Constructor Detail

PartitioningFactory

public PartitioningFactory(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

type_name

@StdString
public String type_name()

\brief The name identifying the kind of partitioning

Inspect

@ByVal
public SchemaResult Inspect(@Const @ByRef
                                    StringVector paths)

Get the schema for the resulting Partitioning. This may reset internal state, for example dictionaries of unique representations.

Finish

@ByVal
public PartitioningResult Finish(@Const @SharedPtr @ByRef
                                         Schema schema)

Create a partitioning using the provided schema (fields may be dropped).
