case class ArrayType(elementType: DataType, containsNull: Boolean) extends DataType with Product with Serializable

:: DeveloperApi :: 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 has null values.

elementType

The data type of values.

containsNull

Indicates if values have null values
