Method Detail

getColumnDefinitions

public ColumnDefinitions getColumnDefinitions()

The columns returned in this ResultSet.

Returns:

the columns returned in this ResultSet.

isExhausted

public boolean isExhausted()

Test whether this ResultSet has more results.

Returns:

whether this ResultSet has more results.

one

public Row one()

Returns the the next result from this ResultSet.

Returns:

the next row in this resultSet or null if this ResultSet is exhausted.

all

public List<Row> all()

Returns all the remaining rows in this ResultSet as a list.

Returns:

a list containing the remaining results of this ResultSet. The returned list is empty if and only the ResultSet is exhausted.

iterator

public Iterator<Row> iterator()

An iterator over the rows contained in this ResultSet. The Iterator.next() method is equivalent to calling one(). So this iterator will consume results from this ResultSet and after a full iteration, the ResultSet will be empty. The returned iterator does not support the Iterator.remove() method.

Specified by:

iterator in interface Iterable<Row>

Returns:

an iterator that will consume and return the remaining rows of this ResultSet.

getQueryTrace

public QueryTrace getQueryTrace()

The query trace if tracing was enabled on this query.

Returns:

the QueryTrace object for this query if tracing was enable for this query, or null otherwise.

toString

public String toString()

Overrides:

toString in class Object
