Method Details

getBufferSize

public int getBufferSize()

Specified by:

getBufferSize in interface EncoderConfig

setBufferSize

public void setBufferSize(int size)

Set Encoder output buffer size.

Note: only applies when using ZstandardCompression.newEncoderSink(Content.Sink, EncoderConfig) or Compression.newEncoderSink(Content.Sink).

> Note: not applied when using ZstandardCompression.newEncoderOutputStream(OutputStream, EncoderConfig) or Compression.newEncoderOutputStream(OutputStream)

Specified by:

setBufferSize in interface EncoderConfig

Parameters:

size - size of output buffer.

getCompressionLevel

public int getCompressionLevel()

Get Zstandard encoder compression level.

Specified by:

getCompressionLevel in interface EncoderConfig

Returns:

the compression level.

setCompressionLevel

public void setCompressionLevel(int level)

Zstandard encoder compression level.

Specified by:

setCompressionLevel in interface EncoderConfig

Parameters:

level - the level to set (in range 1 to 19)

getStrategy

public int getStrategy()

Specified by:

getStrategy in interface EncoderConfig

setStrategy

public void setStrategy(int strategy)

Zstandard strategy.

Specified by:

setStrategy in interface EncoderConfig

Parameters:

strategy - the strategy to use (or -1 to use default zstd-jni strategy)
