freezeNestedMulticellTypes
public AbstractType<?> freezeNestedMulticellTypes()
Description copied from class:AbstractType
Returns an AbstractType instance that is equivalent to this one, but with all nested UDTs and collections explicitly frozen. This is only necessary for2.x -> 3.x
schema migrations, and can be removed in Cassandra 4.0. See CASSANDRA-11609 and CASSANDRA-11613.- Overrides:
freezeNestedMulticellTypes
in classAbstractType<java.util.Set<T>>
-
isCompatibleWithFrozen
public boolean isCompatibleWithFrozen(CollectionType<?> previous)
Description copied from class:CollectionType
A version of isCompatibleWith() to deal with non-multicell (frozen) collections- Specified by:

in classCollectionType<java.util.Set<T>>
-
isValueCompatibleWithFrozen
public boolean isValueCompatibleWithFrozen(CollectionType<?> previous)
Description copied from class:CollectionType

Description copied from class:AbstractType
Given a parsed JSON string, return a byte representation of the object.- Specified by:
fromJSONObject
in classAbstractType<java.util.Set<T>>
- Parameters:

toJSONString
public java.lang.String toJSONString(java.nio.ByteBuffer buffer, ProtocolVersion protocolVersion)
Description copied from class:AbstractType
