FilterDef (Hibernate JavaDocs)

```
@Target({TYPE,PACKAGE})
@Retention(RUNTIME)
@Repeatable(FilterDefs.class)
public @interface FilterDef
```
Declares a filter, specifying its name(), optionally, a default condition, and its parameter names and types, if it has parameters.
Every entity or collection which is affected by a named filter declared using this annotation must be explicitly annotated @Filter, and the name of this filter definition must be given. The @Filter annotation may override the default condition specified by this annotation using Filter.condition().
For example, if a filter is declared as follows:
```
 {@code
```

String defaultCondition
```
    The default filter condition, a SQL expression used for filtering the rows returned by a query when the filter is enabled. This default condition may be overridden by any entity or collection to which the filter applies using Filter.condition().
    If every entity and collection to which the filter applies explicitly specifies its own filter condition, then the default condition is unnecessary, and so this member is optional.
