Class org.apache.hadoop.io.DataOutputBuffer

Examples of org.apache.hadoop.io.DataOutputBuffer.writeInt()

org.apache.hadoop.io.DataOutputBuffer.writeInt()
Overwrite an integer into the internal buffer. Note that this call can only be used to overwrite existing data in the buffer, i.e., buffer#count cannot be increased, and DataOutputStream#written cannot be increased.

          int dataLength = d.getLength();
          out.writeInt(dataLength);      //first put the data length
