52  Synopsis    [Tree representing a CTL formula.]
53
54  Description [Data structure for a CTL formula.  A formula is a tree
55  or a one-rooted DAG.  An internal vertex has one or two children,
56  depending on the operator type: if the operator takes just one
57  argument, then the left child holds the subformula, and the right
58  child is NULL; if the operator takes two arguments, then both
59  children are non-NULL.
60 
61  <p>A leaf is either a pair of a variable name in the network and a
62  value, TRUE or FALSE.  The left and right fields are used in leaf
63  vertices only in the first case above. (The left child holds a
64  variable name while the right child holds a value. Note that these
65  two fields are used differently in internal vertices and leaves.)
66
67  <p>DbgInfo is an uninterpreted pointer used by the CTL debugger to store
68  information needed to debug a formula.
69
70  <p>States holds the exact satisfying set of a formula in some fsm (the fsm is
71  not stored along with the set).  The Underapprox and overapprox fields are
72  approximations of the states field. Either states is NIL (no exact result is
73  known), or both underapprox and overapprox are NIL (the exact result is
74  known, or nothing is known at all).
75
76  Note that the convertedFlag being NIL does not imply that originalFormula is
77  NIL: a conversion could have been done that was trivial for the particular
78  node.]
