Mismatched query and update of collection
Reports collections whose contents are either queried and not updated, or updated and not queried.
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
MismatchedQueryAndUpdateOfCollection
Such inconsistent queries and updates are pointless and may indicate either dead code or a typo.
Use the inspection settings to specify name patterns that correspond to update/query methods. Query methods that return an element are automatically detected, and only those that write data to an output parameter (for example, an OutputStream
) need to be specified.
Example:
Suppose you have your custom FixedStack
class with method store()
:
public class FixedStack<T> extends Collection<T> {
public T store(T t) {
// implementation
}
}
You can add store
to the update methods table in order to report mismatched queries like:
void test(int i) {
FixedStack<Integer> stack = new FixedStack<>();
stack.store(i);
}
Here you can find the description of settings available for the Mismatched query and update of collection inspection, and the reference of their default values.
