--------------------------
Summary: Optimize code of iot Server
Key: IOTDB-891
URL: https://issues.apache.org/jira/browse/IOTDB-891
Project: Apache IoTDB
Issue Type: Bug
Reporter: yuqi
Some logic can be simplify and refine like
{code:java}
@Override
public String getDevice() {
if (device != null) {
return device;
} else {
if (nodes.length == 1) {
return "";
}
StringBuilder s = new StringBuilder(nodes[0]);
for (int i = 1; i < nodes.length - 1; i++) {
s.append(TsFileConstant.PATH_SEPARATOR);
s.append(nodes[i]);
}
device = s.toString();
return device;
}
}
{code}
It's rather tedious
