Constructor Details

DefaultArrayVector

public DefaultArrayVector(int size,
 io.delta.kernel.types.DataType type,
 Optional<boolean[]> nullability,
 int[] offsets,
 io.delta.kernel.data.ColumnVector elementVector)

Create an instance of ColumnVector for array type.

Parameters:

size - number of elements in the vector.

nullability - Optional array of nullability value for each element in the vector. All values in the vector are considered non-null when parameter is empty.

offsets - Offsets into element vector on where the index of particular row values start and end.

elementVector - Vector containing the array elements.

Method Details

getArray

public io.delta.kernel.data.ArrayValue getArray(int rowId)

Get the value at given rowId. The return value is undefined and can be anything, if the slot for rowId is null.

Specified by:

getArray in interface io.delta.kernel.data.ColumnVector

Overrides:

getArray in class AbstractColumnVector

Parameters:

rowId -

Returns:
