createString
public String createString()
- Description copied from class:
AbstractCQFilter
- Creates a string representation of the continuous query filter, this method is
used by AbstractCQFilter.toString().
The string will be used for identifying and comparing filters,
i.e. it will be used in AbstractCQFilter.hashCode() and AbstractCQFilter.equals(Object),
so the returned value must be in unique format among all filters
in the system.
- Specified by:
createString
in class AbstractCQFilter<Object,Object,Object,String>
- Returns:
- " matches
