Method Detail

isExhausted

boolean isExhausted()

See Also:

PagingIterable.isExhausted()

isFullyFetched

boolean isFullyFetched()

See Also:

PagingIterable.isFullyFetched()

getAvailableWithoutFetching

int getAvailableWithoutFetching()

See Also:

PagingIterable.getAvailableWithoutFetching()

fetchMoreResults

ResultSet fetchMoreResults(Handler<AsyncResult<Void>> handler)

Parameters:

handler - handler called when result is fetched

See Also:

PagingIterable.fetchMoreResults()

one

ResultSet one(Handler<AsyncResult<com.datastax.driver.core.Row>> handler)

The method should not be used concurrently with others like several(int, Handler) or all(Handler). This may lead to unexpected result.

Parameters:

handler - handler called when one row is fetched

See Also:

ResultSet.one()

several

ResultSet several(int amount,
                  Handler<AsyncResult<List<com.datastax.driver.core.Row>>> handler)

Fetch a specific amount of rows and notify via a handler.

If remaining amount of rows in a result set is less than desired amount of rows to fetch, the handler will be called with a successful result encompassing just the remaining rows.

The method should not be used concurrently with others like one(Handler) or all(Handler). This may lead to unexpected result.

Parameters:

handler - the handler

amount - the amount

all

ResultSet all(Handler<AsyncResult<List<com.datastax.driver.core.Row>>> handler)

The method should not be used concurrently with others like several(int, Handler) or one(Handler). This may lead to unexpected result.

Parameters:

handler - handler called when all the rows is fetched

See Also:

PagingIterable.all()

getColumnDefinitions

com.datastax.driver.core.ColumnDefinitions getColumnDefinitions()

See Also:

ResultSet.getColumnDefinitions()

wasApplied

boolean wasApplied()

See Also:

ResultSet.wasApplied()

getExecutionInfo

com.datastax.driver.core.ExecutionInfo getExecutionInfo()

See Also:

PagingIterable.getExecutionInfo()

getAllExecutionInfo

List<com.datastax.driver.core.ExecutionInfo> getAllExecutionInfo()

See Also:

PagingIterable.getExecutionInfo()
