Examples of org.eclipse.jface.text.Position.overlapsWith()

org.eclipse.jface.text.Position.overlapsWith()
Checks whether the intersection of the given text range and the text range represented by this position is empty or not. @param rangeOffset the offset of the range to check @param rangeLength the length of the range to check @return true if intersection is not empty
