#google_re2 ⇒ Google::Apis::TrafficdirectorV3::GoogleRe2

Google's RE2_ regex engine. The regex string must adhere to the documented syntax_. The engine is designed to complete execution in linear time as well as limit the amount of memory used. Envoy supports program size checking via runtime. The runtime keys re2.max_program_size.error_level and re2. max_program_size.warn_level can be set to integers as the maximum program size or complexity that a compiled regex can have before an exception is thrown or a warning is logged, respectively. re2.max_program_size. error_level defaults to 100, and re2.max_program_size.warn_level has no default if unset (will not check/log a warning). Envoy emits two stats for tracking the program size of regexes: the histogram re2.program_size, which records the program size, and the counter re2.exceeded_warn_level, which is incremented each time the program size exceeds the warn level threshold. Corresponds to the JSON property googleRe2

Returns:

• (Google::Apis::TrafficdirectorV3::GoogleRe2)

# File 'lib/google/apis/trafficdirector_v3/classes.rb', line 1258

def google_re2
  @google_re2
end

#regex ⇒ String

The regex match string. The string must be supported by the configured engine. The regex is matched against the full string, not as a partial match. Corresponds to the JSON property regex

Returns:

• (String)
