Interface ReactiveRow

All Superinterfaces:

AccessibleById, AccessibleByIndex, AccessibleByName, Data, Detachable, GettableById, GettableByIndex, GettableByName, Row

public interface ReactiveRow
extends Row

A row produced by a reactive result set.

This is essentially an extension of the driver's Row object that also exposes useful information about request execution and query metadata (note however that this information is also exposed at result set level for convenience).

See Also:

ReactiveSession, ReactiveResultSet

Method Summary

Modifier and Type	Method and Description
ColumnDefinitions	getColumnDefinitions() Returns the column definitions contained in this row.
ExecutionInfo	getExecutionInfo() The execution information for the paged request that produced this result.
default boolean	wasApplied() If the query that produced this result was a conditional update, indicates whether it was successfully applied.

Method Detail

getColumnDefinitions

@NonNull
ColumnDefinitions getColumnDefinitions()

Returns the column definitions contained in this row.

This object is the same for all rows pertaining to the same result set.

Specified by:

getColumnDefinitions in interface Row

Returns:

the column definitions contained in this row.

See Also:

ReactiveQueryMetadata.getColumnDefinitions()

getExecutionInfo

@NonNull
ExecutionInfo getExecutionInfo()

The execution information for the paged request that produced this result.

This object is the same for two rows pertaining to the same page, but differs for rows pertaining to different pages.

Returns:

the execution information for the paged request that produced this result.

See Also:

ReactiveQueryMetadata.getExecutionInfos()

wasApplied

default boolean wasApplied()

If the query that produced this result was a conditional update, indicates whether it was successfully applied.

This is equivalent to calling:

 ReactiveRow row = ...
 boolean wasApplied = row.getBoolean("[applied]");
 

For consistency, this method always returns true for non-conditional queries (although there is no reason to call the method in that case). This is also the case for conditional DDL statements (CREATE KEYSPACE... IF NOT EXISTS, CREATE TABLE... IF NOT EXISTS), for which Cassandra doesn't return an [applied] column.

Note that, for versions of Cassandra strictly lower than 2.1.0-rc2, a server-side bug (CASSANDRA-7337) causes this method to always return true for batches containing conditional queries.

This method always return the same value for all results in the result set.

Returns:

true for non-conditional queries and for conditional queries that were successfully applied, false otherwise.
