Revision: Add helper method for comparison to Revision.NULL When Error Prone checks are enabled, comparing to Revision.NULL with the == or != operator results in a warning: [ReferenceEquality] Comparison using reference equality instead of value equality The NULL instance is used as a sentinel, so comparing with reference equality is correct. Rather than suppressing the warning at every place in the code, add a helper method that can be used, and suppress the warning only there. Note that the "ReferenceEquality" warning is Error Prone specific and suppressing it results in an "Unsupported @SuppressWarnings" warning. Change-Id: Ia50404f76f88c405b9298a645760c019384c92ff
