Examples with Transaction io.nuls.kernel.model.Transaction used on opensource projects

Example 31 with Transaction

use of io.nuls.kernel.model.Transaction in project nuls by nuls-io.

the class NulsProtocolProcess method clearIncompatibleTx.

public void clearIncompatibleTx() {
    TransactionQueueStorageService tqs = NulsContext.getServiceBean(TransactionQueueStorageService.class);
    while (tqs.pollTx() != null) {
    }
    TransactionCacheStorageService tcs = NulsContext.getServiceBean(TransactionCacheStorageService.class);

    while ((tx = tcs.pollTx()) != null) {
        tcs.removeTx(tx.getHash());
    }
    TxMemoryPool.getInstance().clear();
}

Example 32 with Transaction

use of io.nuls.kernel.model.Transaction in project nuls by nuls-io.

the class TransactionServiceImpl method conflictDetect.

/**
 * 冲突检测，检测如果传入的交易列表中有相冲突的交易，则返回失败，写明失败原因及所有的应该舍弃的交易列表
 * <p>
 * Conflict detection, which detects conflicting transactions in the incoming transaction list, returns failure,
 * indicating the cause of failure and all the list of trades that should be discarded.
 *
 * @param txList 需要检查的交易列表/A list of transactions to be checked.
 * @return 操作结果：成功则返回successResult，失败时，data中返回丢弃列表，msg中返回冲突原因
 * Operation result: success returns successResult. When failure, data returns the discard list, and MSG returns the cause of conflict.
