----------------------------------------------------------------------
{quote} As long as BytesType is declared as the type of argument, the type
system ensure it will only be called on that{quote}
This is what is expected, but as per the code in BytesType.java in cassandra
2.1 branch on git as given below:
{code}
public boolean isValueCompatibleWithInternal(AbstractType<?> otherType)
{
// BytesType can read anything
return true;
}
{code}
true is returned for every standard type (like text,int etc) and the sizeof
calculates size for them,which is contradictory to how we want the sizeof() to
behave. That is why I had introduced the type check in Selection.
