示例1: readFields
import org.apache.hadoop.mapreduce.Counter; //導入方法依賴的package包/類
@Override
public void readFields(DataInput in) throws IOException {
clear();
int len = WritableUtils.readVInt(in);
T[] enums = enumClass.getEnumConstants();
for (int i = 0; i < len; ++i) {
int ord = WritableUtils.readVInt(in);
Counter counter = newCounter(enums[ord]);
counter.setValue(WritableUtils.readVLong(in));
counters[ord] = counter;
}
}
