function registerPricer(
    uint256 id,
    address addr
) public returns (bool)

Register a new pricer to registry.

Only owner of registry can register a new pricer. Each id can only be assigned to one pricer, and assigned once, with no modification allowed.

parameters:

Name	Type	Description
id	uint256	Pricer id to assign
addr	address	Pricer contract address

getAmountOut

function getAmountOut(
    uint256 amountIn,
    uint256 fee,
    uint256 id,
    address treasury,
    address tokenIn,
    address tokenOut
) public view returns (uint amountOut)

Calculate amount of output token, given amount of input token, fee ratio, pricer id, treasury address, and input and output token address.

parameters:

Name	Type	Description
amountIn	uint256	Amount of input token
fee	uint256	Fee ratio, in basis point. e.g. 100 means 1% fee
id	unit256	Pricer whose logic would be applied for computation
treasury	address	Treasury address where to read asset balance from, as input of computation
tokenIn	address	Input token
tokenOut	address	Output token
