use of com.ge.research.osate.verdict.dsl.verdict.Exists in project VERDICT by ge-high-assurance.

the class ThreatModelUtil method getScope.

/**
 * Get all variables in scope for an expression.
 *
 * Searches up the AST for variable introductions, starting from the
 * immediate parent of obj.
 *
 * Note that if scoping a quantification, you cannot pass the object
 * directly because this might include the newly-introduced variable
 * in its own scope! See getContainerForClasses() for obtaining the
 * correct parent to use for scoping.
 *
 * @param obj the context for which to find scope.
 * @param indexProvider the index provider, may be obtained from Guice
 * @return the list of variables that are in scope
