Constructor Details

#initialize(node, opts = {}) ⇒ Entity

The Entity class provides a base class implementation for building API modules. The Entity class is typcially not instantiated directly but serves as a super class with convenience methods used to work with the node.

Parameters:

  • :node (Node) —

    This should be an instance of Rbeapi::Client::Node that is used to send and receive eAPI messages

end

Instance Attribute Details

#config ⇒ String (readonly)

Returns the running configuration from the node instance. This is a convenience method to easily access the current running config from an API module

Returns:

  • (String) —

    The current running-config from the node

Class Method Details

.instance(node) ⇒ Object

The instance class method is used to create a new instance of the object. It works in conjunction with the Node.api loader method to make it easy to load classes derived from Entity

Parameters:

  • :node (Node) —

    An instance of Rbeapi::Client::Node used to send and receive eAPI messages

def self.instance(node)
  new(node)
end

Instance Method Details

#configure(commands) ⇒ Boolean

Method called to send configuration commands to the node. This method will send the commands to the node and rescue from CommandError or ConnectionError.

Parameters:

  • :commands (String, Array) —

    The commands to send to the node over the API connection to configure the system

Returns:

  • (Boolean) —

    Returns True if the commands were successful or returns False if there was an error issuing the commands on the node. Use error to further investigate the cause of any errors

    return false
  end
end

#get_block(text) ⇒ Object

Returns a block of configuration from the current running config as a string. The argument is used to search the config and return the text along with any child configuration statements.

Parameters:

  • :text (String) —

    The text to be used to find the parent line in the nodes configuration.
