Which UML diagram? Class or state or ?

There are a *lot* of straight and dotted lined arrows in UML, so it's a bit
difficult to answer it in short, e.g. with full triangle heads, the straight
lines mean "inheritance" (extends), while the dotted ones mean
"implementation" (implements).

------------------------------------------------

Otherwise in a static chart diagram the straight lined arrow can mean
"uni-directional association", while the dotted line means "dependency". A
small example:

class A {}

class B
{
  // uni-directional association
  A a;
}

class C
{
  // dependency, but no association
  void method(A a) {...}
}

C ----> A (dotted line)
B ----> A (but with a straight line)

-----------------------------------------------

In a sequence diagram, the straight lined arrow means a message (method
call), while the dotted arrow is where the method returns to the caller.
