ObjectHeapGraphEdge

HeapGraphEdge represents twoHeapGraphNodeAssociations between nodes, from upstream nodes to downstream nodes

inheritance relationship

member properties

type

Integer, link mode of downstream nodes, possible values:

1
readonly Integer HeapGraphEdge.type;

• profiler.Edge_ContextVariable, variables in the function
• profiler.Edge_Element, elements in the array
• profiler.Edge_Property, properties of named objects
• profiler.Edge_Internal, links that cannot be accessed by JS
• profiler.Edge_Hidden, points to the node whose space size needs to be calculated in advance
• profiler.Edge_Shortcut, points to a node whose space size cannot be calculated in advance
• profiler.Edge_Weak, a weak reference (ignored by GC)

---

name

String, link name

1
readonly String HeapGraphEdge.name;

---

description

String, description of the link

1
readonly String HeapGraphEdge.description;

member function

getFromNode

Get the upstream of HeapGraphEdgeHeapGraphNodenode

1
HeapGraphNode HeapGraphEdge.getFromNode();

Return results:

• HeapGraphNode, return to sourceHeapGraphNodenode

---

getToNode

Get the downstream of HeapGraphEdgeHeapGraphNodenode

1
HeapGraphNode HeapGraphEdge.getToNode();

Return results:

• HeapGraphNode, return destinationHeapGraphNodenode

---

toString

Returns the string representation of the object. Generally, "[Native Object]" is returned. The object can be re-implemented according to its own characteristics.

1
String HeapGraphEdge.toString();

Return results:

• String, returns the string representation of the object

---

toJSON

Returns a JSON format representation of the object, generally returning a collection of readable properties defined by the object.

1
Value HeapGraphEdge.toJSON(String key = "");

Call parameters:

• key: String, not used

Return results:

• Value, returns a value containing JSON serializable
