Member Function Documentation

◆ GetNativeObject()

virtual NativeObject GetNativeObject ( )
inlinevirtual

Returns the NativeObject that can be used for querying the |HeapSnapshot|.

Definition at line 754 of file v8-profiler.h.

◆ IsEmbedderNode()

virtual bool IsEmbedderNode ( )
inlinevirtual

Must return true for non-V8 nodes.

Definition at line 744 of file v8-profiler.h.

◆ IsRootNode()

virtual bool IsRootNode ( )
inlinevirtual

Definition at line 742 of file v8-profiler.h.

◆ Name()

virtual const char* Name ( )
pure virtual

◆ NamePrefix()

virtual const char* NamePrefix ( )
inlinevirtual

Optional name prefix. It is used in Chrome for tagging detached nodes.

◆ operator=()

Node& operator= ( const Node )
delete

◆ SizeInBytes()

virtual size_t SizeInBytes ( )
pure virtual

◆ WrapperNode()

virtual Node* WrapperNode ( )
inlinevirtual

The corresponding V8 wrapper node if not null. During heap snapshot generation the embedder node and the V8 wrapper node will be merged into one node to simplify retaining paths.
