,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.

getInstance
public static AbstractType<?> getInstance(TypeParser parser)
-
compose
public <V> java.nio.ByteBuffer compose(V value, ValueAccessor<V> accessor)
- Overrides:
compose
in classAbstractType<java.nio.ByteBuffer>
-
decompose
public java.nio.ByteBuffer decompose(java.nio.ByteBuffer value)
- Overrides:
decompose
in classAbstractType<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 classAbstractType<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 classAbstractType<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 classAbstractType<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 classAbstractType<java.nio.ByteBuffer>
- Parameters:
buffer
- the value to convertprotocolVersion
- 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 classAbstractType<java.nio.ByteBuffer>
-
validate
public void validate(java.nio.ByteBuffer bytes) throws MarshalException
- Overrides:
validate
in classAbstractType<java.nio.ByteBuffer>
- Throws:
MarshalException
-
getSerializer
public TypeSerializer<java.nio.ByteBuffer> getSerializer()
- Specified by:
getSerializer
in classAbstractType<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 classAbstractType<java.nio.ByteBuffer>
