Interface for defining a custom Processor that can modify or validate GrooCSS input.
By extending this interface you can write your own custom validators and add them via Config.
You could also write your own Processor that modifies values in the PRE_VALIDATE phase or any other Phase. For example:
class ConvertAllIntsToPixels implements Processor< Style > {
Optional process(Style style, Phase phase) {
if (phase == Phase.PRE_VALIDATE && style.value instanceof Integer) {
style.value = new Measurement(style.value, 'px')
}
return Optional.empty();
}
