Detailed Description

An environment that describes atomic propositions.

Member Function Documentation

name()

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

pure virtual

Get the name of the environment.

Implemented in spot::declarative_environment, and spot::default_environment.

require()

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

pure virtual

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.

Implemented in spot::declarative_environment, and spot::default_environment.
