Package org.apache.cassandra.db.rows

Class AbstractRow

java.lang.Object

org.apache.cassandra.db.rows.AbstractRow

All Implemented Interfaces:

java.lang.Iterable<ColumnData>, IMeasurableMemory, Clusterable, Row, Unfiltered

Direct Known Subclasses:

BTreeRow

public abstract class AbstractRow
extends java.lang.Object
implements Row

Base abstract class for Row implementations. Unless you have a very good reason not to, every row implementation should probably extend this class.

Method Detail

kind

public Unfiltered.Kind kind()

Description copied from interface: Unfiltered

The kind of the atom: either row or range tombstone marker.

Specified by:

kind in interface Unfiltered

hasLiveData

public boolean hasLiveData(long nowInSec,
                           boolean enforceStrictLiveness)

Description copied from interface: Row

Whether the row has some live information (i.e. it's not just deletion informations).

Specified by:

hasLiveData in interface Row

Parameters:

nowInSec - the current time to decide what is deleted and what isn't

enforceStrictLiveness - whether the row should be purged if there is no PK liveness info, normally retrieved from TableMetadata.enforceStrictLiveness()

Returns:

true if there is some live information

isStatic

public boolean isStatic()

Description copied from interface: Row

Whether the row correspond to a static row or not.

Specified by:

isStatic in interface Row

Returns:

whether the row correspond to a static row or not.

digest

public void digest(Digest digest)

Description copied from interface: Unfiltered

Digest the atom using the provided Digest.

Specified by:

digest in interface Unfiltered

Parameters:

digest - the {@see Digest} to use.

validateData

public void validateData(TableMetadata metadata)

Description copied from interface: Unfiltered

Validate the data of this atom.

Specified by:

validateData in interface Unfiltered

Parameters:

metadata - the metadata for the table this atom is part of.

hasInvalidDeletions

public boolean hasInvalidDeletions()

Description copied from interface: Unfiltered

Do a quick validation of the deletions of the unfiltered (if any)

Specified by:
