Package Summary  Overview Summary

class:InflaterInputStream [NONE]

  • All Implemented Interfaces:
    Closeable, AutoCloseable
    Direct Known Subclasses:
    GZIPInputStream, ZipInputStream

    public class InflaterInputStream
    extends FilterInputStream
    
    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.
    Since:
    1.1
    See Also:
    Inflater

field:inf [NONE]

  • inf

    protected Inflater inf
    Decompressor for this stream.

field:buf [NONE]

  • buf

    protected byte[] buf
    Input buffer for decompression.

field:len [NONE]

  • len

    protected int len
    Length of input buffer.

constructor:<init>(java.io.InputStream,java.util.zip.Inflater,int) [NONE]

  • InflaterInputStream

    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
    Throws:
    IllegalArgumentException - if size <= 0

constructor:<init>(java.io.InputStream,java.util.zip.Inflater) [NONE]

  • InflaterInputStream

    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")

constructor:<init>(java.io.InputStream) [NONE]

  • InflaterInputStream

    public InflaterInputStream​(InputStream in)
    Creates a new input stream with a default decompressor and buffer size.
    Parameters:
    in - the input stream

method:read() [NONE]

  • read

    public int read()
             throws IOException
    
    Reads a byte of uncompressed data. This method will block until enough input is available for decompression.
    Overrides:
    read in class FilterInputStream
    Returns:
    the byte read, or -1 if end of compressed input is reached
    Throws:
    IOException - if an I/O error has occurred
    See Also:
    FilterInputStream.in

method:read(byte[],int,int) [NONE]

  • read

    public int read​(byte[] b,
                    int off,
                    int len)
             throws IOException
    
    Reads uncompressed data into an array of bytes. If len is not zero, the method will block until some input can be decompressed; otherwise, no bytes are read and 0 is returned.
    Overrides:
    read in class FilterInputStream
    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 or a preset dictionary is needed
    Throws:
    NullPointerException - If b is null.
    IndexOutOfBoundsException - If off is negative, len is negative, or len is greater than b.length - off
    ZipException - if a ZIP format error has occurred
    IOException - if an I/O error has occurred
    See Also:
    FilterInputStream.in

method:available() [NONE]

  • available

    public int available()
                  throws IOException
    
    Returns 0 after EOF has been reached, otherwise always return 1.

    Programs should not count on this method to return the actual number of bytes that could be read without blocking.

    Overrides:
    available in class FilterInputStream
    Returns:
    1 before EOF and 0 after EOF.
    Throws:
    IOException - if an I/O error occurs.

method:skip(long) [CHANGED]

method:close() [NONE]

method:fill() [NONE]

  • fill

    protected void fill()
                 throws IOException
    
    Fills input buffer with more data to decompress.
    Throws:
    IOException - if an I/O error has occurred

method:markSupported() [NONE]

  • markSupported

    public boolean markSupported()
    Tests if this input stream supports the mark and reset methods. The markSupported method of InflaterInputStream returns false.
    Overrides:
    markSupported in class FilterInputStream
    Returns:
    a boolean indicating if this stream type supports the mark and reset methods.
    See Also:
    InputStream.mark(int), InputStream.reset()

method:mark(int) [NONE]

  • mark

    public void mark​(int readlimit)
    Marks the current position in this input stream.

    The mark method of InflaterInputStream does nothing.

    Overrides:
    mark in class FilterInputStream
    Parameters:
    readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
    See Also:
    InputStream.reset()

method:reset() [NONE]

  • reset

    public void reset()
               throws IOException
    
    Repositions this stream to the position at the time the mark method was last called on this input stream.

    The method reset for class InflaterInputStream does nothing except throw an IOException.

    Overrides:
    reset in class FilterInputStream
    Throws:
    IOException - if this method is invoked.
    See Also:
    InputStream.mark(int), IOException
