public class InflaterInputStream

extends FilterInputStream

See Also:

Inflater

buf

Input buffer for decompression.

inf

Decompressor for this stream.

len

Length of input buffer.

InflaterInputStream(InputStream)

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

InflaterInputStream(InputStream, Inflater)

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

InflaterInputStream(InputStream, Inflater, int)

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

fill()

Fills input buffer with more data to decompress.

read()

Reads a byte of uncompressed data.

read(byte[], int, int)

Reads uncompressed data into an array of bytes.

skip(long)

Skips specified number of bytes of uncompressed data.

protected Inflater inf

Decompressor for this stream.

protected byte buf[]

Input buffer for decompression.

protected int len

Length of input buffer.

public InflaterInputStream(InputStream in,
Inflater inf,
                            int size)

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

Parameters:

in - the input stream

inf - the decompressor ("inflater")

size - the input buffer size

public InflaterInputStream(InputStream in,
Inflater inf)

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

Parameters:

in - the input stream

inf - the decompressor ("inflater")

public InflaterInputStream(InputStream in)

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

public int read() throws IOException

Reads a byte of uncompressed data. This method will block until enough input is available for decompression.

Returns:

the byte read, or -1 if end of compressed input is reached

Throws: IOException

if an I/O error has occurred

Overrides:

read in class FilterInputStream

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

Reads uncompressed data into an array of bytes. This method will block until some input can be decompressed.

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

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 or a preset dictionary is needed

Throws: ZipException

if a ZIP format error has occurred

Throws: IOException

if an I/O error has occurred

Overrides:

read in class FilterInputStream

public long skip(long n) throws IOException

Skips specified number of bytes of uncompressed data.

Parameters:

n - the number of bytes to skip

Returns:

the actual number of bytes skipped.

Throws: IOException

if an I/O error has occurred

Overrides:

skip in class FilterInputStream

protected void fill() throws IOException

Fills input buffer with more data to decompress.

Throws: IOException

if an I/O error has occurred
