Class PostUpdateNode

A node associated with an object after an operation that might have changed its state.

This can be either the argument to a callable after the callable returns (which might have mutated the argument), or the qualifier of a field after an update to the field.

Nodes corresponding to AST elements, for example ExprNode, usually refer to the value before the update with the exception of ClassInstanceExpr, which represents the value after the constructor has run.

Predicates

getFunction	Gets the function to which this node belongs.
getLocation	Gets the location of this element.
getPreUpdateNode	Gets the node before the state update.
getType	Gets the type of this node.

Inherited predicates

asDefiningArgument	Gets the argument that defines this `DefinitionByReferenceNode`, if any. This predicate should be used instead of `asExpr` when referring to the value of a reference argument after the call has returned. For example, in `f(&x)`, this predicate will have `&x` as its result for the `Node` that represents the new value of `x`.	from Node
asExpr	Gets the expression corresponding to this node, if any. This predicate only has a result on nodes that represent the value of evaluating the expression. For data flowing out of an expression, like when an argument is passed by reference, use `asDefiningArgument` instead of `asExpr`.	from Node
asParameter	Gets the parameter corresponding to this node, if any.	from Node
asPartialDefinition	Gets the expression that is partially defined by this node, if any.	from Node
asUninitialized	Gets the uninitialized local variable corresponding to this node, if any.	from Node
getEnclosingCallable	INTERNAL: Do not use. Alternative name for `getFunction`.	from Node
getTypeBound	Gets an upper bound on the type of this node.	from Node
toString	Gets a textual representation of this element.	from Node
