public abstract class JSMaterializedInvokeTargetableNode extends JSTargetableNode
MaterializedInvokeNode to report JS function values to
the instrumentation framework.
By default, InvokeNode evaluates its target node in two separate steps: first, the
node is evaluated to retrieve the target value. Then, the same node is evaluated via
executeWithTarget() to retrieve the JS function instance to be called. The second
evaluation via executeWithTarget() causes a read event (e.g., property read) that
will be detected by the instrumentation framework. Since the target is already evaluated, such
read event will however miss its target value, resulting in a wrong series of
instrumentation events.
The materialized nodes in this class internally re-evaluate the target value
provided via executeWithTarget() using the internal EchoTargetValueNode
. In this way, the instrumentation framework is able to trace target and report it
correctly as an onInput value.| Modifier and Type | Class and Description |
