Member Function Documentation

◆ AddEdge()

void v8::internal::EmbedderGraphImpl::AddEdge	(	Node *	from,
		Node *	to,
		const char *	name )

inlinefinalvirtual

Adds an edge that represents a strong reference from the given node |from| to the given node |to|. The nodes must be added to the graph before calling this function.

If name is nullptr, the edge will have auto-increment indexes, otherwise it will be named accordingly.

Implements v8::EmbedderGraph.

Definition at line 3014 of file heap-snapshot-generator.cc.

◆ AddNativeSize()

void v8::internal::EmbedderGraphImpl::AddNativeSize ( size_t size )

inlinefinalvirtual

Adds a count of bytes that are not associated with any particular Node. An embedder may use this to represent the size of nodes which were omitted from this EmbedderGraph despite being retained by the graph, or other overhead costs. This number will contribute to the total size in a heap snapshot, without being represented in the object graph.

Reimplemented from v8::EmbedderGraph.

Definition at line 3018 of file heap-snapshot-generator.cc.

◆ AddNode()

Node * v8::internal::EmbedderGraphImpl::AddNode ( std::unique_ptr< Node > node )

inlinefinalvirtual

Adds the given node to the graph and takes ownership of the node. Returns a raw pointer to the node that is valid while the graph is alive.

Implements v8::EmbedderGraph.

Here is the caller graph for this function:

◆ edges()

const std::vector< Edge > & v8::internal::EmbedderGraphImpl::edges ( )

inline

◆ native_size()

size_t v8::internal::EmbedderGraphImpl::native_size ( ) const

inline

Definition at line 3019 of file heap-snapshot-generator.cc.

◆ nodes()

const std::vector< std::unique_ptr< Node > > & v8::internal::EmbedderGraphImpl::nodes ( )

inline

Definition at line 3021 of file heap-snapshot-generator.cc.

◆ V8Node() [1/2]

Node * v8::internal::EmbedderGraphImpl::V8Node ( const v8::Local< v8::Data > & value )

inlinefinalvirtual

Returns a node corresponding to the given V8 value. Ownership is not transferred. The result pointer is valid while the graph is alive.

For API compatibility, this default implementation just checks that the data is a v8::Value and forward it to the variant that takes v8::Value, which is currently required to be implemented. In the future we'll remove the v8::Value variant, and make this variant that takes v8::Data abstract instead. If the embedder subclasses v8::EmbedderGraph and also use v8::TracedReference<v8::Data>, they must override this variant.

Reimplemented from v8::EmbedderGraph.

Here is the call graph for this function:

◆ V8Node() [2/2]

Node * v8::internal::EmbedderGraphImpl::V8Node ( const v8::Local< v8::Value > & value )

inlinefinalvirtual

Returns a node corresponding to the given V8 value. Ownership is not transferred. The result pointer is valid while the graph is alive.

For now the variant that takes v8::Data is not marked as abstract for compatibility, but embedders who subclass EmbedderGraph are expected to implement it. Then in the implementation of the variant that takes v8::Value, they can simply forward the call to the one that takes v8::Local<v8::Data>.

Implements v8::EmbedderGraph.
