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.

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.

available

public int available()

Returns:

The number of bytes which are available in this buffer.

copyTo

public void copyTo(java.io.OutputStream output,
                   int length)
            throws java.io.IOException

Copy some bytes from the beginning of the data to the provided OutputStream.

Parameters:

output - The OutputStream to copy the bytes to.

length - How many bytes to copy.

Throws:

java.io.IOException

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.

readFrom

public java.io.ByteArrayInputStream readFrom(int length)

Return a ByteArrayInputStream over some bytes at the beginning of the data.

Parameters:

length - How many bytes will be readable.

Returns:

A ByteArrayInputStream over the data.

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)

shrink
