Method Detail

factory

public Lz4FrameDecompressor.Builder factory(net.jpountz.lz4.LZ4Factory factory)

User customizable LZ4Factory instance which may be JNI bindings to the original C implementation, a pure Java implementation or a Java implementation that uses the Unsafe.

Parameters:

factory - The factory to use

Returns:

This builder

checksum

public Lz4FrameDecompressor.Builder checksum(java.util.zip.Checksum checksum)

The Checksum instance to use to check data for integrity. By default, no checksum validation is performed.

Parameters:

checksum - The checksum to use

Returns:

This builder

defaultChecksum

public Lz4FrameDecompressor.Builder defaultChecksum()

Enable checksum validation using the default checksum, xxhash.

Returns:

This builder

maxDecompressedLength

public Lz4FrameDecompressor.Builder maxDecompressedLength(int maxDecompressedLength)

Set the maximum allowed decompressed block length. The default is 256 KiB. Use 0 to allow the LZ4 format maximum of 32 MiB.

Parameters:

maxDecompressedLength - maximum decompressed block length

Returns:

This builder

build

public Decompressor build(ByteBufAllocator allocator)
                   throws DecompressionException

Specified by:

build in class Decompressor.AbstractDecompressorBuilder

Throws:

DecompressionException
