Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Element`	`getParent()`	`getParent` returns the parent `Element` if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.
`boolean`	`isReadOnly()`	`isReadOnly` returns true if this node is read only and cannot be modified.
`void`	`setParent(Element parent)`	`setParent` sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.
`void`	`setValue(String value)`	Sets the value of this attribute or this method will throw an `UnsupportedOperationException` if it is read-only.
`boolean`	`supportsParent()`	`supportsParent` returns true if this node supports the parent relationship.

- Method Detail
  - setValue
```
public void setValue(String value)
```
    Description copied from interface: Attribute
    
    Sets the value of this attribute or this method will throw an UnsupportedOperationException if it is read-only.
    
    Specified by:
    
    setValue in interface Attribute
    
    Overrides:
    
    setValue in class AbstractAttribute
    
    Parameters:
    
    value - is the new value of this attribute
  - getParent
```
public Element getParent()
```
    Description copied from interface: Node
    
    getParent returns the parent Element if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.
    
    This method is an optional feature and may not be supported for all Node implementations.
    
    Specified by:
    
    getParent in interface Node
    
    Overrides:
    
    getParent in class AbstractNode
    
    Returns:
    
    the parent of this node or null if it is the root of the tree or the parent relationship is not supported.
  - setParent
```
public void setParent(Element parent)
```
    Description copied from interface: Node
    
    setParent sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.
    
    This method should only be called from inside an Element implementation method and is not intended for general use.
    
    Specified by:
    
    setParent in interface Node
    
    Overrides:
    
    setParent in class AbstractNode
    
    Parameters:
    
    parent - is the new parent of this node.
  - supportsParent
```
public boolean supportsParent()
```
    Description copied from interface: Node
    
    supportsParent returns true if this node supports the parent relationship.
    
    Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.
    
    Specified by:
    
    supportsParent in interface Node
    
    Overrides:
    
    supportsParent in class AbstractNode
    
    Returns:
    
    true if this node supports the parent relationship or false it is not supported
  - isReadOnly
```
public boolean isReadOnly()
```
    Description copied from interface: Node
    
    isReadOnly returns true if this node is read only and cannot be modified. Any attempt to modify a read-only Node will result in an UnsupportedOperationException being thrown.
    
    Specified by:
    
    isReadOnly in interface Node
    
    Overrides:
    
    isReadOnly in class AbstractNode
    
    Returns:
    
    true if this Node is read only and cannot be modified otherwise false.
