java.util.zip - InflaterInputStream Class

Introduction

The java.util.zip.InflaterInputStream 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.

Class declaration

Following is the declaration for java.util.zip.InflaterInputStream class −

pubpc class InflaterInputStream
   extends FilterInputStream

Fields

Following are the fields for java.util.zip.InflaterInputStream class −

protected byte[] buf − Input buffer for decompression.

protected Inflater inf − Decompressor for this stream.

protected int len − Length of input buffer.

Constructors

Sr.No.	Constructor & Description
1	InflaterInputStream(InputStream in) Creates a new input stream with a default decompressor and buffer size.
2	InflaterInputStream(InputStream in, Inflater inf) Creates a new input stream with the specified decompressor and a default buffer size.
3	InflaterInputStream(InputStream in, Inflater inf, int size) Creates a new input stream with the specified decompressor and buffer size.

Class methods

Sr.No.	Method & Description
1	int available() Returns 0 after EOF has been reached, otherwise always return 1.
2	void close() Closes this input stream and releases any system resources associated with the stream.
3	void mark(int readpmit) Marks the current position in this input stream.
4	boolean markSupported() Tests if this input stream supports the mark and reset methods.
5	int read() Reads a byte of uncompressed data.
6	int read(byte[] b, int off, int len) Reads uncompressed data into an array of bytes.
7	void reset() Repositions this stream to the position at the time the mark method was last called on this input stream.
8	long skip(long n) Skips specified number of bytes of uncompressed data.
