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) throws MarshalException
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- 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 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
-
isCompatibleWith
public boolean isCompatibleWith(AbstractType<?> previous)
Description copied from class:AbstractType
Returns true if this comparator is compatible with the provided previous comparator, that is if previous can safely be replaced by this. A comparator cn should be compatible with a previous one cp if forall columns c1 and c2, if cn.validate(c1) and cn.validate(c2) and cn.compare(c1, c2) == v, then cp.validate(c1) and cp.validate(c2) and cp.compare(c1, c2) == v. Note that a type should be compatible with at least itself and when in doubt, keep the default behavior of not being compatible with any other comparator!- Overrides:
isCompatibleWith
in classAbstractType<java.nio.ByteBuffer>
-
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 classAbstractType<java.nio.ByteBuffer>
-
asCQL3Type
public CQL3Type asCQL3Type()
- Overrides:
asCQL3Type
in classAbstractType<java.nio.ByteBuffer>
-
getSerializer
public TypeSerializer<java.nio.ByteBuffer> getSerializer()
- Specified by:
getSerializer
in classAbstractType<java.nio.ByteBuffer>
