Object HeapGraphEdge

HeapGraphEdge represents the association between two HeapGraphNode nodes, from upstream nodes to downstream nodes

Inheritance

Member attribute

type

Integer, the link mode of the downstream node, possible values:

1
readonly Integer HeapGraphEdge.type;

• profiler.Edge_ContextVariable , variable in function
• profiler.Edge_Element , the element in the array
• profiler.Edge_Property , the property of a named object
• profiler.Edge_Internal , a link that JS cannot enter
• profiler.Edge_Hidden , points to the node that needs to calculate the size of the space 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 HeapGraphNode node of HeapGraphNode

1
HeapGraphNode HeapGraphEdge.getFromNode();

Return result:

• HeapGraphNode , returns the source HeapGraphNode node

getToNode

Get the downstream HeapGraphNode node of HeapGraphNode

1
HeapGraphNode HeapGraphEdge.getToNode();

Return result:

• HeapGraphNode , returns the destination HeapGraphNode node

toString

Returns the string representation of the object, generally returns "[Native Object]", the object can be reimplemented according to its own characteristics

1
String HeapGraphEdge.toString();

Return result:

• String , returns a string representation of the object

toJSON

Returns the JSON format representation of the object, generally returns a collection of readable attributes defined by the object

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

Call parameters:

• key : String, unused

Return result:

• Value , returns a value containing JSON serializable
