This project has moved to be part of wpilibsuite/desktop-common
An alternative to JavaFX behavior classes that were placed in an internal module
in Java 9 with no publicly accessible replacement. This is not a one-to-one
replacement; the bindings API is more robust and functionally-focused;
actions are specified by lambda expressions or method references instead of
magic strings which API consumers must provide and switch on.
- No magic strings!
- Typos are compile-time exceptions, not runtime headaches
- Easier to define multiple inputs for single actions
- e.g. define multiple sets of key presses that result in the same action
- Builder pattern for creating bindings instead of weird with-ers (
.alt(),.shift(), etc)
