Specified by:

isReadOnly in interface Query

Returns:

true, entities and proxies loaded by the query will be put in read-only mode false, entities and proxies loaded by the query will be put in modifiable mode

See Also:

Query.setReadOnly(boolean), The read-only/modifiable setting has no impact on entities/proxies returned by the query that existed in the session before the query was executed.

setReadOnly

public Query setReadOnly(boolean readOnly)

Set the read-only/modifiable mode for entities and proxies loaded by this Query. This setting overrides the default setting for the persistence context.

Specified by:

setReadOnly in interface Query

Parameters:

readOnly - true, entities and proxies loaded by the query will be put in read-only mode false, entities and proxies loaded by the query will be put in modifiable mode

See Also:

To set the default read-only/modifiable setting used for entities and proxies that are loaded into the session:, PersistenceContext.setDefaultReadOnly(boolean), Read-only entities are not dirty-checked and snapshots of persistent state are not maintained. Read-only entities can be modified, but changes are not persisted. When a proxy is initialized, the loaded entity will have the same read-only/modifiable setting as the uninitialized proxy has, regardless of the session's current setting. The read-only/modifiable setting has no impact on entities/proxies returned by the query that existed in the session before the query was executed.

Returns an array representing all named parameter names encountered during (intial) parsing of the query.

Note initial here means different things depending on whether this is a native-sql query or an HQL/filter query. For native-sql, a precursory inspection of the query string is performed specifically to locate defined parameters. For HQL/filter queries, this is the information returned from the query-translator. This distinction holds true for all parameter metadata exposed here.

Specified by:
