excessConfirmations

  uint8 public excessConfirmations;

Minimal required confirmations in case of too many confirmations

requiredOraclesCount

  uint8 public requiredOraclesCount;

Count of required oracles

oracleAddresses

  address[] public oracleAddresses;

Oracle addresses

getOracleInfo

  mapping(address => struct IOraclesManager.OracleInfo) public getOracleInfo;

Maps an oracle address to the oracle details

Functions

initialize

  function initialize(
            uint8 _minConfirmations,
            uint8 _excessConfirmations
  ) internal

Constructor that initializes the most important configurations.

Parameters:

Name	Type	Description
