Testing if point is inside an object (spacial)

I am new to JMonkey. What is the correct way to test if a point or another object is inside another shape, like a cone for example?  I tried to use hasCollision but this only returns true if the two spatials are intersecting.  It returns false if one object is completely inside the other object.  Is there a way to make this inside of one of the objects solid, so that the collision detection would return true?  Sorry if this is a really easy question and I am missing something in the documentation.
