Properties

access

var access: AccessValues?

The type of access (read/write/readwrite) of this usage.

dependence

var dependence: DependenceType?

The type of dependence (e.g. control or data or none). This field is intentionally nullable, because not all Edge edges are selected in the PDG. This selection is performed in the ProgramDependenceGraphPass.

end

var end: Reference

index

var index: Int?

The index of this node, if it is stored in an de.fraunhofer.aisec.cpg.graph.edges.collections.EdgeList.

labels

open override var labels: Set<String>

name

var name: String?

An optional name.

properties

fun Persistable.properties(): Map<String, Any?>
