# DataVendingFlow

`open class DataVendingFlow : FlowLogic<Void?>`

### Constructors

#### <init> | `DataVendingFlow(otherSideSession: FlowSession, payload: Any)`

### Properties

#### otherSideSession | `val otherSideSession: FlowSession`
#### payload | `val payload: Any`

### Functions

#### call | This is where you fill out your business logic. `open fun call(): Void?`
#### sendPayloadAndReceiveDataRequest | `open fun sendPayloadAndReceiveDataRequest(otherSideSession: FlowSession, payload: Any): UntrustworthyData<Request>`
#### verifyDataRequest | `open fun verifyDataRequest(dataRequest: Data): Unit`

### Extension Functions

#### receiveAll | Suspends until a message has been received for each session in the specified sessions. `fun FlowLogic<*>.receiveAll(session: Pair<FlowSession, Class<out Any>>, vararg sessions: Pair<FlowSession, Class<out Any>>): Map<FlowSession, UntrustworthyData<Any>>` `fun <R : Any> FlowLogic<*>.receiveAll(receiveType: Class<R>, session: FlowSession, vararg sessions: FlowSession): List<UntrustworthyData<R>>` `fun <R : Any> FlowLogic<*>.receiveAll(session: FlowSession, vararg sessions: FlowSession): List<UntrustworthyData<R>>`

### Inheritors

#### SendStateAndRefFlow | The SendStateAndRefFlow should be used to send a list of input StateAndRef to another peer that wishes to verify the input's integrity by resolving and checking the dependencies as well. The other side should invoke ReceiveStateAndRefFlow at the right point in the conversation to receive the input state and ref and perform the resolution back-and-forth required to check the dependencies. `open class SendStateAndRefFlow : DataVendingFlow`
#### SendTransactionFlow | The SendTransactionFlow should be used to send a transaction to another peer that wishes to verify that transaction's integrity by resolving and checking the dependencies as well. The other side should invoke ReceiveTransactionFlow at the right point in the conversation to receive the sent transaction and perform the resolution back-and-forth required to check the dependencies and download any missing attachments. `open class SendTransactionFlow : DataVendingFlow`
