Methods
-
staticLuCI.baseclass.extend(properties){LuCI.baseclass}
-
Extends this base class with the properties described in
properties
and returns a new subclassed Class instanceName Type Description properties
Object.<string, *> An object describing the properties to add to the new subclass.
Returns:
Type Description LuCI.baseclass Returns a new LuCI.baseclass subclassed from this class, extended by the given properties and with its prototype set to this base class to enable inheritance. The resulting value represents a class constructor and can be instantiated with new
. -
staticLuCI.baseclass.instantiate(params, new_args){LuCI.baseclass}
-
Calls the class constructor using
new
with the given argument array being passed as variadic parameters to the constructor.Name Type Description params
Array.<*> An array of arbitrary values which will be passed as arguments to the constructor function.
new_args
* optional repeatable Specifies arguments to be passed to the subclass constructor as-is in order to instantiate the new subclass.
Returns:
Type Description LuCI.baseclass Returns a new LuCI.baseclass instance extended by the given properties with its prototype set to this base class to enable inheritance. -
Checks whether the given class value is a subclass of this class.
Name Type Description classValue
LuCI.baseclass The class object to test.
Returns:
Type Description boolean Returns true
when the givenclassValue
is a subclass of this class orfalse
if the given value is not a valid class or not a subclass of this class'. -
staticLuCI.baseclass.singleton(properties, new_args){LuCI.baseclass}
-
Extends this base class with the properties described in
properties
, instantiates the resulting subclass using the additional optional arguments passed to this function and returns the resulting subclassed Class instance.This function serves as a convenience shortcut for
Class.extend()
and subsequentnew
.Name Type Description properties
Object.<string, *> An object describing the properties to add to the new subclass.
new_args
* optional repeatable Specifies arguments to be passed to the subclass constructor as-is in order to instantiate the new subclass.
Returns:
Type Description LuCI.baseclass Returns a new LuCI.baseclass instance extended by the given properties with its prototype set to this base class to enable inheritance. -
Walks up the parent class chain and looks for a class member called
key
in any of the parent classes this class inherits from. Returns the member value of the superclass or calls the member as function and returns its return value when the optionalcallArgs
array is given.This function has two signatures and is sensitive to the amount of arguments passed to it:
super('key')
- Returns the value ofkey
when found within one of the parent classes.super('key', ['arg1', 'arg2'])
- Calls thekey()
method with parametersarg1
andarg2
when found within one of the parent classes.
Name Type Description key
string The name of the superclass member to retrieve.
callArgs
Array.<*> optional An optional array of function call parameters to use. When this parameter is specified, the found member value is called as function using the values of this array as arguments.
Throws:
-
Throws a
ReferenceError
whencallArgs
are specified and the found member named bykey
is not a function value. - Type
- ReferenceError
Returns:
Type Description * | null Returns the value of the found member or the return value of the call to the found method. Returns null
when no member was found in the parent class chain or when the call to the superclass method returnednull
. -
Extract all values from the given argument array beginning from
offset
and prepend any further given optional parameters to the beginning of the resulting array copy.Name Type Description args
Array.<*> The array to extract the values from.
offset
number The offset from which to extract the values. An offset of
0
would copy all values till the end.extra_args
* optional repeatable Extra arguments to add to prepend to the resulting array.
Returns:
Type Description Array.<*> Returns a new array consisting of the optional extra arguments and the values extracted from the args
array beginning withoffset
.
