copyFromNewInstance

performTreeActions

protected abstract void performTreeActions()

initChildren

protected abstract void initChildren()

navigate

public void navigate(boolean requestFocus)

Description copied from interface: Navigatable

Open editor and select/navigate to the object there if possible. Just do nothing if navigation is not possible like in case of a package

Specified by:

navigate in interface Navigatable

Overrides:

navigate in class AbstractTreeNode<Value>

Parameters:

requestFocus - true if focus requesting is necessary

canNavigate

public boolean canNavigate()

Description copied from interface: Navigatable

Indicates whether this instance supports navigation of any kind. Usually this method is called to ensure that navigation is possible. Note that it is not called if navigation to source is supported, i.e. Navigatable.canNavigateToSource() returns true. We assume that this method should return true in such case, so implement this method respectively.

Specified by:

canNavigate in interface Navigatable

Overrides:

canNavigate in class AbstractTreeNode<Value>

Returns:

false if navigation is not possible for any reason.

canNavigateToSource

public boolean canNavigateToSource()

Description copied from interface: Navigatable

Indicates whether this instance supports navigation to source (that means some kind of editor). Note that navigation can be supported even if this method returns false. In such cases it is not recommended to do batch navigation for all navigatables available via CommonDataKeys.NAVIGATABLE_ARRAY, because it may lead to opening several modal dialogs. Use OpenSourceUtil.navigate(com.intellij.pom.Navigatable...) to process such arrays correctly.

Specified by:

canNavigateToSource in interface Navigatable

Overrides:

canNavigateToSource in class AbstractTreeNode<Value>

Returns:

false if navigation to source is not possible for any reason.

clearChildren

protected void clearChildren()

resetChildren

protected void resetChildren()
