This environment recognizes all atomic propositions.

This is a singleton. Use default_environment::instance() to obtain the instance.

Member Function Documentation

instance()

static default_environment& spot::default_environment::instance ( )

static

Get the sole instance of spot::default_environment.

name()

virtual const std::string& spot::default_environment::name ( ) const

overridevirtual

Get the name of the environment.

Implements spot::environment.

require()

virtual formula spot::default_environment::require ( const std::string &  prop_str )

overridevirtual

Obtain the formula associated to prop_str.

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

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

Returns

0 iff prop_str is not part of the environment, or the associated spot::formula otherwise.

Implements spot::environment.
