source code

update(self, key, value)
Update the value of the parameter in the cache

source code

set(self, key, value)

Method Details

init(self)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

set_notifier(self, notifier)

source code

Notifier implements any parameter subscription logic. The notifier should be a function that takes in a key and value that represents a parameter update. Notifier is called under lock and thus must not implement any lengthy computation.

update(self, key, value)

source code

Update the value of the parameter in the cache

Parameters:

key (str) - parameter key
value (str) - parameter value

set(self, key, value)

source code

Set the value of the parameter in the cache. This is a prerequisite of calling update().

Parameters:

key (str) - parameter key
value (str) - parameter value

get(self, key)

source code

Parameters:

key (str) - parameter key

Returns:

Current value for parameter
