public UnionArray getPointer(long i)

Overrides:

getPointer in class Pointer

type_codes

@SharedPtr
public ArrowBuffer type_codes()

Note that this buffer does not account for any slice offset

raw_type_codes

@Cast(value="const arrow::UnionArray::type_code_t*")
public BytePointer raw_type_codes()

child_id

public int child_id(@Cast(value="int64_t")
                    long i)

The physical child id containing value at index.

union_type

@Const
public UnionType union_type()

mode

public UnionMode.type mode()

child

@Deprecated
 @SharedPtr

public Array child(int pos)

Deprecated.

field

@SharedPtr
 @Cast(value={"","std::shared_ptr<arrow::Array>"})
public Array field(int pos)

\brief Return the given field as an individual array. For sparse unions, the returned array has its offset, length and null count adjusted.
