Derived classes must call ListMixin's __init__() function and implement the following: function _get_single_external(self, i): Return single item with index i for general use. The index i will always satisfy 0 <= i < len(self). function _get_single_internal(self, i): Same as above, but for use within the class [Optional] Note that if _get_single_internal and _get_single_internal return different types of objects, _set_list must distinguish between the two and handle each appropriately. function _set_list(self, length, items): Recreate the entire object. NOTE: items may be a generator which calls _get_single_internal. Therefore, it is necessary to cache the values in a temporary: temp = list(items) before clobbering the original storage. function _set_single(self, i, value): Set the single item at index i to value [Optional] If left undefined, all mutations will result in rebuilding the object using _set_list. function __len__(self): Return the length int _minlength: The minimum legal length [Optional] int _maxlength: The maximum legal length [Optional] type or tuple _allowed: A type or tuple of allowed item types [Optional] r Nc sB t | d�s| j| _t | d�s,| j| _| j| _t� j|i |�� d S )N�_get_single_internal� _set_single) �hasattr�_get_single_externalr �_set_single_rebuildr � _assign_extended_slice_rebuild�_assign_extended_slice�super�__init__)�self�args�kwargs�� __class__� �f/home/gouroczh/virtualenv/test/3.9/lib/python3.9/site-packages/django/contrib/gis/geos/mutable_list.pyr > s zListMixin.__init__c sB t |t�r*� fdd�t|�t� ��� D �S � �|�}� �|�S dS )z-Get the item(s) at the specified index/slice.c s g | ]}� � |��qS r )r ��.0�i�r r r � <listcomp>K s z)ListMixin.__getitem__.<locals>.<listcomp>N)� isinstance�slice�range�indices�len� _checkindexr )r �indexr r r � __getitem__H s � zListMixin.__getitem__c s� t |ttf�std| ��t��}t |t�r>��|�}|g� nt|�|�� � |t� � }� �fdd�t|�D �}��||� dS )z0Delete the item(s) at the specified index/slice.�%s is not a legal indexc 3 s | ]}|� vr�� |�V qd S �N)r r �Z indexRanger r r � <genexpr>` s z(ListMixin.__delitem__.<locals>.<genexpr>N) r �intr � TypeErrorr r r r �_rebuild)r r �origLen�newLen�newItemsr r# r � __delitem__R s �zListMixin.__delitem__c C s> t |t�r| �||� n"| �|�}| �|f� | �||� dS )z-Set the item(s) at the specified index/slice.N)r r � _set_slicer �_check_allowedr �r r �valr r r � __setitem__f s zListMixin.__setitem__c C s | � g | �|��S )z add another list-like objectr �r �otherr r r �__add__p s zListMixin.__add__c C s |� g |�| ��S )z add to another list-like objectr r1 r r r �__radd__t s zListMixin.__radd__c C s | � |� | S )z$add another list-like object to self)�extendr1 r r r �__iadd__x s zListMixin.__iadd__c C s | � t| �| �S ��multiply�r �list�r �nr r r �__mul__} s zListMixin.__mul__c C s | � t| �| �S r7 r9 r; r r r �__rmul__� s zListMixin.__rmul__c C s< |dkr| dd�= n$t | �}t|d �D ]}| �|� q(| S )r8 r N� )r: r r5 )r r< �cacher r r r �__imul__� s zListMixin.__imul__c C sX t |�}t|�D ]:}z| | || k}W n ty> Y dS 0 |s dS qt | �|kS )NF�r r � IndexError�r r2 Zolenr �cr r r �__eq__� s zListMixin.__eq__c C sp t |�}t|�D ]R}z| | || k }W n ty> Y dS 0 |rL| S || | | k r dS qt | �|k S )NTFrB rD r r r �__lt__� s zListMixin.__lt__c C s" d}| D ]}||kr|d7 }q|S )zStandard list count methodr r? r )r r/ �countr r r r rH � s zListMixin.countc C s8 t dt| ��D ]}| | |kr| S qtd| ��dS )zStandard list index methodr z%s not found in objectN)r r � ValueError)r r/ r r r r r � s zListMixin.indexc C s |g| t | �d�< dS )zStandard list append methodN�r �r r/ r r r �append� s zListMixin.appendc C s || t | �d�< dS )zStandard list extend methodNrJ )r �valsr r r r5 � s zListMixin.extendc C s( t |t�std| ��|g| ||�< dS )zStandard list insert methodr!
