Example 60 with AionTransaction

use of org.aion.base.AionTransaction in project aion by aionnetwork.

the class AvmTransactionExecutor method executeTransactions.

/**
 * Executes the specified transactions using the avm, and returns the execution summaries of
 * each of the transactions.
 *
 * This method does not perform any checks on its inputs! It operates under the assumption that
 * the caller has ensured the input parameters are correct!
 *
 * In particular, every object supplied must be non-null with the exception of
 * {@code postExecutionWork}, which may be null. Also, we must have
 * {@code initialBlockEnergyLimit <= blockEnergyLimit}.
 *
 * @param repository The current state of the world.
 * @param blockDifficulty The block difficulty.
 * @param blockNumber The current block number.
 * @param blockTimestamp The block timestamp.
 * @param blockEnergyLimit The energy limit of the block.
 * @param miner The miner address.
 * @param transactions The transactions to execute.
 * @param postExecutionWork The post-execution work to be applied after executing the transactions.
 * @param decrementBlockEnergyLimit Whether or not to check the block energy limit.
 * @param allowNonceIncrement Whether to increment the sender's nonce or not.
 * @param isLocalCall Whether this is a local call (ie. is to cause no state changes).
 * @param remainingBlockEnergy The amount of energy remaining in the block.
 * @param executionType The avm execution type.
 * @param cachedBlockNumber The cached block number.
 * @param unityForkEnabled the flag shows the unityfork feature enabled/disabled
 * @param signatureSchemeSwapEnabled the flag shows the signatureSchemeSwap feature enabled/disabled
 * @return the execution summaries of the transactions.
 * @throws VmFatalException If a fatal error occurred and the kernel must be shut down.
