public @interface RuleDependency
Declares a dependency upon a grammar rule, along with a set of zero or more
dependent rules.
Version numbers within a grammar should be assigned on a monotonically
increasing basis to allow for accurate tracking of dependent rules.

public abstract Dependents[] dependents
Specifies the set of grammar rules related to rule() which the
annotated element depends on. Even when absent from this set, the
annotated element is implicitly dependent upon the explicitly specified
rule(), which corresponds to the Dependents.SELF element.
By default, the annotated element is dependent upon the specified
rule() and its Dependents.PARENTS, i.e. the rule within
one level of context information. The parents are included since the most
frequent assumption about a rule is where it's used in the grammar.
- Default:
- {org.antlr.v4.runtime.Dependents.SELF, org.antlr.v4.runtime.Dependents.PARENTS}
