Examples of java.nio.BufferOverflowException

java.nio.BufferOverflowException
A BufferOverflowException is thrown when you try to write elements to a buffer, but there is not enough remaining space in the buffer.

        byte[] b, int offset){
      if(readIndex<minIndex){
        throw new BufferUnderflowException();
      }
      if(readIndex>=index){
        throw new BufferOverflowException();
      }
      int k=(int)(readIndex%bufferSize);
      readBuffer.position(k*streamMaxSize+readOffset);
      int l=lengths[k];
      if(readLength<0){
        l-=readOffset;
        readBuffer.get(b,offset,l);
      }
      else{
        if(l-readOffset<readLength){
          throw new BufferOverflowException();
        }
        l=readLength;
        readBuffer.get(b,offset,l);
      }
