Method Detail

nextTwoPow

public static int nextTwoPow(int i)

Returns:

The smallest number which can be written as 2^x which is bigger than i.

read

public void read(byte[] buf,
                 int offset,
                 int len,
                 int skip)

Read data from the buffer.

Parameters:

buf - The buffer where the read data will be copied to.

offset - How many bytes to skip at the beginning of buf.

len - How many bytes to read at all.

skip - How many bytes from our data to skip.

addData

public void addData(byte[] buf,
                    int off,
                    int len)

Add some data to our buffer.

Parameters:

buf - A byte-array to read data from.

off - How many bytes to skip at the beginning of the array.

len - How many bytes to read from the array.

removeData
