InflaterInputStreamjava.util.zip

Java 1.1closeable

This class is a subclass of java.io.FilterInputStream; it reads a specified stream of compressed input data (typically one that was written with DeflaterOutputStream or a subclass) and filters that data by uncompressing (inflating) it. To create an InflaterInputStream, specify both the input stream to read from and an Inflater object to perform the decompression. Once an InflaterInputStream is created, the read( ) and skip( ) methods are the same as those of other input streams. The InflaterInputStream uncompresses raw data. Applications often prefer one of its subclasses, GZIPInputStream or ZipInputStream, that work with compressed data written in the standard

gzip and

PKZip file formats.
