Predicates

getAChild	Gets a child of this node, which can also be retrieved using a predicate named `pred`.
getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this node belongs.
getValue	Gets the expression resulting in the object on which the singleton class is defined. In the following example, the result is the `Expr` for `foo`:
toString	Gets a textual representation of this node.

getNamespaceOrToplevel	Gets the nearest enclosing `Namespace` or `Toplevel`, possibly this module itself.	from ModuleBase
getNumberOfStatements	Gets the number of statements in this sequence.	from StmtSequence
getOuterScope	Gets the outer scope, if any.	from Scope
getParent	Gets the parent of this `AstNode`, if this node is not a root node.	from AstNode
