所有已实现的接口:

public class RepeatableInputStream
extends InputStream

A repeatable input stream wrapper for any input stream. This input stream relies on buffered data to repeat, and can therefore only be repeated when less data has been read than this buffer can hold.

Note: Always use a RepeatableFileInputStream instead of this class if you are sourcing data from a file, as the file-based repeatable input stream can be repeated without any limitations.

构造器详细资料

RepeatableInputStream

public RepeatableInputStream(InputStream inputStream,
                     int bufferSize)

Creates a repeatable input stream based on another input stream.

参数:

inputStream - The input stream to wrap. The data read from the wrapped input stream is buffered as it is read, up to the buffer limit specified.

bufferSize - The number of bytes buffered by this class.

方法详细资料

reset

public void reset()
           throws IOException

Resets the input stream to the beginning by pointing the buffer offset to the beginning of the available data buffer.

覆盖:

reset 在类中 InputStream

抛出:

IOException - When the available buffer size has been exceeded, in which case the input stream data cannot be repeated.

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 InputStream

另请参阅:

InputStream.markSupported()

mark

public void mark(int readlimit)

This method can only be used while less data has been read from the input stream than fits into the buffer. The readLimit parameter is ignored entirely.

覆盖:

mark 在类中 InputStream

available

public int available()
              throws IOException

覆盖:

available 在类中 InputStream

抛出:

IOException

另请参阅:

InputStream.available()

close

public void close()
           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 InputStream

抛出:

IOException

另请参阅:

InputStream.close()

read

public int read(byte[] out,
       int outOffset,
       int outLength)
         throws IOException

覆盖:

read 在类中 InputStream

抛出:

IOException

另请参阅:

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

read

public int read()
         throws IOException

指定者:

read 在类中 InputStream

抛出:

IOException
