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>, AssignmentTestable

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.

<V> java.lang.String	getString(V value, ValueAccessor<V> accessor) get a string representation of the bytes used for various identifier (NOT just for log messages)
java.lang.String	toJSONString(java.nio.ByteBuffer buffer, ProtocolVersion protocolVersion) Converts the specified value into its JSON representation.

Method Detail

getInstance

public static AbstractType<?> getInstance(TypeParser parser)

compose

public <V> java.nio.ByteBuffer compose(V value,
                                       ValueAccessor<V> accessor)

Overrides:

compose in class AbstractType<java.nio.ByteBuffer>

decompose

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

Overrides:

decompose in class AbstractType<java.nio.ByteBuffer>

getString

public <V> java.lang.String getString(V value,
                                      ValueAccessor<V> accessor)

Description copied from class: AbstractType

get a string representation of the bytes used for various identifier (NOT just 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,
                                     ProtocolVersion protocolVersion)

Description copied from class: AbstractType

Converts the specified value into its JSON representation.

The buffer position will stay the same.

Overrides:

toJSONString in class AbstractType<java.nio.ByteBuffer>

Parameters:

buffer - the value to convert

protocolVersion - the protocol version to use for the conversion

Returns:

a JSON string representing the specified value

compareCustom

public <VL,VR> int compareCustom(VL left,
                                 ValueAccessor<VL> accessorL,
                                 VR right,
                                 ValueAccessor<VR> accessorR)

Description copied from class: AbstractType

Implement IFF ComparisonType is CUSTOM Compares the byte representation of two instances of this class, for types where this cannot be done by simple in-order comparison of the unsigned bytes Standard Java compare semantics

Overrides:

compareCustom in class AbstractType<java.nio.ByteBuffer>

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>
