Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`check(NodeTraversal t, Node n)`	Perform conformance check
`default @Nullable CheckConformance.Precondition`	`getPrecondition()`	Return a precondition for this rule.

- Method Detail
  - getPrecondition
```
default @Nullable CheckConformance.Precondition getPrecondition()
```
    Return a precondition for this rule.
    This method will only be called once (per rule) during the creation of the CheckConformance pass. Therefore, the return must be constant.
    Returning null means that there is no precondition. This is convenient, but can be a major performance hit.
  - check
```
void check(NodeTraversal t,
           Node n)
```
    Perform conformance check
