NAME

Net::Radio::oFono::Helpers::Container - simple container providing typical container functions

DESCRIPTION

This package implements a class which will act as a container for items of any type. The container can be forced to accept only classes of a specific type.

INHERITANCE

Net::Radio::oFono::Helpers::Container

METHODS

new

Instantiates a new container object.

Parameters:

All parameters are optional.

array-ref

Reference to an array for managing items. Use with caution, it can be dangerous when two containers access the same list.

class-name

Name of classes to restrict the type which can be added. Adding items which are not of specified type (or derived), an exception is thrown via Assert.

add

Adds a new item to the container.

Parameters:

item

List of items to add to the container.

remove

Removes an item from the container.

Parameters:

item

Item to remove from the container.

Returns:

The removed element in scalar mode and and array containing the removed element at position 0 and it's index in the managed list at index 1 in array mode.

contains

Returns whether this container manages specified item or not, compared by the item address (Scalar::Util::refaddr).

Parameters:

item

The item to search for being in this container or not

Returns:

Boolean value - either it's in there or not.

clear

Clears this container, resets iterator. For each item, explicitely remove is called for clearing.

is_empty

Returns true when the container is empty - false otherwise.

n_elements

Returns the number of elements contained.

for_each

Calls given sub for each item once, with the item as only argument. It's not recommended to use this method - it's here for compatibility reasons only. A better way to do sth. for each item is to use the iterator operators.
