java.util.zip - DeflaterInputStream Class

Introduction

The java.util.zip.DeflaterInputStream class implements an input stream filter for compressing data in the "deflate" compression format.

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

pubpc class DeflaterInputStream
   extends FilterInputStream

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

protected byte[] buf − Input buffer for reading compressed data.

protected Deflater def − Compressor for this stream.

Sr.No.	Constructor & Description
1	DeflaterInputStream(InputStream in) Creates a new input stream with a default compressor and buffer size.
2	DeflaterInputStream(InputStream in, Deflater defl) Creates a new input stream with the specified compressor and a default buffer size.
3	DeflaterInputStream(InputStream in, Deflater defl, int bufLen) Creates a new input stream with the specified compressor and buffer size.

Sr.No.

Constructor & Description

DeflaterInputStream(InputStream in)

Creates a new input stream with a default compressor and buffer size.

DeflaterInputStream(InputStream in, Deflater defl)

Creates a new input stream with the specified compressor and a default buffer size.

DeflaterInputStream(InputStream in, Deflater defl, int bufLen)

Creates a new input stream with the specified compressor and buffer size.

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 its underlying input stream, discarding any pending uncompressed data.
3	int read() Reads a single byte of compressed data from the input stream.
4	int read(byte[] b, int off, int len) Reads compressed data into a byte array.
5	long skip(long n) Skips over and discards data from the input stream.
