方法详细资料

available

public int available()
              throws IOException

Returns the number of bytes not yet consumed. Note that this method doen't care about the exact number of bytes that may or may not be available in the underlying InputStream

覆盖:

available 在类中 FilterInputStream

返回:

the number of bytes available.

抛出:

IOException

另请参阅:

FilterInputStream.available()

close

public void close()
           throws IOException

Closes this stream and throws away any bytes not consumed from the underlying InputStream.

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

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 up to the number of bytes defined in this ConfinedInputStream limit.

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

另请参阅:

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

resetLimit

public int resetLimit(int len)

Resets this ConfinedInputStream limit so that it can be reused over the same underlying InputStream.

参数:

len - the new length to set.

返回:

the number of bytes not consumed before reseting the limit.

dumpLeftovers

protected long dumpLeftovers()
                      throws IOException

Skips the number bytes not yet consumed from the underlying InputStream.

返回:

the number of bytes skipped.

抛出:

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