Description¶

TDecompressionStream performs the inverse operation of TCompressionStream. A read operation reads data from an input stream and decompresses (inflates) the data it as it goes along.

The decompression stream reads it's compressed data from a stream with deflated data. This data can be created e.g. with a TCompressionStream compression stream.
