MACROMEDIA FLASH 8-FLASH LITE 2.X ACTIONSCRIPT LANGUAGE - Call (Function.call Method)

Function 369

call (Function.call method)
public call(thisObject:Object, [parameter1:Object])
Invokes the function represented by a Function object. Every function in ActionScript is
represented by a Function object, so all functions support this method.
In almost all cases, the function call (
()) operator can be used instead of this method. The
function call operator produces code that is concise and readable. This method is primarily
useful when the
thisObject parameter of the function invocation needs to be explicitly
controlled. Normally, if a function is invoked as a method of an object, within the body of the
function,
thisObject is set to myObject, as shown in the following example:
myObject.myMethod(1, 2, 3);
In some situations, you might want thisObject to point somewhere else; for example, if a
function must be invoked as a method of an object, but is not actually stored as a method of
that object:
myObject.myMethod.call(myOtherObject, 1, 2, 3);
You can pass the value null for the thisObject parameter to invoke a function as a regular
function and not as a method of an object. For example, the following function invocations
are equivalent:
Math.sin(Math.PI / 4)
Math.sin.call(null, Math.PI / 4)
Returns the value that the called function specifies as the return value.

Parameters
thisObject:Object - An object that specifies the value of thisObject within the function
body.

specify zero or more parameters.
