    Description copied from interface: Attributes
    
    Sets an attribute. In case value = null attribute is removed from the attributes map. Attribute names starting with _ indicate system attributes.
    
    Specified by:
    
    setAttribute in interface Attributes
    
    Parameters:
    name - attribute name
    value - attribute value
  - getAttribute
```
public byte[] getAttribute(String name)
```
    Description copied from interface: Attributes
    
    Gets an attribute
    
    Specified by:
    
    getAttribute in interface Attributes
    
    Parameters:
    name - attribute name
    
    Returns:
    attribute value if attribute is set, null otherwise
  - getAttributesMap
```
public Map<String,byte[]> getAttributesMap()
```
    Description copied from interface: Attributes
    
    Gets all attributes
    
    Specified by:
    
    getAttributesMap in interface Attributes
    
    Returns:
    unmodifiable map of all attributes
  - getAttributeSize
```
protected long getAttributeSize()
```
  - setId
```
public OperationWithAttributes setId(String id)
```
    This method allows you to set an identifier on an operation. The original motivation for this was to allow the identifier to be used in slow query logging, but this could obviously be useful in other places. One use of this could be to put a class.method identifier in here to see where the slow query is coming from.
    
    Parameters:
    id - id to set for the scan
  - getId
```
public String getId()
```
    This method allows you to retrieve the identifier for the operation if one was set.
    
    Returns:
    the id or null if not set
