所有已实现的接口:

Closeable, AutoCloseable

public class CompressionSplittedInputStream
extends FilterInputStream

An InputStream wrapper that analyzes X Protocol frames and, if compressed, routes them to a secondary compressor-able InputStream that also knows how to rebuild uncompressed X Protocol frames from compressed ones.

方法详细资料

available

public int available()
              throws IOException

Same as InputStream.available(), except that the exact number of bytes that can be read from the underlying InputStream may not be accurate until it is known if the next bytes contain compressed data or not.

覆盖:

available 在类中 FilterInputStream

返回:

an approximate number of available bytes to read.

抛出:

IOException

另请参阅:

FilterInputStream.available()

close

public void close()
           throws IOException

Closes this stream.

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

覆盖:

close 在类中 FilterInputStream

抛出:

IOException

另请参阅:

FilterInputStream.close()

read

public int read()
         throws IOException

Forwards the read to read(byte[], int, int).

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

另请参阅:

FilterInputStream.read()

read

public int read(byte[] b)
         throws IOException

Forwards the read to read(byte[], int, int).

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

另请参阅:

FilterInputStream.read(byte[])

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Reads bytes from the underlying InputStream either from the one that gets data directly from the original source InputStream or from a compressor able InputStream, if reading of a compressed X Protocol frame is in progress.

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

另请参阅:

FilterInputStream.read(byte[], int, int)

readFully

public int readFully(byte[] b)
              throws IOException

Reads the number of bytes required to fill the given buffer from the underlying InputStream, blocking if needed.

参数:

b - the buffer into which the data is read.

返回:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

抛出:

IOException - if any of the underlying I/O operations fail.
