Example 1 with FvmWrappedTransactionResult

use of org.aion.fastvm.FvmWrappedTransactionResult in project aion by aionnetwork.

the class FvmTransactionExecutor method executeTransactions.

/**
 * Executes the specified array of transactions using the FVM and returns a list of transaction
 * summaries, such that the i'th summary pertains to the i'th transaction in the input.
 *
 * <p>If no post-execution work is specified then none will be run. Otherwise, the
 * post-execution work will be applied in such a way that it appears, from the caller's
 * perspective, as if it was run immediately after each transaction sequentially.
 *
 * @param repository The current snapshot of the kernel's repository layer.
 * @param blockDifficulty The current best block's difficulty.
 * @param blockNumber The current best block number.
 * @param blockTimestamp The current best block timestamp.
 * @param blockNrgLimit The current best block energy limit.
 * @param blockCoinbase The address of the miner.
 * @param transactions The transactions to execute.
 * @param postExecutionWork The post-execute work, if any, to be run immediately after each
 *     transaction completes.
 * @param logger A logger.
 * @param decrementBlockEnergyLimit Whether to decrement the block energy limit (ie. if no
 *     decrement implication is block overflow won't be checked)
 * @param allowNonceIncrement Whether to increment the sender nonce.
 * @param isLocalCall Whether this is a local call or not.
 * @param fork040enabled Whether or not the 0.4.0 fork is enabled.
 * @param initialBlockEnergyLimit The initial block energy limit at the time of running these
 *     transactions.
 * @return a list of transaction summaries pertaining to the transactions.
