const script& output_script, const output_point& outpoint)
{
payment_address address;
if (!extract(address, output_script))

continue;
// We found the address entry we were looking for.
BITCOIN_ASSERT(!is_found);
is_found = true;
// Put changes into batch finally.
batch.Delete(it->key());
break;
}
BITCOIN_ASSERT(it->status().ok());
if (!is_found)
return false;
return true;
}示例2: remove_credit
bool remove_credit(leveldb::WriteBatch& batch,
const transaction_output_type& output, const output_point& outpoint)
{
payment_address address;
// Not a Bitcoin address so skip this output.
if (!extract(address, output.script))
return true;
data_chunk addr_key = create_address_key(address, outpoint);
batch.Delete(slice(addr_key));
return true;
}示例3: seq_del
void c_seq::seq_del(uint32 keyId, leveldb::WriteBatch& bh)
{
bh.Delete(__tos(m_key << "@" << keyId));
m_seq_head.s_count(m_seq_head.g_count() - 1);
//LOG4_ERROR("SEQ DEL KEY:" << __tos(m_key << "@" << keyId));
