Scope Manager
The scope manager builds a multi-tree structure of nodes associated to a scope. These scopes capture the validity of certain (Variable-, Field-, Record-)declarations but are also used to identify outer scopes that should be the target of a jump (continue, break, throw).
Language frontends MUST call enterScope and leaveScope when they encounter nodes that modify the scope and resetToGlobal when they first handle a new TranslationUnitDeclaration. Afterwards the currently valid "stack" of scopes within the tree can be accessed.
If a language frontend encounters a Declaration node, it MUST call addDeclaration, rather than adding the declaration to the node itself. This ensures that all declarations are properly registered in the scope map and can be resolved later.
Constructors
Types
Functions
This function SHOULD only be used by the de.fraunhofer.aisec.cpg.passes.EvaluationOrderGraphPass while building up the EOG. It adds a BreakStatement to the list of break statements of the current "breakable" scope.
This function SHOULD only be used by the de.fraunhofer.aisec.cpg.passes.EvaluationOrderGraphPass while building up the EOG. It adds a ContinueStatement to the list of continue statements of the current "continuable" scope.
This function MUST be called when a language frontend first handles a Declaration. It adds a declaration to the scope manager, taking into account the currently active scope. Furthermore, it adds the declaration to the de.fraunhofer.aisec.cpg.graph.DeclarationHolder that is associated with the current scope through ValueDeclarationScope.addValueDeclaration and StructureDeclarationScope.addStructureDeclaration.
This function SHOULD only be used by the de.fraunhofer.aisec.cpg.passes.EvaluationOrderGraphPass while building up the EOG. It adds a LabelStatement to the list of label statements of the current scope.
Only used by the de.fraunhofer.aisec.cpg.graph.TypeManager, adds typedefs to the current ValueDeclarationScope.
This function, in combination with leaveScope is the main interaction point with the scope manager for language frontends. Every time a language frontend handles a node that begins a new scope, this function needs to be called. Appropriate scopes will then be created on-the-fly, if they do not exist.
Similar to enterScope, but does so in a "read-only" mode, e.g. it does not modify the scope tree and does not create new scopes on the fly, as enterScope does.
Tries to find the first scope that is an instance of the scope type T. Calls firstScopeOrNull internally.
This function tries to find the first scope that satisfies the condition specified in predicate. It starts searching in the searchScope, moving up-wards using the Scope.parent attribute.
Retrieves the RecordDeclaration for the given name in the given scope.
The counter-part of enterScope. Language frontends need to call this function, when the scope of the currently processed AST node ends. There MUST have been a corresponding enterScope call with the same nodeToLeave, otherwise the scope-tree might be corrupted.
Combines the state of several scope managers into this one. Primarily used in combination with concurrent frontends.
This function MUST be called when a language frontend first enters a translation unit. It sets the GlobalScope to the current translation unit specified in declaration.
Tries to resolve a function in a call expression.
Resolves function templates of the given CallExpression.
Resolves only references to Values in the current scope, static references to other visible records are not resolved over the ScopeManager.
