries
    to execute faster. Caching is disabled by default.

  data
        $seeker->data;
        $seeker->data(Data::Seek::Data->new(...));

    The data structure to be introspected, must be a hash reference, blessed
    or not, which defaults to or becomes a Data::Seek::Data object.

  ignore
        $seeker->ignore;
        $seeker->ignore(1);

    Bypass exceptions thrown when a criterion finds an unknown or invalid
    node in the data structure.

METHODS
  search
        my @criteria = ('id', 'person.name.*');
        my $result   = $seeker->search(@criteria);

    Prepare a search object to use the supplied criteria and return a result
    object. Introspection is triggered when the result object is enacted.
    See Data::Seek::Search::Result for usage information.
