@DoNotImplement abstract class BaseTransaction : NamedByHash
An abstract class defining fields shared by all transaction types in the system.
<init> |
An abstract class defining fields shared by all transaction types in the system. BaseTransaction() |
inputs |
The inputs of this transaction. Note that in BaseTransaction subclasses the type of this list may change! abstract val inputs: List<*> |
notary |
If present, the notary for this transaction. If absent then the transaction is not notarised at all. This is intended for issuance/genesis transactions that don't consume any other states and thus can't double spend anything. abstract val notary: Party? |
outputs |
Ordered list of states defined by this transaction, along with the associated notaries. abstract val outputs: List<TransactionState<ContractState>> |
outputStates |
Helper property to return a list of ContractState objects, rather than the often less convenient TransactionState val outputStates: List<ContractState> |
references |
A list of reusable reference data states which can be referred to by other contracts in this transaction. abstract val references: List<*> |
checkBaseInvariants |
open fun checkBaseInvariants(): Unit |
filterOutputs |
Helper to simplify filtering outputs according to a Predicate. fun <T : ContractState> filterOutputs(clazz: Class<T>, predicate: Predicate<T>): List<T>fun <T : ContractState> filterOutputs(predicate: (T) -> Boolean): List<T> |
filterOutRefs |
Helper to simplify filtering output StateAndRef items according to a Predicate. fun <T : ContractState> filterOutRefs(clazz: Class<T>, predicate: Predicate<T>): List<StateAndRef<T>>fun <T : ContractState> filterOutRefs(predicate: (T) -> Boolean): List<StateAndRef<T>> |
findOutput |
Helper to simplify finding a single output matching a Predicate. fun <T : ContractState> findOutput(clazz: Class<T>, predicate: Predicate<T>): Tfun <T : ContractState> findOutput(predicate: (T) -> Boolean): T |
findOutRef |
Helper to simplify finding a single output StateAndRef matching a Predicate. fun <T : ContractState> findOutRef(clazz: Class<T>, predicate: Predicate<T>): StateAndRef<T>fun <T : ContractState> findOutRef(predicate: (T) -> Boolean): StateAndRef<T> |
getOutput |
Helper to simplify getting an indexed output. fun getOutput(index: Int): ContractState |
outputsOfType |
Helper to simplify getting all output states of a particular class, interface, or base class. fun <T : ContractState> outputsOfType(clazz: Class<T>): List<T>fun <T : ContractState> outputsOfType(): List<T> |
outRef |
Returns a StateAndRef for the given output index. fun <T : ContractState> outRef(index: Int): StateAndRef<T>
Returns a StateAndRef for the requested output state, or throws IllegalArgumentException if not found. fun <T : ContractState> outRef(state: ContractState): StateAndRef<T> |
outRefsOfType |
Helper to simplify getting all output StateAndRef items of a particular state class, interface, or base class. fun <T : ContractState> outRefsOfType(clazz: Class<T>): List<StateAndRef<T>>fun <T : ContractState> outRefsOfType(): List<StateAndRef<T>> |
toString |
open fun toString(): String |
CoreTransaction |
A transaction with the minimal amount of information required to compute the unique transaction id, and resolve a FullTransaction. This type of transaction, wrapped in SignedTransaction, gets transferred across the wire and recorded to storage. abstract class CoreTransaction : BaseTransaction |
FullTransaction |
A transaction with fully resolved components, such as input states. abstract class FullTransaction : BaseTransaction |
