Method Details

getSubtype

public DataType getSubtype()

getDimensions

public int getDimensions()

getTypeArguments

public List<DataType> getTypeArguments()

Description copied from class: DataType

Returns the type arguments of this type.

Note that only the collection types (LIST, MAP, SET) have type arguments. For the other types, this will return an empty list.

For the collection types:

• For lists and sets, this method returns one argument, the type of the elements.
• For maps, this method returns two arguments, the first one is the type of the map keys, the second one is the type of the map values.

Overrides:

getTypeArguments in class DataType

Returns:

an immutable list containing the type arguments of this type.

isFrozen

public boolean isFrozen()

Description copied from class: DataType

Returns whether this data type is frozen.

This applies to User Defined Types, tuples and nested collections. Frozen types are serialized as a single value in Cassandra's storage engine, whereas non-frozen types are stored in a form that allows updates to individual subfields.

Specified by:

isFrozen in class DataType

Returns:

whether this data type is frozen.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
