  - ### Method Detail

    - #### toIsolationLevel

          public static int toIsolationLevel(java.lang.String isolationLevelName)

      Maps a transaction isolation level name to the JDBC transaction isolation level.

      Accepted string names are `"TRANSACTION_NONE"`, `"TRANSACTION_READ_UNCOMMITTED"`, `"TRANSACTION_READ_COMMITTED"`, `"TRANSACTION_REPEATABLE_READ"`, `"TRANSACTION_SERIALIZABLE"`. To simplify mapping connection properties, the string value of the isolation level integer (e.g. `"2"` for `Connection.TRANSACTION_READ_COMMITTED`) is also accepted.

      Parameters:
        `isolationLevelName` - Transaction isolation level name or integer string (not `null`)
      Returns:
        JDBC standard isolation level value
      Throws:
        `java.lang.IllegalArgumentException` - For an unknown transaction isolation level name

    - #### toIsolationLevelName

          public static java.lang.String toIsolationLevelName(int isolationLevel)

      Maps a JDBC transaction isolation level to a string name.
      Parameters:
        `isolationLevel` - JDBC isolation level
      Returns:
        name of the isolation level (e.g. `"TRANSACTION_READ_COMMITTED"`)
      Throws:
        `java.lang.IllegalArgumentException` - When `isolationLevel` is not a known JDBC transaction isolation level

    - #### toIsolationLevelName

          public static java.lang.String toIsolationLevelName(int isolationLevel,
                                                              boolean lenient)

      Maps a JDBC transaction isolation level to a string name.
      Parameters:
        `isolationLevel` - JDBC isolation level
        `lenient` - `true` return integer string for unknown values, `false` throw `IllegalArgumentException` for unknown values
      Returns:
        name of the isolation level (e.g. TRANSACTION_READ_COMMITTED), or, when `lenient` is `true`, the integer string for unknown values
      Throws:
        `java.lang.IllegalArgumentException` - When `isolationLevel` is not a known JDBC transaction isolation level and `lenient` is `false`
