Module: Processing::Proxy
- Includes:
- Math
- Defined in:
- lib/ruby-processing/app.rb
Overview
This module will get automatically mixed in to any inner class of a Processing::App, in order to mimic Java’s inner classes, which have unfettered access to the methods defined in the surrounding class.
Class Method Summary collapse
-
.desired_method_names ⇒ Object
Generate the list of method names that we’d like to proxy for inner classes.
-
.included(inner_class) ⇒ Object
Don’t do all of the work unless we have an inner class that needs it.
-
.proxy_constants ⇒ Object
Proxy the sketch’s constants on to the inner classes.
-
.proxy_methods ⇒ Object
Proxy methods through to the sketch.
Class Method Details
.desired_method_names ⇒ Object
Generate the list of method names that we’d like to proxy for inner classes. Nothing camelCased, nothing __internal__, just the Processing API.
