Constructors
XzArchiveSettings()
Initializes a new instance of the Aspose.Zip.Xz.Settings.XzArchiveSettings class using single LZMA2 compression.
public XzArchiveSettings()Remarks
Default dictionary in LZMA2 filter size equals to 16 megabyte, default block size equals to 64 megabytes, default checksum type is CRC32.
XzArchiveSettings(XzFilterSettings[], long, XzCheckType)
Initializes a new instance of the Aspose.Zip.Xz.Settings.XzArchiveSettings class with custom parameters.
public XzArchiveSettings(XzFilterSettings[] filters, long blockSize, XzCheckType checkType)Parameters
filters XzFilterSettings[]
Filters (compressors) to be sequentially applied to create Aspose.Zip.Xz.XzArchive. It can be either single Aspose.Zip.Xz.Settings.XzLZMA2FilterSettings or pair of Aspose.Zip.Xz.Settings.XzBcjX86FilterSettings and Aspose.Zip.Xz.Settings.XzLZMA2FilterSettings
blockSize long
Size xz archive block.
checkType XzCheckType
Type of checksum calculation for uncompressed data.
Examples
using (FileStream xzFile = File.Open("archive.xz", FileMode.Create))
{
XzLZMA2FilterSettings filter = new XzLZMA2FilterSettings(5242880);
XzArchiveSettings settings = new XzArchiveSettings(new XzFilterSettings[] {filter}, 10485760, XzCheckType.Crc32);
using (var archive = new XzArchive(settings))
{
archive.SetSource("data.bin");
archive.Save(xzFile);
}
}Exceptions
blockSize is negative.
filters is null
filters has less than one or more than two filter, or last filter is not Aspose.Zip.Xz.Settings.XzLZMA2FilterSettings.
