getSerializedSize()
public int getSerializedSize ()
Get the number of bytes required to encode this message. The result is only computed on the
first call and memoized after that.
If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will
be smaller than the actual number of bytes required and might be negative.
