Class InflaterInputStream
- Closeable
This filter stream is used to decompress data compressed in the "deflate"
format. The "deflate" format is described in RFC 1951.
This stream may form the basis for other decompression filters, such
as the GZIPInputStream.
protected byte[] | buf- Byte array used as a buffer
|
protected Inflater | inf- Decompressor for this filter
|
protected int | len- Size of buffer
|
int | available()- Returns 0 once the end of the stream (EOF) has been reached.
|
void | close()- Closes the input stream
|
protected void | fill()- Fills the buffer with more data to decompress.
|
void | mark(int readLimit)
|
boolean | markSupported()
|
int | read()- Reads one byte of decompressed data.
|
int | read(byte[] b, int off, int len)- Decompresses data into the byte array
|
void | reset()
|
long | skip(long n)- Skip specified number of bytes of uncompressed data

public InflaterInputStream(InputStream in)
Create an InflaterInputStream with the default decompresseor
and a default buffer size.
in - the InputStream to read bytes from
InflaterInputStream

InflaterInputStream
public InflaterInputStream(InputStream in,
Inflater inf,

fill
protected void fill()
throws IOException Fills the buffer with more data to decompress.
