构造器详细资料

ByteArraySeekableStream

public ByteArraySeekableStream(byte[] buf)

方法详细资料

seek

public void seek(long desired)
          throws IOException

从类复制的说明: SeekableInputStream

Seek to the given offset from the start of the file. The next read() will be from that location. Can't seek past the end of the stream.

指定者:

seek 在类中 SeekableInputStream

参数:

desired - the desired offset

抛出:

IOException - Thrown if an error occurred while seeking inside the input stream.

getPos

public long getPos()
            throws IOException

从类复制的说明: SeekableInputStream

Gets the current position in the input stream.

指定者:

getPos 在类中 SeekableInputStream

返回:

current position in the input stream

抛出:

IOException - Thrown if an I/O error occurred in the underlying stream implementation while accessing the stream's position.

read

public int read()
         throws IOException

指定者:

read 在类中 InputStream

抛出:

IOException

read

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

从类复制的说明: SeekableInputStream

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

指定者:

read 在类中 SeekableInputStream

抛出:

IOException

read

public int read(byte[] b)
         throws IOException

覆盖:

read 在类中 InputStream

抛出:

IOException

skip

public long skip(long n)
          throws IOException

覆盖:

skip 在类中 InputStream

抛出:

IOException

available

public int available()
              throws IOException

覆盖:

available 在类中 InputStream

抛出:

IOException

mark

public void mark(int readlimit)

覆盖:

mark 在类中 InputStream

reset

public void reset()
           throws IOException

覆盖:

reset 在类中 InputStream

抛出:

IOException

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 InputStream

close

public void close()
           throws IOException

从类复制的说明: SeekableInputStream

Closes this input stream and releases any system resources associated with the stream.

The close method of InputStream does nothing.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

指定者:

close 在类中 SeekableInputStream

抛出:

IOException - if an I/O error occurs.
