Class that reads CLI output and parses into tabular format. Supports the use of index files to map TextFSM templates to device/command output combinations and store the data in a TextTable. Is the glue between an automated command scraping program (such as RANCID) and the TextFSM output parser. � )�absolute_import)�division)�print_function)�unicode_literalsN)�object)�str)�copyable_regex_object)� texttablec @ s e Zd ZdZdS )�ErrorzBase class for errors.N��__name__� __module__� __qualname__�__doc__� r r ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/textfsm/clitable.pyr , s r c @ s e Zd ZdZdS )�IndexTableErrorzGeneral INdexTable error.Nr r r r r r 0 s r c @ s e Zd ZdZdS )� CliTableErrorzGeneral CliTable error.Nr r r r r r 4 s r c @ sL e Zd ZdZddd�Zdd� Zdd� Zd d � Zdd d �Zd d� Z dd� Z dS )� IndexTableak Class that reads and stores comma-separated values as a TextTable.

Reads an index file and uses it to map command strings to templates. It then uses TextFSM to parse the command output (raw) into a tabular format. The superkey is the set of columns that contain data that uniquely defines the row, the key is the row number otherwise. This is typically gathered from the templates 'Key' value but is extensible. Attributes: raw: String, Unparsed command string from device/command. index_file: String, file where template/command mappings reside. template_dir: String, directory where index file and templates reside. c s � fdd�}|S )zSynchronisation decorator.c s> | j �� z"� | g|�R i |��W | j �� S | j �� 0 d S )N)�_lock�acquire�release)Zmain_obj�args�kwargs��funcr r �Wrapper� s �z&CliTable.synchronised.<locals>.Wrapperr )r< r= r r; r � synchronised� s zCliTable.synchronisedNc s: t t| ��� t� | _d| _|| _|| _|r6| �|� dS )z�Create new CLiTable object.

Supplements the Keys already extracted from the FSM template. Useful when adding new columns to existing tables. Note: This will impact attempts to further 'extend' the table as the superkey must be common between tables for successful extension.
