public interface TNode
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 |
---|
TreeExplorer getOwner()
TreeExplorer
where this TNode
is displayed.
javax.swing.tree.TreeNode[] getPath()
TreeNode
s comprising of the ancestors
of this TNode
.
Element getData()
boolean isLeaf()
getAllowsChildren
isLeaf
in interface javax.swing.tree.TreeNode
boolean isRoot()
true
if this TNode
is the root
a tree hierarchy.
ChildFilter getChildFilter()
void setChildFilter(ChildFilter filter, boolean force)
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
.
void setChildFilter(ChildFilter filter)
ChildFilter
on this TNode
. If the
currently set filter is the same as the specified one the method
does nothing.
ChildFilter findChildFilter()
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.
int getChildCount()
TNode
holds.
getChildCount
in interface javax.swing.tree.TreeNode
java.util.Iterator getChildNodes()
Iterator
that can be used to traverse the children
of this TNode
. The items of the Iterator
are Element
s.
java.util.Enumeration getChildTNodes()
Enumeration
that can be used to traverse the children
of this TNode
. The items of the Enumeration
are TNode
s.
java.util.Enumeration breadthFirstEnumeration()
Enumeration
that can be used to traverse all
descendents of this TNode
. The items of the
Enumeration
are TNode
s.
java.util.Comparator getComparator()
Comparator
that is used to sort the children of this
node.
void setComparator(java.util.Comparator comparator)
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.
comparator
- The Comparator
used for sorting the children
of this node; if null
, the children are not sorted.TNode getAncestorTNode(java.lang.Class clazz, boolean checkBaseClass)
TNode
closest ancestor TNode
that
encapsulates an Element
of class clazz
, or if
checkBaseClass
is true
, an Element
extending or implementing the specified class.
Element getAncestor(java.lang.Class clazz, boolean checkBaseClass)
TNode
closest ancestor Element
that
encapsulates an Element
of class clazz
, or if
checkBaseClass
is true
, an Element
extending or implementing the specified class.
Element getAncestor(java.lang.Class clazz)
TNode
closest ancestor Element
that
encapsulates an Element
of class clazz
. This
method only checks for elements whose class is the same as
clazz
.
void setBit(int bit)
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..
void unsetBit(int bit)
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..
boolean isSet(int bit)
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..
