DefaultStructVector

public DefaultStructVector(int size,
 io.delta.kernel.types.DataType dataType,
 Optional<boolean[]> nullability,
 io.delta.kernel.data.ColumnVector[] memberVectors)

Create an instance of ColumnVector for struct type.

Parameters:

size - number of elements in the vector.

dataType - struct datatype definition.

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.

memberVectors - column vectors for each member of the struct.
