Method Detail

isSorted

public boolean isSorted()

Description copied from interface: Row.Builder

Whether the builder is a sorted one or not.

Specified by:

isSorted in interface Row.Builder

Returns:

if the builder requires calls to be done in sorted order or not (see above).

newRow

public void newRow(Clustering clustering)

Description copied from interface: Row.Builder

Prepares the builder to build a new row of clustering clustering.

This should always be the first call for a given row.

Specified by:

newRow in interface Row.Builder

Parameters:

clustering - the clustering for the new row.

clustering

public Clustering clustering()

Description copied from interface: Row.Builder

The clustering for the row that is currently being built.

Specified by:

clustering in interface Row.Builder

Returns:

the clustering for the row that is currently being built, or null if Row.Builder.newRow(org.apache.cassandra.db.Clustering) hasn't yet been called.

reset

protected void reset()

addPrimaryKeyLivenessInfo

public void addPrimaryKeyLivenessInfo(LivenessInfo info)

Description copied from interface: Row.Builder

Adds the liveness information for the primary key columns of this row. This call is optional (skipping it is equivalent to calling addPartitionKeyLivenessInfo(LivenessInfo.NONE)).

Specified by:

addPrimaryKeyLivenessInfo in interface Row.Builder

Parameters:

info - the liveness information for the primary key columns of the built row.

addRowDeletion

public void addRowDeletion(Row.Deletion deletion)

Description copied from interface: Row.Builder

Adds the deletion information for this row. This call is optional and can be skipped if the row is not deleted.

Specified by:

addRowDeletion in interface Row.Builder

Parameters:

deletion - the row deletion time, or Deletion.LIVE if the row isn't deleted.

addCell

public void addCell(Cell cell)

Description copied from interface: Row.Builder

Adds a cell to this builder.

Specified by:

addCell in interface Row.Builder

Parameters:

cell - the cell to add.

addComplexDeletion

public void addComplexDeletion(ColumnDefinition column,
                               DeletionTime complexDeletion)

Description copied from interface: Row.Builder

Adds a complex deletion.

Specified by:

addComplexDeletion in interface Row.Builder

Parameters:

column - the column for which to add the complexDeletion.

complexDeletion - the complex deletion time to add.

build

public Row build()

Description copied from interface: Row.Builder

Builds and return built row.

Specified by:

build in interface Row.Builder

Returns:

the last row built by this builder.
