Function

The Function type is used to represent functions, function expressions, closures and class methods.

It contains a reference to the code to execute, the execution scope and possibly a bound "this" reference.

Properties

Qualifiers	Property	Type	Description
get	bound	Object	The bound object representing the "this" object for the function. Will be set to null if no object is bound. Use bind() to set the bound "this" object.
get	length	Number	null
get	name	String	The name of the function. Function expressions do not have a name and set the name property to the empty string.

(No own class methods defined)

Qualifiers	Method

Qualifiers	Method
	Function(args: Array)
	Create a function from the supplied formal parameter names and function body expression.
	apply(thisObject: Object, args: Array): Object
	Invoke the function on another object.
	bind(thisObj: Object, args: Array): Function
	Bind the value of "this" for the function.
	call(thisObject: Object, args: Array): Object
	Invoke the function on another object.

Function(args: Array)

Description: Create a function from the supplied formal parameter names and function body expression.

Parameters

args: Array

The parameters and body are suplied as discrete parameters to Function(), i.e. not as an array of args. Function ([args, ...], body).

apply(thisObject: Object, args: Array): Object

Parameters

thisObject: Object	The object to set as the "this" object when the function is called.
args: Array	Array of actual parameters to the function.

bind(thisObj: Object, args: Array): Function

Description: Bind the value of "this" for the function. This can set the value of "this" for the function. Use bound to examine the bound "this" value.

Parameters

thisObj: Object	Value of "this" to define.
args: Array	Function arguments to supply to the function. These arguments preceed any caller supplied arguments when the function is actually invoked.

call(thisObject: Object, args: Array): Object

Description: Invoke the function on another object. This function takes the "this" parameter and then a variable number of actual parameters to pass to the function.

Parameters

thisObject: Object	The object to set as the "this" object when the function is called.
args: Array	Actual parameters to the function.
