|
Entry point for vspot::ltl::const_visitor instances.
Implements spot::ltl::formula. |
|
Entry point for vspot::ltl::visitor instances.
Implements spot::ltl::formula. |
|
Return a canonic representation of the formula.
|
|
List all instances of atomic propositions. For debugging.
|
|
Get the environment of the atomic proposition.
|
|
Return a hash_key for the formula.
|
|
Build an atomic proposition with name name in environment env. |
|
Number of instantiated atomic propositions. For debugging.
|
|
Get the name of the atomic proposition.
|
|
clone this node This increments the reference counter of this node (if one is used). You should almost never use this method directly as it doesn't touch the children. If you want to clone a whole formula, use spot::ltl::clone() instead. |
|
increment reference counter if any
Reimplemented from spot::ltl::formula. |
|
Number of references to this formula.
|
|
Compute key_ from dump_. Should be called once in each object, after dump_ has been set. |
|
release this node This decrements the reference counter of this node (if one is used) and can free the object. You should almost never use this method directly as it doesn't touch the children. If you want to release a whole formula, use spot::ltl::destroy() instead. |
|
decrement reference counter if any, return true when the instance must be deleted (usually when the counter hits 0).
Reimplemented from spot::ltl::formula. |
|
The canonic representation of the formula.
|
|
|
|
The hash key of this formula. Initialized by set_key_(). |
