@Namespace(value="arrow") @NoOffset @Properties(inherit=arrow.class) public class DenseUnionBuilder extends BasicUnionBuilder
Pointer.CustomDeallocator, Pointer.Deallocator, Pointer.NativeDeallocator, Pointer.ReferenceCounter| Constructor and Description |
|---|
DenseUnionBuilder(MemoryPool pool)
Use this constructor to initialize the UnionBuilder with no child builders,
allowing type to be inferred.
|
DenseUnionBuilder(MemoryPool pool,
ArrayBuilderVector children,
DataType type)
Use this constructor to specify the type explicitly.
|
DenseUnionBuilder(Pointer p)
Pointer cast constructor.
|
| Modifier and Type | Method and Description |
|---|---|
Status |
Append(byte next_type)
\brief Append an element to the UnionArray.
|
Status |
AppendArraySlice(ArrayData array,
long offset,
long length)
\brief Append a range of values from an array.
|
Status |
AppendEmptyValue()
\brief Append a non-null value to builder
The appended value is an implementation detail, but the corresponding
memory slot is guaranteed to be initialized.
|
Status |
AppendEmptyValues(long length)
\brief Append a number of non-null values to builder
The appended values are an implementation detail, but the corresponding
memory slot is guaranteed to be initialized.
|
Status |
AppendNull()
\brief Append a null value to builder
|
Status |
AppendNulls(long length)
\brief Append a number of null values to builder
|
Status |
FinishInternal(ArrayData out)
\brief Return result of builder as an internal generic ArrayData
object.
