abstract class AbstractConserveAmount<S : FungibleAsset<T>, C : CommandData, T : Any> : Clause<S, C, Issued<T>>
Standardised clause for checking input/output balances of fungible assets. Requires that a Move command is provided, and errors if absent. Must be the last clause under a grouping clause; errors on no-match, ends on match.

requiredCommands |
open val requiredCommands: Set<Class<out CommandData>> Determine whether this clause runs or not |
generateExit |
fun generateExit(tx: TransactionBuilder, amountIssued: Amount<Issued<T>>, assetStates: List<StateAndRef<S>>, deriveState: (TransactionState<S>, Amount<Issued<T>>, PublicKey) -> TransactionState<S>, generateMoveCommand: () -> CommandData, generateExitCommand: (Amount<Issued<T>>) -> CommandData): PublicKey Generate an transaction exiting fungible assets from the ledger. |
generateSpend |
fun generateSpend(tx: TransactionBuilder, amount: Amount<T>, to: PublicKey, assetsStates: List<StateAndRef<S>>, onlyFromParties: Set<Party>? = null, deriveState: (TransactionState<S>, Amount<Issued<T>>, PublicKey) -> TransactionState<S>, generateMoveCommand: () -> CommandData): List<PublicKey> Generate a transaction that consumes one or more of the given input states to move assets to the given pubkey. Note that the vault is not updated: its up to you to do that. |
toString |
open fun toString(): String |
verify |
open fun verify(tx: TransactionForContract, inputs: List<S>, outputs: List<S>, commands: List<AuthenticatedObject<C>>, groupingKey: Issued<T>?): Set<C> Verify the transaction matches the conditions from this clause. For example, a "no zero amount output" clause would check each of the output states that it applies to, looking for a zero amount, and throw IllegalStateException if any matched. |
matches |
fun <C : CommandData> Clause<*, C, *>.matches(commands: List<AuthenticatedObject<C>>): Boolean Determine if the given list of commands matches the required commands for a clause to trigger. |
