Constructors

constructor

new CallGraph(nodeMap, astIdToNodeId, nameToNodeId, edgesMap): CallGraph
Parameters
- nodeMap: Map<CGNodeId, CGNode>
- astIdToNodeId: Map<number, CGNodeId>
- nameToNodeId: Map<string, CGNodeId>
- edgesMap: Map<CGEdgeId, CGEdge>
Returns CallGraph
- Defined in src/internals/ir/callGraph.ts:163

Methods

areConnected

areConnected(src, dst): boolean
Determines if there exists a path from the source node to the destination node. This is achieved via a breadth-first search.
Parameters
- src: CGNodeId
  The ID of the source node.
- dst: CGNodeId
  The ID of the destination node.
Returns boolean
true if a path exists; false otherwise.
- Defined in src/internals/ir/callGraph.ts:221

getEdges

getEdges(): Map<CGEdgeId, CGEdge>
Retrieves all edges in the call graph.

Returns Map<CGEdgeId, CGEdge>
A map of all edges by their unique IDs.
- Defined in src/internals/ir/callGraph.ts:182

getNode

getNode(nodeId): undefined | CGNode
Retrieves a node by its ID.
Parameters
- nodeId: CGNodeId
  The unique ID of the node.
Returns undefined | CGNode
The corresponding node, or undefined if not found.
- Defined in src/internals/ir/callGraph.ts:209

getNodeIdByAstId

getNodeIdByAstId(astId): undefined | CGNodeId
Retrieves a node's ID by the AST ID of its definition.
Parameters
- astId: number
  The AST ID of the function definition.
Returns undefined | CGNodeId
The corresponding node ID, or undefined if not found.
- Defined in src/internals/ir/callGraph.ts:200

getNodeIdByName

getNodeIdByName(name): undefined | CGNodeId
Retrieves a node's ID by its name.
Parameters
- name: string
  The name of the function or method.
Returns undefined | CGNodeId
The corresponding node ID, or undefined if not found.
- Defined in src/internals/ir/callGraph.ts:191

getNodes

getNodes(): Map<CGNodeId, CGNode>
Retrieves all nodes in the call graph.

Returns Map<CGNodeId, CGNode>
A map of all nodes by their unique IDs.
- Defined in src/internals/ir/callGraph.ts:174

`Static`getFunctionCallName

getFunctionCallName(expr, currentContractName?): undefined | string
Derives the function call name from a static or method call expression.
Parameters
- expr: AstMethodCall | AstStaticCall
  The call expression.
- OptionalcurrentContractName: string
  The name of the current contract, if available.
Returns undefined | string
The fully qualified function name, or undefined if it is irrelevant.
- Defined in src/internals/ir/callGraph.ts:254
