Predicates

callStep	Holds if `nodeFrom` steps to `nodeTo` by being passed as a parameter in a call.
compatibleContents	Holds if a value stored with `storeContents` can be read back with `loadContents`.
hasFeatureBacktrackStoreTarget	Holds if the target of store steps should be backtracked via `simpleLocalSmallStep` to a `LocalSourceNode`. If this flag is not set, then the targets of store steps are assumed to be `LocalSourceNode`s themselves.
jumpStep	Holds if data can flow from `node1` to `node2` in a way that discards call contexts.
levelStepCall	Holds if there is a level step from `nodeFrom` to `nodeTo`, which may depend on the call graph.
levelStepNoCall	Holds if there is a level step from `nodeFrom` to `nodeTo`, which does not depend on the call graph.
loadStep	Holds if `nodeTo` is the result of accessing the `content` content of `nodeFrom`.
loadStoreStep	Holds if the `loadContent` of `nodeFrom` is stored in the `storeContent` of `nodeTo`.
nonStandardFlowsTo	Holds if a non-standard `flowsTo` predicate is needed, i.e., one that is not simply `simpleLocalSmallStep*(localSource, dst)`.
returnStep	Holds if `nodeFrom` steps to `nodeTo` by being returned from a call.
simpleLocalSmallStep	Holds if there is a simple local flow step from `nodeFrom` to `nodeTo`
storeStep	Holds if `nodeFrom` is being written to the `content` content of the object in `nodeTo`.
withContentStep	Holds if type-tracking should step from `nodeFrom` to `nodeTo` if inside a content matched by `filter`.
withoutContentStep	Holds if type-tracking should step from `nodeFrom` to `nodeTo` but block flow of contents matched by `filter` through here.

Classes

Content	A type of content to be used with the store and read steps.
ContentFilter	A label to use for `WithContent` and `WithoutContent` steps, restricting which `ContentSet` may pass through.

Aliases

LocalSourceNode	A data flow node that is a source of local flow. This includes things like - Expressions - Function parameters
Node	An element, viewed as a node in a data flow graph. Either an SSA variable (`EssaNode`) or a control flow node (`CfgNode`).
