DeflaterInputStream JDK 1.6)

Constructors

public DeflaterInputStream (InputStream in)

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

public DeflaterInputStream (InputStream in, Deflater defl)

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

public DeflaterInputStream (InputStream in, Deflater defl, int bufLen)

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

Methods

Hide/Show inherited methods

public int available () throws IOException [Overrides FilterInputStream]

Returns 0 after EOF has been reached, otherwise always return 1.

public void close () throws IOException [Overrides FilterInputStream]

Closes this input stream and its underlying input stream, discarding any pending uncompressed data.

public void mark (int limit) [Overrides FilterInputStream]

This operation is not supported.

public boolean markSupported () [Overrides FilterInputStream]

Always returns false because this input stream does not support the mark() and reset() methods.

Always returns false because this input stream does not support
the mark() and reset() methods.
Returns: false, always

public int read () throws IOException [Overrides FilterInputStream] [Specified in InputStream]

Reads a single byte of compressed data from the input stream.

public int read (byte[] b) throws IOException [Inherited From FilterInputStream]

Reads up to byte.length bytes of data from this input stream into an array of bytes.

Reads up to byte.length bytes of data from this input stream into an array of bytes. This method blocks until some input is available.

This method simply performs the call read(b, 0, b.length) and returns the result. It is important that it does not do in.read(b) instead; certain subclasses of FilterInputStream depend on the implementation strategy actually used.
Returns: the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
Parameters:
- b - the buffer into which the data is read.
Throws:
- IOException - if an I/O error occurs.

public int read (byte[] b, int off, int len) throws IOException [Overrides FilterInputStream]

Reads compressed data into a byte array.

public void reset () throws IOException [Overrides FilterInputStream]

This operation is not supported.

public long skip (long n) throws IOException [Overrides FilterInputStream]

Skips over and discards data from the input stream.

Skips over and discards data from the input stream.
This method may block until the specified number of bytes are read and
skipped. Note: While n is given as a long,
the maximum number of bytes which can be skipped is
Integer.MAX_VALUE.
Returns: the actual number of bytes skipped
Parameters:
- n - number of bytes to be skipped
Throws:
- IOException - if an I/O error occurs or if this stream is already closed
