This class implements a stream filter for uncompressing data in the “deflate” compression format. It is also used as the basis for other decompression filters, such as GZIPInputStream.
- InflaterInputStream(InputStream in) : Creates a new input stream with a default decompressor and buffer size.
- InflaterInputStream(InputStream in, Inflater inf) : Creates a new input stream with the specified decompressor and a default buffer size.
- InflaterInputStream(InputStream in, Inflater inf, int size) : Creates a new input stream with the specified decompressor and buffer size.
- int available() : Returns 0 after EOF has been reached, otherwise always return 1.
Syntax : public int available() throws IOException Returns: 1 before EOF and 0 after EOF. Throws: IOException
- void close() : Closes this input stream and releases any system resources associated with the stream.
Syntax : public void close() throws IOException Throws: IOException
- protected void fill() : Fills input buffer with more data to decompress.
Syntax : protected void fill() throws IOException Throws: IOException
- void mark(int readlimit) : Marks the current position in this input stream.
Syntax : public void mark(int readlimit) Parameters: readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
- boolean markSupported() : Tests if this input stream supports the mark and reset methods.
Syntax : public boolean markSupported() Returns: a boolean indicating if this stream type supports the mark and reset methods.
- int read() : Reads a byte of uncompressed data.
Syntax : public int read() throws IOException Returns: the byte read, or -1 if end of compressed input is reached Throws: IOException
- int read(byte b, int off, int len) : Reads uncompressed data into an array of bytes.
Syntax : public int read(byte b, int off, int len) throws IOException Parameters: b - the buffer into which the data is read off - the start offset in the destination array b len - the maximum number of bytes read Returns: the actual number of bytes read, or -1 if the end of the compressed input is reached. Throws: NullPointerException IndexOutOfBoundsException ZipException IOException
- void reset() : Repositions this stream to the position at the time the mark method was last called on this input stream.
Syntax : public void reset() throws IOException Throws: IOException
- long skip(long n) : Skips specified number of bytes of uncompressed data.
Syntax : public long skip(long n) throws IOException Parameters: n - the number of bytes to skip Returns: the actual number of bytes skipped. Throws: IOException IllegalArgumentException
