Constructor Detail

BaseNCodecInputStream

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

Method Detail

available

public int available()
              throws java.io.IOException

Overrides:

available in class java.io.FilterInputStream

Returns:

0 if the InputStream has reached EOF, 1 otherwise

Throws:

java.io.IOException

Since:

1.7

mark

public void mark(int readLimit)

Marks the current position in this input stream.

The mark(int) method of BaseNCodecInputStream does nothing.

Overrides:

mark in class java.io.FilterInputStream

Parameters:

readLimit - the maximum limit of bytes that can be read before the mark position becomes invalid.

Since:

1.7

markSupported

public boolean markSupported()

Overrides:

markSupported in class java.io.FilterInputStream

Returns:

always returns false

read

public int read()
         throws java.io.IOException

Reads one byte from this input stream.

Overrides:

read in class java.io.FilterInputStream

Returns:

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

Throws:

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.

Overrides:

read in class java.io.FilterInputStream

Parameters:

b - destination byte array

offset - where to start writing the bytes

len - maximum number of bytes to read

Returns:

number of bytes read

Throws:

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

reset

public void reset()
           throws java.io.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.

Overrides:

reset in class java.io.FilterInputStream

Throws:

java.io.IOException - if this method is invoked

Since:

1.7

skip

public long skip(long n)
          throws java.io.IOException

Overrides:

skip in class java.io.FilterInputStream

Throws:

java.lang.IllegalArgumentException - if the provided skip length is negative

java.io.IOException

Since:
