Method Detail

closeback to summary
public void close()

Implements org.jooq.Cursor.close.

Doc from org.jooq.Cursor.close.

Explicitly close the underlying PreparedStatement and ResultSet.

If you fetch all records from the underlying ResultSet, jOOQ Cursor implementations will close themselves for you. Calling close() again will have no effect.

fetchNextback to summary
public final Result<R> fetchNext(int number)

Implements org.jooq.Cursor.fetchNext.

Doc from org.jooq.Cursor.fetchNext.

Fetch the next couple of records from the cursor.

This will conveniently close the Cursor, after the last Record was fetched.

The result and its contained records are attached to the original Configuration by default. Use Settings#isAttachRecords() to override this behaviour.

Parameters
number:int

The number of records to fetch. If this is 0 or negative an empty list is returned, the cursor is untouched. If this is greater than the number of remaining records, then all remaining records are returned.

public boolean isClosed()

Implements org.jooq.Cursor.isClosed.

Doc from org.jooq.Cursor.isClosed.

Check whether this Cursor has been explicitly or "conveniently" closed.

Explicit closing can be achieved by calling close() from client code. "Convenient" closing is done by any of the other methods, when the last record was fetched.

public final Iterator<R> iterator()

Implements java.lang.Iterable.iterator.

Doc from java.lang.Iterable.iterator.

Returns an iterator over elements of type T.

Returns:Iterator<R>

an Iterator.

Annotations
@Override
resultSetback to summary
public final ResultSet resultSet()

Implements org.jooq.Cursor.resultSet.

Doc from org.jooq.Cursor.resultSet.

Get the Cursor's underlying ResultSet.

This will return a ResultSet wrapping the JDBC driver's ResultSet. Closing this ResultSet may close the producing Statement or PreparedStatement, depending on your setting for ResultQuery#keepStatement(boolean).

Modifying this ResultSet will affect this Cursor.

Returns:ResultSet

The underlying ResultSet. May be null, for instance when the Cursor is closed.
