Method Details

create

public PrimaryKey create(Token token)

Creates a PrimaryKey that is represented by a Token.

Token only primary keys are used for defining the partition range of a query.

create

public PrimaryKey create(DecoratedKey partitionKey)

Create a PrimaryKey for tables without clustering columns

create

public PrimaryKey create(DecoratedKey partitionKey,
 Clustering<?> clustering)

Creates a PrimaryKey that is fully represented by partition key and clustering.

hasClusteringColumns

public boolean hasClusteringColumns()

fromComparableBytes

public PrimaryKey fromComparableBytes(ByteSource byteSource)

Create a PrimaryKey from a ByteSource. This should only be used with ByteSource instances created by calls to PrimaryKey.asComparableBytes(Version).

partitionKeyFromComparableBytes

public DecoratedKey partitionKeyFromComparableBytes(ByteSource byteSource)

Create a DecoratedKey from a ByteSource. This is a separate method because of it's use by the PrimaryKeyMap implementations to create partition keys.

clusteringFromByteComparable

public Clustering<?> clusteringFromByteComparable(ByteSource byteSource)

Create a Clustering from a ByteSource. This is a separate method because of its use by the WidePrimaryKeyMap to create its clustering keys.
