构造器详细资料

BaseNCodecInputStream

protected BaseNCodecInputStream(InputStream in,
                                BaseNCodec baseNCodec,
                                boolean doEncode)

方法详细资料

available

public int available()
              throws IOException

覆盖:

available 在类中 FilterInputStream

返回:

0 if the InputStream has reached EOF, 1 otherwise

抛出:

IOException

从以下版本开始:

1.7

mark

public void mark(int readLimit)

Marks the current position in this input stream.

The mark(int) method of BaseNCodecInputStream 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.

从以下版本开始:

1.7

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 FilterInputStream

返回:

always returns false

read

public int read()
         throws IOException

Reads one byte from this input stream.

覆盖:

read 在类中 FilterInputStream

返回:

the byte as an integer in the range 0 to 255. Returns -1 if EOF has been reached.

抛出:

IOException - if an I/O error occurs.

read

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

Attempts to read len bytes into the specified b array starting at offset from this InputStream.

覆盖:

read 在类中 FilterInputStream

参数:

b - destination byte array

offset - where to start writing the bytes

len - maximum number of bytes to read

返回:

number of bytes read

抛出:

IOException - if an I/O error occurs.

NullPointerException - if the byte array parameter is null

IndexOutOfBoundsException - if offset, len or buffer size are invalid

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 reset() method of BaseNCodecInputStream does nothing except throw an IOException.

覆盖:

reset 在类中 FilterInputStream

抛出:

IOException - if this method is invoked

从以下版本开始:

1.7

skip

public long skip(long n)
          throws IOException

覆盖:

skip 在类中 FilterInputStream

抛出:

IllegalArgumentException - if the provided skip length is negative

IOException

从以下版本开始:

1.7
