Hi,
I would like to cache query objects in a hash map. My implementation
failed, because not all of the Query classes are implementing the
necessary method: "public int hashCode()". The same counts for the
"public boolean equals (Object o)", "public String toString(String
fieldName)" and "public String toString()". To force all subclasses of
Query to implement this 4 methods, i would like to make them abstract
within the base class and implement the missing ones in the subclasses.
So in Query class itself, it would look:
public abstract String toString(String field);
public abstract String toString();
public abstract int hashCode();
public abstract boolean equals(Object o);
I think this would make the API cleaner and more usable.
Thoughts ???
