|
|
Get the sole operand of this operator.
|
|
Build an unary operator with operation op and child child. |
|
Number of instantiated unary operators. For debugging.
|
|
Get the type of this operator.
|
|
Get the type of this operator, as a string.
|
|
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. |
|
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. |
