Constructor Detail

WriteProperties

public WriteProperties()

Default native constructor.

WriteProperties

public WriteProperties(long size)

Native array allocator. Access with Pointer.position(long).

WriteProperties

public WriteProperties(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

position

public WriteProperties position(long position)

Overrides:

position in class Pointer

getPointer

public WriteProperties getPointer(long i)

Overrides:

getPointer in class Pointer

Defaults

@ByVal
public static WriteProperties Defaults()

DefaultsV1

@ByVal
public static WriteProperties DefaultsV1()

version

public int version()

Feather file version number version 2: "Feather V1" Apache Arrow <= 0.16.0 version 3: "Feather V2" Apache Arrow > 0.16.0

version

public WriteProperties version(int setter)

chunksize

@Cast(value="int64_t")
public long chunksize()

Number of rows per intra-file chunk. Use smaller chunksize when you need faster random row access

chunksize

public WriteProperties chunksize(long setter)

compression

public Compression.type compression()

Compression type to use. Only UNCOMPRESSED, LZ4_FRAME, and ZSTD are supported. The default compression returned by Defaults() is LZ4 if the project is built with support for it, otherwise UNCOMPRESSED. UNCOMPRESSED is set as the object default here so that if WriteProperties::Defaults() is not used, the default constructor for WriteProperties will work regardless of the options used to build the C++ project.

compression

public WriteProperties compression(Compression.type setter)

compression_level

public int compression_level()

Compressor-specific compression level

compression_level

public WriteProperties compression_level(int setter)
