public ByteQueue(int capacity)
Method Detail

nextTwoPow

public static final 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

public void removeData(int i)
Remove some bytes from our data from the beginning.

Parameters:
i - How many bytes to remove.

removeData

public void removeData(byte[] buf,
                       int off,
                       int len,
                       int skip)
Remove data from the buffer.

Parameters:
buf - The buffer where the removed data will be copied to.
off - 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.

removeData

public byte[] removeData(int len,
                         int skip)

size

public int size()
Returns:
The number of bytes which are available in this buffer.
