Method Detail

mark

public void mark(int readlimit)

Overrides:

mark in class java.io.FilterInputStream

read

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

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

read

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

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

read

public int read()
         throws java.io.IOException

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

reset

public void reset()
           throws java.io.IOException

Overrides:

reset in class java.io.FilterInputStream

Throws:

java.io.IOException

skip

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

Overrides:

skip in class java.io.FilterInputStream

Throws:

java.io.IOException

checkThreshold

protected void checkThreshold()
                       throws java.io.IOException

Checks whether reading count bytes would cross the limit.

Throws:

java.io.IOException

getThreshold

public int getThreshold()

Returns:

the current threshold value.

thresholdReached

protected abstract void thresholdReached(int current)
                                  throws java.io.IOException

Called when the threshold is about to be exceeded. This isn't exact; it's called whenever a write would occur that would cross the amount. Once it is called, it isn't called again.

Parameters:

current - is the current number of bytes that have been written

Throws:

java.io.IOException
