=head1 NAME

VCL::DataStructure - VCL data structure module

=head1 SYNOPSIS

 my $data_structure;
 eval {
    $data_structure = new VCL::DataStructure({request_id => 66, reservation_id => 65});
 };
 if (my $e = Exception::Class::Base->caught()) {
    die $e->message;
 }

 # Access data by calling method on the DataStructure object
 my $user_id = $data_structure->get_user_id;

 # Pass the DataStructure object to a module
 my $xcat = new VCL::Module::Provisioning::xCAT({data_structure => $data_structure});

 ...

 # Access data from xCAT.pm
 # Note: the data() subroutine is implented by Provisioning.pm which xCAT.pm is
 #       a subclass of
 #       ->data-> could also be written as ->data()->
 my $management_node_id = $self->data->get_management_node_id;

=head1 DESCRIPTION

 This module retrieves and stores data from the VCL database. It provides
 methods to access the data. The database schema and data structures used by
 core VCL code should not be visible to most modules. This module encapsulates
 the data and provides an interface to access it.

=head3 %SUBROUTINE_MAPPINGS

 Data type   : hash
 Description : %SUBROUTINE_MAPPINGS hash maps subroutine names to hash keys.
               It is used by AUTOMETHOD to return the corresponding hash data
               when an undefined subroutine is called on a DataStructure object.

=head2 substitute_string_variables

 Parameters  : $input_string, $variable_identifier_regex (optional)
 Returns     : $string
 Description : Replaces sections of the input string matching
               $variable_identifier_regex with values from the DataStructure
               object. The default pattern used to locate sections to replace
               is:
                  \[[^\]]*\]'
               
               Meaning, all patterns to replace are enclosed in square brackets.
               The text within the brackets must exactly match one of the keys
               of the %SUBROUTINE_MAPPINGS hash defined above. The text must
               begin and end with lowercase letters and contains any number of
               lowercase letters and underscores in between.
               
               Example:
               This is input text for user [user_login_id]'s reservation with
               request/reservation IDs of [request_id]/[reservation_id].
               
               Each section within square brackets gets prepended with 'get_'
               and the resulting string is executed against this DataStructure
               object:
               [user_login_id] --> $self->get_user_login_id(0);

=head2 get_invalid_substitution_identifiers

 Parameters  : $input_string, $variable_identifier_regex (optional)
 Returns     : array
 Description : Checks the input string for invalid substitution identifiers. A
					substitution identifier is valid if it corresponds to one of the
					keys defined in %SUBROUTINE_MAPPINGS or matches one of the
					subroutines explicitly defined in DataStructure.pm. Examples:
               * [user_id]
               * [computer_short_name]
               * [is_parent_reservation]
               
               An identifier is invalid if it contains a typo or doesn't match
               any keys or subroutine names:
               * [usr_id]
               * [foo_bar]
               
               If any invalid subroutines are found, an array is returned
               containing the strings found in the input string which appear to
               be intended as substitution identifiers but don't correlate:
               ('[usr_id]', '[foo_bar]')
					
					Note: This subroutine does not need to be called as an object
					method via $self->data. It's intended to be called from utils.pm.
