class FilterOn<S : ContractState, C : CommandData, K : Any> : Clause<ContractState, C, K>
Filter the states that are passed through to the wrapped clause, to restrict them to a specific type.
<init> |
FilterOn(clause: Clause<S, C, K>, filterStates: (List<ContractState>) -> List<S>) Filter the states that are passed through to the wrapped clause, to restrict them to a specific type. |
clause |
val clause: Clause<S, C, K> |
filterStates |
val filterStates: (List<ContractState>) -> List<S> |
requiredCommands |
val requiredCommands: Set<Class<out CommandData>> Determine whether this clause runs or not |
getExecutionPath |
fun getExecutionPath(commands: List<AuthenticatedObject<C>>): List<Clause<*, *, *>> Determine the subclauses which will be verified as a result of verifying this clause. |
verify |
fun verify(tx: TransactionForContract, inputs: List<ContractState>, outputs: List<ContractState>, commands: List<AuthenticatedObject<C>>, groupingKey: K?): 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. |
