构造器详细资料

BaseNCodecInputStream

protected BaseNCodecInputStream(java.io.InputStream in,
                     BaseNCodec baseNCodec,
                     boolean doEncode)

方法详细资料

read

public int read()
         throws java.io.IOException

Reads one byte from this input stream.

覆盖:

read 在类中 java.io.FilterInputStream

返回:

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

抛出:

java.io.IOException - if an I/O error occurs.

read

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

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

覆盖:

read 在类中 java.io.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:

java.io.IOException - if an I/O error occurs.

java.lang.NullPointerException - if the byte array parameter is null

java.lang.IndexOutOfBoundsException - if offset, len or buffer size are invalid

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 java.io.FilterInputStream

返回:

false
