Fdef : Maybe : Ref : AbstractFunction : Object

lazy function proxy
Source: Fdef.sc

Description

Fdef is a placeholder for functions. Fdef allows dynamically replacing functions while they are being used.

See also: Maybe and the JITLib overview.

Class Methods

Fdef.new(key, val)

Arguments:

key

if no instance exists with this name, create a new one, otherwise return the existing one.

val

If a Function is given, replace the old function with the new one.

Inherited class methods

Undocumented class methods

Fdef.all

Fdef.all = value

Instance Methods

Inherited instance methods

Examples

Fdef(\x, { 8 + 9 });

Fdef(\y, Fdef(\x) - 3);

Fdef(\y).value;

Fdef(\x, 3);

Fdef(\y).value;

Fdef(\x, { |x=0| x });


Fdef(\x).value(8);

Fdef(\y).value(8);


z = Fdef(\x) * Fdef(\y) + { 1.0.rand };

z.value;
z.value(400);
