Member Function Documentation

◆ GetChild()

const HeapGraphEdge* GetChild ( int index ) const

Retrieves a child by index.

◆ GetChildrenCount()

int GetChildrenCount ( ) const

Returns child nodes count of the node.

◆ GetDominatorNode()

const HeapGraphNode* GetDominatorNode ( ) const

Returns a dominator node. This is the node that participates in every path from the snapshot root to the current node.

◆ GetHeapValue()

Handle<Value> GetHeapValue ( ) const

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

◆ GetId()

SnapshotObjectId GetId ( ) const

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

◆ GetName()

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).

◆ GetRetainedSize()

int GetRetainedSize ( ) const

Returns node's retained size, in bytes. That is, self + sizes of the objects that are reachable only from this object. In other words, the size of memory that will be reclaimed having this node collected.

◆ GetRetainer()

const HeapGraphEdge* GetRetainer ( int index ) const

Returns a retainer by index.

◆ GetRetainersCount()

int GetRetainersCount ( ) const

Returns retainer nodes count of the node.

◆ GetSelfSize()

int GetSelfSize ( ) const

Returns node's own size, in bytes.

◆ GetType()

Type GetType ( ) const

Returns node type (see HeapGraphNode::Type).
