| PDFTreeModel | | public PDFTreeModel()(Code) | | constructor.
|
| PDFTreeModel | | public PDFTreeModel(PDDocument doc)(Code) | | Constructor to take a document.
Parameters:
doc - The document to display in the tree. |
| getChild | | public Object getChild(Object parent, int index)(Code) | | Returns the child of parent at index index
in the parent's
child array. parent must be a node previously obtained
from this data source. This should not return null
if index
is a valid index for parent (that is index >= 0 &&
index < getChildCount(parent)).
Parameters:
parent - a node in the tree, obtained from this data source
Parameters:
index - The index into the parent object to location the child object. the child of parent at index index |
| getChildCount | | public int getChildCount(Object parent)(Code) | | Returns the number of children of parent.
Returns 0 if the node
is a leaf or if it has no children. parent must be a node
previously obtained from this data source.
Parameters:
parent - a node in the tree, obtained from this data source the number of children of the node parent |
| getIndexOfChild | | public int getIndexOfChild(Object parent, Object child)(Code) | | Returns the index of child in parent. If parent
is null or child is null,
returns -1.
Parameters:
parent - a note in the tree, obtained from this data source
Parameters:
child - the node we are interested in the index of the child in the parent, or -1 if eitherchild or parent are null |
| getRoot | | public Object getRoot()(Code) | | Returns the root of the tree. Returns null
only if the tree has no nodes.
the root of the tree |
| isLeaf | | public boolean isLeaf(Object node)(Code) | | Returns true if node is a leaf.
It is possible for this method to return false
even if node has no children.
A directory in a filesystem, for example,
may contain no files; the node representing
the directory is not a leaf, but it also has no children.
Parameters:
node - a node in the tree, obtained from this data source true if node is a leaf |
| setDocument | | public void setDocument(PDDocument doc)(Code) | | Set the document to display in the tree.
Parameters:
doc - The document to display in the tree. |
| valueForPathChanged | | public void valueForPathChanged(TreePath path, Object newValue)(Code) | | Messaged when the user has altered the value for the item identified
by path to newValue.
If newValue signifies a truly new value
the model should post a treeNodesChanged event.
Parameters:
path - path to the node that the user has altered
Parameters:
newValue - the new value from the TreeCellEditor |
