NAME

Bio::Tools::EUtilities::Summary::DocSum

SYNOPSIS

# Implement ItemContainerI

# $foo is any ItemContainerI (current implementations are DocSum and Item itself)

while (my $item = $foo->next_Item) { # iterate through contained Items
   # do stuff here
}

@items = $foo->get_Items;  # all Items in the container (hierarchy intact)
@items = $foo->get_all_Items;  # all Items in the container (flattened)
@items = $foo->get_Items_by_name('bar'); # Specifically named Items
($content) = $foo->get_contents_by_name('bar'); # content from specific Items
($type) = $foo->get_type_by_name('bar'); # data type from specific Items

DESCRIPTION

This is the basic class for Document Summary data from NCBI eUtils, returned from esummary. This implements the simple ItemContainerI interface.

NAME

Bio::Tools::EUtilities::Summary::DocSum - data object for document summary data from esummary

           implementations of get_ids(). To retrieve the single DocSum ID
           use get_id()

Title    : get_id
Usage    : my ($id) = $item->get_id;
Function : returns UID of record
Returns  : integer
Args     : none

Title    : next_Item
Usage    : while (my $item = $docsum->next_Item) {...}
Function : iterates through Items (nested layer of Item)
Returns  : single Item

Returns  : array of Items
Args     : none
Note     : items are added top-down (similar order to using nested calls)
           in original list order.
