TNode (Oracle Fusion Middleware Java API Reference for Oracle Extension SDK)

All Superinterfaces:

javax.swing.tree.TreeNode
```
public interface TNode
extends javax.swing.tree.TreeNode
```
The TNode interface extends the TreeNode. This class encapsulates an Element and its main purpose is to represent that Element as a tree node.

- Method Detail
  - getOwner
```
TreeExplorer getOwner()
```
    Returns the TreeExplorer where this TNode is displayed.
  - getPath
```
javax.swing.tree.TreeNode[] getPath()
```
    Returns an array of TreeNodes comprising of the ancestors of this TNode.
  - getData
```
Element getData()
```
    Gets the data element associated with this node.
    
    Returns:
    
    the data element associated with this node.
  - isLeaf
```
boolean isLeaf()
```
    Returns true if this TNode has no children. To distinguish between nodes that have no children and nodes that cannot have children (e.g. to distinguish files from empty directories), use this method in conjunction with getAllowsChildren
    
    Specified by:
    
    isLeaf in interface javax.swing.tree.TreeNode
    
    Returns:
    
    true if this node cannot have children
  - isRoot
```
boolean isRoot()
```
    Returns true if this TNode is the root a tree hierarchy.
  - getChildFilter
```
ChildFilter getChildFilter()
```
    Returns the active ChildFilter. If first checks if the owner has already been set. If it is it looks up the filter in the filter cache.
  - setChildFilter
```
void setChildFilter(ChildFilter filter,
                    boolean force)
```
    Set a new ChildFilter on this TNode. If the currently set filter is the same as the specified one the method does nothing unless the parameter force is set to true.
  - setChildFilter
```
void setChildFilter(ChildFilter filter)
```
    Set a new ChildFilter on this TNode. If the currently set filter is the same as the specified one the method does nothing.
  - findChildFilter
```
ChildFilter findChildFilter()
```
    Find the ChildFilter used to build the tree node hierarchy this TNode belongs to. This method walks up the ancestor hierarchy until it finds a filter. If no filter is found, null is returned.
  - getChildCount
```
int getChildCount()
```
    Returns the number of children this TNode holds.
    
    Specified by:
    
    getChildCount in interface javax.swing.tree.TreeNode
  - getChildNodes
```
java.util.Iterator getChildNodes()
```
    Returns an Iterator that can be used to traverse the children of this TNode. The items of the Iterator are Elements.
  - getChildTNodes
```
java.util.Enumeration getChildTNodes()
```
    Returns an Enumeration that can be used to traverse the children of this TNode. The items of the Enumeration are TNodes.
  - breadthFirstEnumeration
```
java.util.Enumeration breadthFirstEnumeration()
```
    Returns an Enumeration that can be used to traverse all descendents of this TNode. The items of the Enumeration are TNodes.
  - getComparator
```
java.util.Comparator getComparator()
```
    Get the Comparator that is used to sort the children of this node.
  - setComparator
```
void setComparator(java.util.Comparator comparator)
```
    Set the Comparator that is used to sort the children of this node. Calling this method has no effect if the node is not a container node. If the comparator has changed, then the child nodes are re-ordered.
    
    Parameters:
    
    comparator - The Comparator used for sorting the children of this node; if null, the children are not sorted.
  - getAncestorTNode
```
TNode getAncestorTNode(java.lang.Class clazz,
                       boolean checkBaseClass)
```
    Gets this TNode closest ancestor TNode that encapsulates an Element of class clazz, or if checkBaseClass is true, an Element extending or implementing the specified class.
  - getAncestor
```
Element getAncestor(java.lang.Class clazz,
                    boolean checkBaseClass)
```
    Gets this TNode closest ancestor Element that encapsulates an Element of class clazz, or if checkBaseClass is true, an Element extending or implementing the specified class.
  - getAncestor
```
Element getAncestor(java.lang.Class clazz)
```
    Gets this TNode closest ancestor Element that encapsulates an Element of class clazz. This method only checks for elements whose class is the same as clazz.
  - setBit
```
void setBit(int bit)
```
    Sets the specified bit attribute. Attributes generally indicate the state of the TNode, such as if the node has been opened (IS_OPENED), is using a filter (IS_UNFILTERED), etc..
  - unsetBit
```
void unsetBit(int bit)
```
    Unsets the specified bit attribute. Attributes generally indicate the state of the TNode, such as if the node has been opened (IS_OPENED), is using a filter (IS_UNFILTERED), etc..
  - isSet
```
boolean isSet(int bit)
```
    Check if the specified bit attribute is set. Attributes generally indicate the state of the TNode, such as if the node has been opened (IS_OPENED), is using a filter (IS_UNFILTERED), etc..
