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.

See Also:
Inflater

Variable Index

 o buf
Input buffer for decompression.
 o inf
Decompressor for this stream.
 o len
Length of input buffer.

Constructor Index

 o InflaterInputStream(InputStream)
Creates a new input stream with a default decompressor and buffer size.
 o InflaterInputStream(InputStream, Inflater)
Creates a new input stream with the specified decompressor and a default buffer size.
 o InflaterInputStream(InputStream, Inflater, int)
Creates a new input stream with the specified decompressor and buffer size.

Method Index

 o fill()
Fills input buffer with more data to decompress.
 o read()
Reads a byte of uncompressed data.
 o read(byte[], int, int)
Reads uncompressed data into an array of bytes.
 o skip(long)
Skips specified number of bytes of uncompressed data.

Variables

 o inf
Properties Inheritable 
    inf=Inflater 
Decompressor for this stream.

 o buf
Properties Inheritable 
   buf[]=byte 
Input buffer for decompression.

 o len
Properties Inheritable 
   len=int 
Length of input buffer.

Constructors

 o InflaterInputStream
    method InflaterInputStream(in=InputStream, -
                               inf=Inflater, -
                               size=int) public 
Creates a new input stream with the specified decompressor and buffer size.

Parameters:
in - the input stream
inf - the decompressor ("inflater")
len - the input buffer size
 o InflaterInputStream
    method InflaterInputStream(in=InputStream, -
                               inf=Inflater) public 
Creates a new input stream with the specified decompressor and a default buffer size.

Parameters:
in - the input stream
inf - the decompressor ("inflater")
 o InflaterInputStream
    method InflaterInputStream(in=InputStream) public 
Creates a new input stream with a default decompressor and buffer size.

Methods

 o read
    method read() returns int public     Signals 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
 o read
    method read(b=byte[], -
                off=int, -
                len=int) returns int public     Signals 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
 o skip
    method skip(n=long) returns long public     Signals 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
 o fill
    method fill()  Inheritable     Signals IOException
Fills input buffer with more data to decompress.

Throws: IOException
if an I/O error has occurred
