Functions

constructor

constructor() public

setValue

Update the oracle price for productId.

function setValue(ProductId productId, FPUnsigned value, uint64 timestamp) external

Parameters

Name	Type	Description
`productId`	ProductId	Product to update
`value`	FPUnsigned	New price for product
`timestamp`	uint64	Timestamp at which this price was generated. Must increase

setValues

Set oracle price for multiple products. See setValue()

function setValues(ProductId[] productIds, FPUnsigned[] values, uint64[] timestamps) external

Dev note

Reverts if any timestamp is <= previous timestamp

notifyPriceFeed

Notify PriceFeed, if registered, of all price updates

function notifyPriceFeed(ProductId productId, FPUnsigned value, uint64 timestamp) internal

Dev note

No-op if unregistered, so oracles can set up before PriceFeed or be used for other things

Parameters

Name	Type	Description
`productId`	ProductId	product being updated
`value`	FPUnsigned	new value
`timestamp`	uint64	time new value was generated

getValue

Get latest price for productId. Reverts if unavailable
