# RelayRegistrar
The RelayRegistrar Implementation
Keeps a list of registered relayers.
Provides view functions to read the list of registered relayers and filters out invalid ones.
Protects the list from spamming entries: only staked relayers are added.
# Functions
# constructor(uint256 _relayRegistrationMaxAge)
(public)
# getCreationBlock()
→ uint256 (external)
# Return values
block number in which the contract has been deployed.
# getRelayRegistrationMaxAge()
→ uint256 (external)
# Return values
maximum age the relay is considered registered by default by this RelayRegistrar, in seconds.
# setRelayRegistrationMaxAge(uint256 _relayRegistrationMaxAge)
(public)
Change the maximum relay registration age.
# supportsInterface(bytes4 interfaceId)
→ bool (public)
Returns true if this contract implements the interface defined by
interfaceId. See the corresponding
https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section]
to learn more about how these ids are created.
This function call must use less than 30 000 gas.
# registerRelayServer(address relayHub, bytes32[3] url)
(external)
This function is called by Relay Servers in order to register or to update their registration.
relayHub: The address of the RelayHub contract for which this action is performed.
url: The URL of the Relay Server that is listening to the clients' requests.
# addItem(address relayHub, address relayManager)
→ struct IRelayRegistrar.RelayInfo (internal)
# storeRelayServerRegistration(address relayManager, address relayHub, bytes32[3] url)
(internal)
# getRelayInfo(address relayHub, address relayManager)
→ struct IRelayRegistrar.RelayInfo (public)
relayManager: An address of a Relay Manager.
relayHub: The address of the RelayHub contract for which this action is performed.
# Return values
All the details of the given Relay Manager's registration. Throws if relay not found for RelayHub.
# readRelayInfos(address relayHub)
→ struct IRelayRegistrar.RelayInfo[] info (public)
Read relay info of registered Relay Server from an on-chain storage.
relayHub: The address of the RelayHub contract for which this action is performed.
# Return values
The list of RelayInfos of registered Relay Servers
# readRelayInfosInRange(address relayHub, uint256 oldestBlockNumber, uint256 oldestBlockTimestamp, uint256 maxCount)
→ struct IRelayRegistrar.RelayInfo[] info (public)
Read relay info of registered Relay Server from an on-chain storage.
relayHub: The address of the RelayHub contract for which this action is performed.
maxCount: The maximum amount of relays to be returned by this function.
oldestBlockNumber: The latest block number in which a Relay Server may be registered.
oldestBlockTimestamp: The latest block timestamp in which a Relay Server may be registered.
# Return values
The list of RelayInfos of registered Relay Servers
