Name	Type	Description
[0]	string	The market id

setMarketId

function setMarketId(string newMarketId) external

Associates an id with a specific PoolAddressesProvider.

This can be used to create an onchain registry of PoolAddressesProviders to identify and validate multiple ParaSpace markets.

getAddress

function getAddress(bytes32 id) public view returns (address)

Returns an address by its identifier.

The returned address might be an EOA or a contract, potentially proxied It returns ZERO if there is no registered address with the given id

Name	Type	Description
[0]	address	The address of the registered for the specified id

setAddress

function setAddress(bytes32 id, address newAddress) external

Sets an address for an id replacing the address saved in the addresses map.

IMPORTANT Use this function carefully, as it will do a hard replacement

id	bytes32	The id
newAddress	address	The address to set

setAddressAsProxy

function setAddressAsProxy(bytes32 id, address newImplementationAddress) external

General function to update the implementation of a proxy registered with certain id. If there is no proxy registered, it will instantiate one and set as implementation the newImplementationAddress.

IMPORTANT Use this function carefully, only for ids that don't have an explicit setter function, in order to avoid unexpected consequences

_init	address	The address of the contract or implementation to execute _calldata
_calldata	bytes	A function call, including function selector and arguments _calldata is executed with delegatecall on _init

getPoolConfigurator

function getPoolConfigurator() external view returns (address)

Returns the address of the PoolConfigurator proxy.
