Transaction simulation service interface

  • Method Details

    • simulatePendingBlockHeader

      ProcessableBlockHeader simulatePendingBlockHeader()
      Return a simulation of what could be current pending block, it can also be passed to simulate(Transaction, Optional, ProcessableBlockHeader, OperationTracer, boolean, boolean)
      Returns:
      the simulated pending block header

    • simulate

      @Deprecated(forRemoval=true) default Optional<TransactionSimulationResult> simulate(org.hyperledger.besu.datatypes.Transaction transaction, Optional<org.hyperledger.besu.datatypes.StateOverrideMap> stateOverrides, org.hyperledger.besu.datatypes.Hash blockHash, org.hyperledger.besu.evm.tracing.OperationTracer operationTracer, boolean isAllowExceedingBalance)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Simulate transaction execution at the block identified by the hash, with optional state overrides that can be applied before the simulation.
      Parameters:
      transaction - tx
      stateOverrides - state overrides to apply to this simulation
      blockHash - hash of the block
      operationTracer - the tracer
      isAllowExceedingBalance - should ignore the sender balance during the simulation?
      Returns:
      the result of the simulation
