Annotation Interface Expression

@Target(METHOD) @Retention(CLASS) @Repeatable(Expressions.class) public @interface Expression
Allows you to use java-like strings to target complex pieces of bytecode.

Your injector annotation should use @At("MIXINEXTRAS:EXPRESSION"), and your handler method should have an @Expression annotation attached.

See the wiki article for more info.
