What's the boolean parameter passed to the RoiManager constructor?

One of the overloaded constructors of RoiManager class takes a boolean as parameter:

public RoiManager(boolean b)

Unfortunately, the document is silent about this parameter. How can I figure out its meaning?

Hi,

Looking at the source code of RoiManager (ij-1.50e) tells me that the parameter isn’t actually used for anything. But this constructor still behaves differently than the default constructor. To quote the comments (sic):

Constructs an ROIManager without displaying it.
