_FindNewViolationsOfRule()

PRESUBMIT_test_mocks.MockCannedChecks._FindNewViolationsOfRule (   self,   callable_rule,   input_api,   source_file_filter = None,   error_formatter = _ReportErrorFileAndLine  )

protected

Find all newly introduced violations of a per-line rule (a callable).

Arguments:
  callable_rule: a callable taking a file extension and line of input and
    returning True if the rule is satisfied and False if there was a
    problem.
  input_api: object to enumerate the affected files.
  source_file_filter: a filter to be passed to the input api.
  error_formatter: a callable taking (filename, line_number, line) and
    returning a formatted error string.

Returns:
  A list of the newly-introduced violations reported by the rule.
