DefaultQueryMetadata (Querydsl 4.1.3 API)

java.lang.Object
- com.querydsl.core.DefaultQueryMetadata

All Implemented Interfaces:

QueryMetadata, Serializable, Cloneable

Direct Known Subclasses:

OrderedQueryMetadata
```
public class DefaultQueryMetadata
extends Object
implements QueryMetadata, Cloneable
```
DefaultQueryMetadata is the default implementation of the QueryMetadata interface.
DefaultQueryMetadata is mutable, but clone() can be used to created deep copies to refine the state without modifying the initial instance.
