Class PartitionerDefinedOrder

java.lang.Object

org.apache.cassandra.db.marshal.AbstractType<java.nio.ByteBuffer>

org.apache.cassandra.db.marshal.PartitionerDefinedOrder

All Implemented Interfaces:

java.util.Comparator<java.nio.ByteBuffer>

public class PartitionerDefinedOrder
extends AbstractType<java.nio.ByteBuffer>

for sorting columns representing row keys in the row ordering as determined by a partitioner. Not intended for user-defined CFs, and will in fact error out if used with such.

Method Detail

getInstance

public static AbstractType<?> getInstance(TypeParser parser)

compose

public java.nio.ByteBuffer compose(java.nio.ByteBuffer bytes)

Overrides:

compose in class AbstractType<java.nio.ByteBuffer>

decompose

public java.nio.ByteBuffer decompose(java.nio.ByteBuffer bytes)

Overrides:

decompose in class AbstractType<java.nio.ByteBuffer>

getString

public java.lang.String getString(java.nio.ByteBuffer bytes)

Description copied from class: AbstractType

get a string representation of the bytes suitable for log messages

Overrides:

getString in class AbstractType<java.nio.ByteBuffer>

fromString

public java.nio.ByteBuffer fromString(java.lang.String source)

Description copied from class: AbstractType

get a byte representation of the given string.

Specified by:

fromString in class AbstractType<java.nio.ByteBuffer>

fromJSONObject

public Term fromJSONObject(java.lang.Object parsed)

Description copied from class: AbstractType

Given a parsed JSON string, return a byte representation of the object.

Specified by:

fromJSONObject in class AbstractType<java.nio.ByteBuffer>

Parameters:

parsed - the result of parsing a json string

toJSONString

public java.lang.String toJSONString(java.nio.ByteBuffer buffer,
                                     int protocolVersion)

Description copied from class: AbstractType

Converts a value to a JSON string.

Overrides:

toJSONString in class AbstractType<java.nio.ByteBuffer>

compare

public int compare(java.nio.ByteBuffer o1,
                   java.nio.ByteBuffer o2)

validate

public void validate(java.nio.ByteBuffer bytes)
              throws MarshalException

Overrides:

validate in class AbstractType<java.nio.ByteBuffer>

Throws:

MarshalException

getSerializer

public TypeSerializer<java.nio.ByteBuffer> getSerializer()

Specified by:

getSerializer in class AbstractType<java.nio.ByteBuffer>

toString

public java.lang.String toString()

Description copied from class: AbstractType

This must be overriden by subclasses if necessary so that for any AbstractType, this == TypeParser.parse(toString()). Note that for backwards compatibility this includes the full classname. For CQL purposes the short name is fine.

Overrides:

toString in class AbstractType<java.nio.ByteBuffer>
