Method Detail

isEmptyValueMeaningless

public boolean isEmptyValueMeaningless()

Description copied from class: AbstractType

Returns true for types where empty should be handled like null like Int32Type.

Overrides:

isEmptyValueMeaningless in class AbstractType<java.math.BigInteger>

compareCustom

public int compareCustom(java.nio.ByteBuffer lhs,
                         java.nio.ByteBuffer rhs)

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.math.BigInteger>

compareIntegers

public static int compareIntegers(java.nio.ByteBuffer lhs,
                                  java.nio.ByteBuffer rhs)

fromString

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

Description copied from class: AbstractType

get a byte representation of the given string.

Specified by:

fromString in class AbstractType<java.math.BigInteger>

Throws:

MarshalException

fromJSONObject

public Term fromJSONObject(java.lang.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<java.math.BigInteger>

Parameters:

parsed - the result of parsing a json string

Throws:

MarshalException

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.math.BigInteger>

Parameters:

buffer - the value to convert

protocolVersion - the protocol version to use for the conversion

Returns:

a JSON string representing the specified value

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<java.math.BigInteger>

asCQL3Type

public CQL3Type asCQL3Type()

Overrides:

asCQL3Type in class AbstractType<java.math.BigInteger>

getSerializer

public TypeSerializer<java.math.BigInteger> getSerializer()

Specified by:

getSerializer in class AbstractType<java.math.BigInteger>
