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 Summary

Modifier and Type	Method and Description
int	compareCustom(java.nio.ByteBuffer o1, java.nio.ByteBuffer o2) Implement IFF ComparisonType is CUSTOM Compares the ByteBuffer 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
java.nio.ByteBuffer	compose(java.nio.ByteBuffer bytes)
java.nio.ByteBuffer	decompose(java.nio.ByteBuffer bytes)
Term	fromJSONObject(java.lang.Object parsed) Given a parsed JSON string, return a byte representation of the object.
java.nio.ByteBuffer	fromString(java.lang.String source) get a byte representation of the given string.
static AbstractType<?>	getInstance(TypeParser parser)
TypeSerializer<java.nio.ByteBuffer>	getSerializer()
java.lang.String	getString(java.nio.ByteBuffer bytes) get a string representation of the bytes used for various identifier (NOT just for log messages)
java.lang.String	toJSONString(java.nio.ByteBuffer buffer, int protocolVersion) Converts a value to a JSON string.
java.lang.String	toString() This must be overriden by subclasses if necessary so that for any AbstractType, this == TypeParser.parse(toString()).

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 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,
                                     int protocolVersion)

Description copied from class: AbstractType

Converts a value to a JSON string.

Overrides:

toJSONString in class AbstractType<java.nio.ByteBuffer>

compareCustom

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

Description copied from class: AbstractType

Implement IFF ComparisonType is CUSTOM Compares the ByteBuffer 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>
