LZMACompressorInputStream
Creates a new input stream that decompresses LZMA-compressed data from the specified input stream.- Parameters:
inputStream- where to read the compressed data- Throws:
IOException- if the input is not in the .lzma format, the input is corrupt or truncated, the .lzma headers specify sizes that are not supported by this implementation, or the underlyinginputStreamthrows an exception
