  - clone
```
public Object clone()
```
    Description copied from class: Object
    
    Creates and returns a copy of this Object. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.
    
    Overrides:
    
    clone in class Object
    
    Returns:
    
    a copy of this object.
  - hashCode
```
public int hashCode()
```
    Returns the hash code of this Attributes.
    
    Specified by:
    
    hashCode in interface Map<Object,Object>
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code of this object.
    
    See Also:
    
    Object.equals(java.lang.Object)
  - equals
```
public boolean equals(Object obj)
```
    Determines if this Attributes and the parameter Attributes are equal. Two Attributes instances are equal if they contain the same keys and values.
    
    Specified by:
    
    equals in interface Map<Object,Object>
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object with which this Attributes is compared.
    
    Returns:
    
    true if the Attributes are equal, false otherwise.
    
    See Also:
    
    Object.hashCode()
  - getValue
```
public String getValue(Attributes.Name name)
```
    Returns the value associated with the parameter Attributes.Name key.
    
    Parameters:
    
    name - the key to obtain the value for.
    
    Returns:
    
    the String associated with name, or null if name is not a valid key.
  - getValue
```
public String getValue(String name)
```
    Returns the string associated with the parameter name.
    
    Parameters:
    
    name - the key to obtain the value for.
    
    Returns:
    
    the string associated with name, or null if name is not a valid key.
  - putValue
```
public String putValue(String name,
                       String value)
```
    Stores the value value associated with the key name in this Attributes.
