Class: baseclass

Methods

staticLuCI.baseclass.extend(properties){LuCI.baseclass}

luci.js, line 89

Extends this base class with the properties described in properties and returns a new subclassed Class instance

Name	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 sublassed 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}

luci.js, line 172

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.

staticLuCI.baseclass.isSubclass(classValue){boolean}

luci.js, line 198

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 given classValue is a subclass of this class or false if the given value is not a valid class or not a subclass of this class'.

staticLuCI.baseclass.singleton(properties, new_args){LuCI.baseclass}

luci.js, line 148

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 subsequent new.

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.

super(key, callArgs){*|null}

luci.js, line 270

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 optional callArgs array is given.

This function has two signatures and is sensitive to the amount of arguments passed to it:

• super('key') - Returns the value of key when found within one of the parent classes.
• super('key', ['arg1', 'arg2']) - Calls the key() method with parameters arg1 and arg2 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 when callArgs are specified and the found member named by key 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 returned null.

varargs(args, offset, extra_args){Array.<*>}

luci.js, line 228

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 resultung array.

Returns:

Type	Description
Array.<*>	Returns a new array consisting of the optional extra arguments and the values extracted from the args array beginning with offset.
