Constructor Detail

XMLOutlineContentProvider

public XMLOutlineContentProvider()

Constructor for MethodViewContentProvider.

Method Detail

setInput

public void setInput(TreeObject top)

---

getParent

public java.lang.Object getParent(java.lang.Object child)

Description copied from interface: org.eclipse.jface.viewers.ITreeContentProvider

Returns the parent for the given element, or null indicating that the parent can't be computed. In this case the tree-structured viewer can't expand a given node correctly if requested.

Specified by:

getParent in interface org.eclipse.jface.viewers.ITreeContentProvider

---

getChildren

public java.lang.Object[] getChildren(java.lang.Object parent)

Description copied from interface: org.eclipse.jface.viewers.ITreeContentProvider

Returns the child elements of the given parent element.

The difference between this method and IStructuredContentProvider.getElements is that getElements is called to obtain the tree viewer's root elements, whereas getChildren is used to obtain the children of a given parent element in the tree (including a root).

The result is not modified by the viewer.

Specified by:

getChildren in interface org.eclipse.jface.viewers.ITreeContentProvider

---

hasChildren

public boolean hasChildren(java.lang.Object parent)

Description copied from interface: org.eclipse.jface.viewers.ITreeContentProvider

Returns whether the given element has children.

Intended as an optimization for when the viewer does not need the actual children. Clients may be able to implement this more efficiently than getChildren.

Specified by:

hasChildren in interface org.eclipse.jface.viewers.ITreeContentProvider

---

getElements

public java.lang.Object[] getElements(java.lang.Object parent)

Description copied from interface: org.eclipse.jface.viewers.IStructuredContentProvider

Returns the elements to display in the viewer when its input is set to the given element. These elements can be presented as rows in a table, items in a list, etc. The result is not modified by the viewer.

Specified by:

getElements in interface org.eclipse.jface.viewers.IStructuredContentProvider

---

inputChanged

public void inputChanged(org.eclipse.jface.viewers.Viewer v,
                         java.lang.Object oldInput,
                         java.lang.Object newInput)

Description copied from interface: org.eclipse.jface.viewers.IContentProvider

Notifies this content provider that the given viewer's input has been switched to a different element.

A typical use for this method is registering the content provider as a listener to changes on the new input (using model-specific means), and deregistering the viewer from the old input. In response to these change notifications, the content provider should update the viewer (see the add, remove, update and refresh methods on the viewers).

The viewer should not be updated during this call, as it might be in the process of being disposed.

Specified by:

inputChanged in interface org.eclipse.jface.viewers.IContentProvider

---

dispose

public void dispose()

Description copied from interface: org.eclipse.jface.viewers.IContentProvider

Disposes of this content provider. This is called by the viewer when it is disposed.

The viewer should not be updated during this call, as it is in the process of being disposed.

Specified by:

dispose in interface org.eclipse.jface.viewers.IContentProvider

---

getText

public java.lang.String getText(java.lang.Object a)

Description copied from class: org.eclipse.jface.viewers.LabelProvider

The LabelProvider implementation of this ILabelProvider method returns the element's toString string. Subclasses may override.

Specified by:

getText in interface org.eclipse.jface.viewers.ILabelProvider

---

getImage

public org.eclipse.swt.graphics.Image getImage(java.lang.Object a)

Description copied from class: org.eclipse.jface.viewers.LabelProvider

The LabelProvider implementation of this ILabelProvider method returns null. Subclasses may override.

Specified by:

getImage in interface org.eclipse.jface.viewers.ILabelProvider

---

getRoot

public TreeFolder getRoot()

---

getTop

public TreeObject getTop()

---

expandTree

public void expandTree(org.eclipse.jface.viewers.TreeViewer viewer)

---

findElement

public TreeObject findElement(java.lang.Object a)

---

findElement

private TreeObject findElement(java.lang.Object a,
                               TreeObject subtree)

Find object 'a' in the given 'subtree' base on comparison of its encasuplated element.
