    Contiguous raw bytes that may start at any index in the containing array. Max length is Integer.MAX_VALUE which is 2,147,483,647 bytes.
    
    Specified by:
    
    getValueArray in interface Cell
    
    Returns:
    
    The array containing the value bytes.

    Specified by:
    
    getValueLength in interface Cell
    
    Returns:
    
    Number of value bytes. Must be < valueArray.length - offset.
  - getSerializedSize

    Specified by:
    
    getSerializedSize in interface Cell
    
    Returns:
    
    Serialized size (defaults to include tag length if has some tags).
  - getTagsArray
```
public byte[] getTagsArray()
```
    Description copied from interface: Cell
    
    Contiguous raw bytes representing tags that may start at any index in the containing array.
    
    Specified by:
    
    getTagsArray in interface Cell
    
    Returns:
    
    the tags byte array
  - getTagsOffset
```
public int getTagsOffset()
```
    Specified by:
    
    getTagsOffset in interface Cell
    
    Returns:
    
    the first offset where the tags start in the Cell
  - getTagsLength
```
public int getTagsLength()
```
    Description copied from interface: Cell
    
    HBase internally uses 2 bytes to store tags length in Cell. As the tags length is always a non-negative number, to make good use of the sign bit, the max of tags length is defined 2 * Short.MAX_VALUE + 1 = 65535. As a result, the return type is int, because a short is not capable of handling that. Please note that even if the return type is int, the max tags length is far less than Integer.MAX_VALUE.
    
    Specified by:
    
    getTagsLength in interface Cell
    
    Returns:
    
    the total length of the tags in the Cell.
  - heapSize
```
public long heapSize()
```
    Specified by:
    
    heapSize in interface HeapSize
    
    Returns:
    
    Approximate 'exclusive deep size' of implementing object. Includes count of payload and hosting object sizings.
