isDataExcluded

protected abstract boolean isDataExcluded()

updateCachedPresentation

protected void updateCachedPresentation()

getText

protected abstract java.lang.String getText(UsageView view)

isValid

public final boolean isValid()

isReadOnly

public final boolean isReadOnly()

isExcluded

public final boolean isExcluded()

updateNotify

protected void updateNotify()

Override to perform node-specific updates
