abstract class AbstractCashSelection
Pluggable interface to allow for different cash selection provider implementations
Default implementation in finance workflow module uses H2 database and a custom function within H2 to perform aggregation.
Custom implementations must implement this interface and declare their implementation in
META-INF/services/net.corda.finance.workflows.asset.selection.AbstractCashSelection

executeQuery |
A vendor specific query(ies) to gather Cash states that are available. abstract fun executeQuery(connection: Connection, amount: Amount<Currency>, lockId: UUID, notary: Party?, onlyFromIssuerParties: Set<AbstractParty>, withIssuerRefs: Set<OpaqueBytes>, withResultSet: (ResultSet) -> Boolean): Boolean |
isCompatible |
Upon dynamically loading configured Cash Selection algorithms declared in META-INF/services this method determines whether the loaded implementation is compatible and usable with the currently loaded JDBC driver. Note: the first loaded implementation to pass this check will be used at run-time. abstract fun isCompatible(metadata: DatabaseMetaData): Boolean |
toString |
abstract fun toString(): String |
unconsumedCashStatesForSpending |
Query to gather Cash states that are available and retry if they are temporarily unavailable. fun unconsumedCashStatesForSpending(services: ServiceHub, amount: Amount<Currency>, onlyFromIssuerParties: Set<AbstractParty> = emptySet(), notary: Party? = null, lockId: UUID, withIssuerRefs: Set<OpaqueBytes> = emptySet()): List<StateAndRef<State>> |
