Examples of java.util.zip.Inflater.inflate()

java.util.zip.Inflater.inflate()
Uncompresses bytes into specified buffer. Returns actual number of bytes uncompressed. A return value of 0 indicates that needsInput() or needsDictionary() should be called in order to determine if more input data or a preset dictionary is required. In the latter case, getAdler() can be used to get the Adler-32 value of the dictionary required. @param b the buffer for the uncompressed data @param off the start offset of the data @param len the maximum number of uncompressed bytes @return the actual number of uncompressed bytes @exception DataFormatException if the compressed data format is invalid @see Inflater#needsInput @see Inflater#needsDictionary
