Examples of SecondaryCursor

com.sleepycat.db.SecondaryCursor
A database cursor for a secondary database. Cursors are not thread safe and the application is responsible for coordinating any multithreaded access to a single cursor object.
Secondary cursors are returned by {@link SecondaryDatabase#openCursor SecondaryDatabase.openCursor} and{@link SecondaryDatabase#openSecondaryCursor SecondaryDatabase.openSecondaryCursor}. The distinguishing characteristics of a secondary cursor are:
- Direct calls to put() methods on a secondary cursor are prohibited.
- The {@link #delete} method of a secondary cursor will delete the primaryrecord and as well as all its associated secondary records.
- Calls to all get methods will return the data from the associated primary database.
- Additional get method signatures are provided to return the primary key in an additional pKey parameter.
- Calls to {@link #dup} will return a {@link SecondaryCursor}.
- The {@link #dupSecondary} method is provided to return a {@link SecondaryCursor} that doesn't require casting.
To obtain a secondary cursor with default attributes:
```
 SecondaryCursor cursor = myDb.openSecondaryCursor(txn, null); 
```
To customize the attributes of a cursor, use a CursorConfig object.
```
 CursorConfig config = new CursorConfig(); config.setDirtyRead(true); SecondaryCursor cursor = myDb.openSecondaryCursor(txn, config); 
```
