StaticPointer

class StaticPointer<T : ContractState>(val pointer: StateRef, val type: Class<T>, val isResolved: Boolean = false) : StatePointer<T>

A StaticPointer contains a pointer to a specific StateRef and can be resolved by looking up the StateRef via ServiceHub. There are a number of things to keep in mind when using StaticPointers:

The ContractState being pointed to may be spent or unspent when the pointer is resolved
The ContractState may not be known by the node performing the look-up in which case the resolve method will throw a TransactionResolutionException

Constructors

StaticPointer

constructor(pointer: StateRef, type: Class<T>)

Allows this class to be evolved through backwards compatibility with version 1 of this class.

constructor(pointer: StateRef, type: Class<T>, isResolved: Boolean = false)

Properties

isResolved

open override val isResolved: Boolean = false

Determines whether the state pointer should be resolved to a reference input when used in a transaction.

pointer

open override val pointer: StateRef

An identifier for the ContractState that this StatePointer points to.

type

open override val type: Class<T>

Type of the state which is being pointed to.

Functions

equals

open operator override fun equals(other: Any?): Boolean

hashCode

open override fun hashCode(): Int

resolve

open override fun resolve(services: ServiceHub): StateAndRef<T>

Resolves a StaticPointer to a StateAndRef via a StateRef look-up.

open override fun resolve(ltx: LedgerTransaction): StateAndRef<T>

Resolves a StatePointer to a StateAndRef from inside a LedgerTransaction. The intuition here is that all of the pointed-to states will be included in the transaction as reference states.
