All Implemented Interfaces:

Comparator<ByteBuffer>, AssignmentTestable

public class DurationType
extends AbstractType<Duration>

Represents a duration. The duration is stored as months, days, and nanoseconds. This is done

Internally he duration is stored as months (unsigned integer), days (unsigned integer), and nanoseconds.

Method Details

fromString

public ByteBuffer fromString(String source)
                      throws MarshalException

Description copied from class: AbstractType

get a byte representation of the given string.

Specified by:

fromString in class AbstractType<Duration>

Throws:

MarshalException

isValueCompatibleWithInternal

public boolean isValueCompatibleWithInternal(AbstractType<?> otherType)

Description copied from class: AbstractType

Needed to handle ReversedType in value-compatibility checks. Subclasses should implement this instead of isValueCompatibleWith().

Overrides:

isValueCompatibleWithInternal in class AbstractType<Duration>

fromJSONObject

public Term fromJSONObject(Object parsed)
                    throws MarshalException

Description copied from class: AbstractType

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

Specified by:

fromJSONObject in class AbstractType<Duration>

Parameters:

parsed - the result of parsing a json string

Throws:

MarshalException

getSerializer

public TypeSerializer<Duration> getSerializer()

Specified by:

getSerializer in class AbstractType<Duration>

getArgumentDeserializer

public ArgumentDeserializer getArgumentDeserializer()

Overrides:

getArgumentDeserializer in class AbstractType<Duration>

Returns:

the deserializer used to deserialize the function arguments of this type.

asCQL3Type

public CQL3Type asCQL3Type()

Overrides:

asCQL3Type in class AbstractType<Duration>

referencesDuration

public boolean referencesDuration()

Overrides:

referencesDuration in class AbstractType<Duration>

getMaskedValue

public ByteBuffer getMaskedValue()

Overrides:

getMaskedValue in class AbstractType<Duration>

Returns:

A fixed, serialized value to be used when the column is masked, to be returned instead of the real value.
