in| Constructor and Description |
|---|
DeflaterInputStream(InputStream in)
Creates a new input stream with a default compressor and buffer
size.
|
DeflaterInputStream(InputStream in,
Deflater defl)
Creates a new input stream with the specified compressor and a
default buffer size.

DeflaterInputStream(InputStream in,
Deflater defl,
int bufLen)
Creates a new input stream with the specified compressor and buffer
size.
|
| Modifier and Type | Method and Description |
|---|---|
int |
available()
Returns 0 after EOF has been reached, otherwise always return 1.
|
void |
close()
Closes this input stream and its underlying input stream, discarding
any pending uncompressed data.
|
void |
mark(int limit)
This operation is not supported.
|
boolean |
markSupported()
|
int |
read()
Reads a single byte of compressed data from the input stream.
|
int |
read(byte[] b,
int off,
int len)
Reads compressed data into a byte array.
|
void |
reset()
This operation is not supported.
|
long |
skip(long n)
Skips over and discards data from the input stream.
