InflaterInputStream (jretty-util 1.5.0 API)

java.lang.Object
- java.io.InputStream
- - java.io.FilterInputStream
  - - org.jretty.util.zip.InflaterInputStream

所有已实现的接口:

Closeable, AutoCloseable

直接已知子类:

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.

    Creates a new input stream with the specified decompressor and buffer size.
    
    参数:
    
    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.
    
    参数:
    
    in - the input stream
    
    inf - the decompressor ("inflater")
  - InflaterInputStream
```

```
    Creates a new input stream with a default decompressor and buffer size.
    
    参数:
    
    in - the input stream

  - read
```
public int read()
         throws IOException
```
    Reads a byte of uncompressed data. This method will block until enough input is available for decompression.
    
    覆盖:
    
    read 在类中 FilterInputStream
    
    返回:
    
    the byte read, or -1 if end of compressed input is reached
    
    抛出:
    
    IOException - if an I/O error has occurred
  - 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.
    
    覆盖:
    
    read 在类中 FilterInputStream
    
    参数:
    
    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
    
    返回:
    
    the actual number of bytes read, or -1 if the end of the compressed input is reached or a preset dictionary is needed
    
    抛出:
    
    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
  - 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.
    
    覆盖:
    
    available 在类中 FilterInputStream
    
    返回:
    
    1 before EOF and 0 after EOF.
    
    抛出:
    
    IOException - if an I/O error occurs.
  - skip
```
public long skip(long n)
          throws IOException
```
    Skips specified number of bytes of uncompressed data.
    
    覆盖:
    
    skip 在类中 FilterInputStream
    
    参数:
    
    n - the number of bytes to skip
    
    返回:
    
    the actual number of bytes skipped.
    
    抛出:
    
    IOException - if an I/O error has occurred
    
    IllegalArgumentException - if n < 0
  - close
```
public void close()
           throws IOException
```
    Closes this input stream and releases any system resources associated with the stream.
    
    指定者:
    
    close 在接口中 Closeable
    
    指定者:
    
    close 在接口中 AutoCloseable
    
    覆盖:
    
    close 在类中 FilterInputStream
    
    抛出:
    
    IOException - if an I/O error has occurred
  - fill
```
protected void fill()
             throws IOException
```
    Fills input buffer with more data to decompress.
    
    抛出:
    
    IOException - if an I/O error has occurred
  - markSupported
```
public boolean markSupported()
```
    Tests if this input stream supports the mark and reset methods. The markSupported method of InflaterInputStream returns false.
    
    覆盖:
    
    markSupported 在类中 FilterInputStream
    
    返回:
    
    a boolean indicating if this stream type supports the mark and reset methods.

    InputStream.mark(int), InputStream.reset()
  - mark
```
public void mark(int readlimit)
```
    Marks the current position in this input stream.
    The mark method of InflaterInputStream does nothing.
    
    覆盖:
    
    mark 在类中 FilterInputStream
    
    参数:
    
    readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.

    InputStream.reset()
  - 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.
    
    覆盖:
    
    reset 在类中 FilterInputStream
    
    抛出:
    
    IOException - if this method is invoked.
