case class ArrayType(elementType: DataType, containsNull: Boolean) extends DataType with Product with Serializable
The data type for collections of multiple values.
Internally these are represented as columns that contain a scala.collection.Seq
Please use DataTypes.createArrayType() to create a specific instance.
An ArrayType object comprises two fields, elementType: DataType and
containsNull: Boolean.
The field of elementType is used to specify the type of array elements.
The field of containsNull is used to specify if the array can have null values.
- elementType
The data type of values.
- containsNull
Indicates if the array can have
nullvalues
