Member Function Documentation

const HeapGraphEdge* GetChild ( int  index) const

Retrieves a child by index.

int GetChildrenCount ( ) const

Returns child nodes count of the node.

Handle<Value> GetHeapValue ( ) const

Finds and returns a value from the heap corresponding to this node, if the value is still reachable.

SnapshotObjectId GetId ( ) const

Returns node id. For the same heap object, the id remains the same across all snapshots.

Handle<String> GetName ( ) const

Returns node name. Depending on node's type this can be the name of the constructor (for objects), the name of the function (for closures), string value, or an empty string (for compiled code).

int GetSelfSize ( ) const

Returns node's own size, in bytes.

Type GetType ( ) const

Returns node type (see HeapGraphNode::Type).
