Method Detail

createRoot

protected AbstractTreeNode createRoot(Project project,
                                      ViewSettings settings)

getRootElement

public final java.lang.Object getRootElement()

Specified by:

getRootElement in class AbstractTreeStructure

commit

public final void commit()

Specified by:

commit in class AbstractTreeStructure

asyncCommit

public ActionCallback asyncCommit()

Overrides:

asyncCommit in class AbstractTreeStructure

Returns:

callback which is set to ActionCallback.setDone() when the tree structure is committed. By default it just calls AbstractTreeStructure.commit() synchronously but it is desirable to override it to provide asynchronous commit to the tree structure to make it more responsible. E.g. when you should commit all documents during the AbstractTreeStructure.commit(), you can use AbstractTreeStructure.asyncCommitDocuments(Project) to do it asynchronously.

hasSomethingToCommit

public final boolean hasSomethingToCommit()

Specified by:

hasSomethingToCommit in class AbstractTreeStructure

isAlwaysLeaf

public boolean isAlwaysLeaf(java.lang.Object element)

Overrides:

isAlwaysLeaf in class AbstractTreeStructure
