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.

        dataPos += len;

      void  writeChecksum(byte[] inarray, int off, int len) {
        if (checksumPos + len > dataStart) {
          throw new BufferOverflowException();
        }
        System.arraycopy(inarray, off, buf, checksumPos, len);
        checksumPos += len;
      }
