getExtensionPrefs

Creates an extension-specific preferences manager using the prefix given. A . character will be appended to the prefix. So, a preference named foo with a prefix of myExtension will be stored as myExtension.foo in the preferences files.

prefix

        return PreferencesImpl.manager.getPrefixedSystem(prefix);
    }

    // Constants for preference lookup contexts.
Public API

getUserPrefFile

Get the full path to the user-level preferences file.

Returns:
string
Path to the preferences file
    function getUserPrefFile() {

getViewState

Convenience function that gets a view state

id

context
nullable
Object
Optional additional information about the request

Public API

setViewState

Convenience function that sets a view state and then saves the file

id
string
preference to set
value
*
new value for the preference
context
nullable
Object
Optional additional information about the request
doNotSave
optional
boolean
