Detailed Description

A read only environment.

This environment decorate another environment, and allow only atomic propositions that have been declared therein.

bool spot::ltl::read_only_environment::declare ( const std::string & prop_str )

Declare an atomic proposition. Return false iff the proposition was already declared.

virtual ltl::formula* spot::ltl::read_only_environment::require ( const std::string & prop_str ) [virtual]

Obtain the formula associated to prop_str.

Usually prop_str, is the name of an atomic proposition, and spot::ltl::require simply returns the associated spot::ltl::atomic_prop.

Note this is not a const method. Some environments will "create" the atomic proposition when requested.

We return a spot::ltl::formula instead of an spot::ltl::atomic_prop, because this will allow nifty tricks (e.g., we could name formulae in an environment, and let the parser build a larger tree from these).
