_sendPayoutsOf

Sends payouts to a project's current payout split group, according to its ruleset, up to its current payout limit.

If the percentages of the splits in the project's payout split group do not add up to 100%, the remainder is sent to the project's owner.

Anyone can send payouts on a project's behalf. Projects can include a wildcard split (a split with no hook, projectId, or beneficiary) to send funds to the _msgSender() which calls this function. This can be used to incentivize calling this function.

Payouts sent to addresses which aren't feeless incur the protocol fee.

function _sendPayoutsOf(
    uint256 projectId,
    address token,
    uint256 amount,
    uint256 currency
)
    internal
    returns (uint256 amountPaidOut);

Parameters

Name	Type	Description
projectId	uint256	The ID of the project to send the payouts of.
token	address	The token being paid out.
amount	uint256	The number of terminal tokens to pay out, as a fixed point number with same number of decimals as this terminal.
currency	uint256	The expected currency of the amount being paid out. Must match the currency of one of the project's current ruleset's payout limits.

Returns

Name	Type	Description
amountPaidOut	uint256	The total amount that was paid out.

_sendPayoutToSplit

Sends a payout to a split.

function _sendPayoutToSplit(
    JBSplit memory split,
    uint256 projectId,
    address token,

)
    internal
    returns (uint256, uint256 amountEligibleForFees);

Parameters
