- Method Detail
  - offset
```
int offset()
```
    returns the current offset in the buffer
    
    Returns:
    
    the offset
  - readBitMap
```
BitMap4 readBitMap(int bitCount)
```
  - readByte
```
byte readByte()
```
    reads a byte from the buffer.
    
    Returns:
    
    the byte
  - readBytes
```
void readBytes(byte[] bytes)
```
    reads an array of bytes from the buffer. The length of the array that is passed as a parameter specifies the number of bytes that are to be read. The passed bytes buffer parameter is directly filled.
    
    Parameters:
    
    bytes - the byte array to read the bytes into.
  - readInt
```
int readInt()
```
    reads an int from the buffer.
    
    Returns:
    
    the int
  - readLong
```
long readLong()
```
    reads a long from the buffer.
    
    Returns:
    
    the long
  - seek
```
void seek(int offset)
```
    positions the read pointer at the specified position
    
    Parameters:
    
    offset - the desired position in the buffer
