This file defines container classes which represent categories of protocol buffer field types which need extra maintenance. Currently these categories are: - Repeated scalar fields - These are all repeated fields which aren't composite (e.g. they are of simple types like int32, string, etc). - Repeated composite fields - Repeated fields which are composite. This includes groups and nested messages. z petar@google.com (Petar Petrov)� N� c @ sf e Zd Zf Zddd�Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dd� Z dZ dd� Z dd� ZdS )�MappingNc C s" y| | S t k r |S X d S )N)�KeyError)�self�key�default� r � /usr/lib/python3.6/containers.py�getG s z Mapping.getc C s* y | | W n t k r dS X dS d S )NFT)r )r r r r r � __contains__M s zMapping.__contains__c C s t | �S )N)�iter)r r r r �iterkeysU s zMapping.iterkeysc c s x| D ]}| | V qW d S )Nr )r r r r r � itervaluesX s zMapping.itervaluesc c s x| D ]}|| | fV qW d S )Nr )r r r r r � iteritems\ s zMapping.iteritemsc C s t | �S )N)�list)r r r r �keys` s z Mapping.keysc s � fdd�� D �S )Nc s g | ]}|� | f�qS r r )�.0r )r r r � <listcomp>d s z!Mapping.items.<locals>.<listcomp>r )r r )r r �itemsc s z Mapping.itemsc s � fdd�� D �S )Nc s g | ] }� | �qS r r )r r )r r r r g s z"Mapping.values.<locals>.<listcomp>r )r r )r r �valuesf s zMapping.valuesc C s( t |tj�stS t| j� �t|j� �kS )N)� isinstance� collectionsr �NotImplemented�dictr )r �otherr r r �__eq__l s zMapping.__eq__c C s | |k S )Nr )r r r r r �__ne__q s zMapping.__ne__)N)�__name__� __module__� __qualname__� __slots__r r r r r r r r �__hash__r r r r r r r D s r c @ sD e Zd Zf Ze� Zefdd�Zdd� Zdd� Zdd� Z d d d �Z d S ) �MutableMappingc C s< y | | }W n t k r, || jkr(� |S X | |= |S d S )N)r �_MutableMapping__marker)r r r �valuer r r �popy s zMutableMapping.popc C s@ yt t| ��}W n tk r( t�Y nX | | }| |= ||fS )N)�nextr � StopIterationr )r r r$ r r r �popitem� s zMutableMapping.popitemc C s, yx | j � qW W n tk r& Y nX d S )N)r( r )r r r r �clear� s zMutableMapping.clearc O s� t | �dkr tdjt | ����n | s,td��| d }t | �dkrH| d nf }t|t�rrx^|D ]}|| ||< q\W nDt|d�r�x8|j� D ]}|| ||< q�W nx|D ]\}}|||< q�W x |j� D ]\}}|||< q�W d S )N� z8update() takes at most 2 positional arguments ({} given)z,update() takes at least 1 argument (0 given)r � r )�len� TypeError�formatr r �hasattrr r )�args�kwdsr r r r$ r r r �update� s" zMutableMapping.updateNc C s* y| | S t k r$ || |< Y nX |S )N)r )r r r r r r � setdefault� s zMutableMapping.setdefault)N) r r r r �objectr# r% r( r) r2 r3 r r r r r" t s r" c @ sP e Zd ZdZddgZdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dd� Z dS )� BaseContainerzBase container class.�_message_listener�_valuesc C s || _ g | _dS )z� Args: message_listener: A MessageListener implementation.
