Member Function Documentation

Dispose()

virtual void v8::internal::NativeGroupRetainedObjectInfo::Dispose ( )

inlinevirtual

Called by V8 when it no longer needs an instance.

Implements v8::RetainedObjectInfo.

Definition at line 2441 of file heap-snapshot-generator.cc.

                         {
    CHECK(!disposed_);
    disposed_ = true;
    delete this;
  }

References CHECK, and disposed_.

GetHash()

virtual intptr_t v8::internal::NativeGroupRetainedObjectInfo::GetHash ( )

inlinevirtual

Returns hash value for the instance.

Equivalent instances must have the same hash value.

Implements v8::RetainedObjectInfo.

Definition at line 2449 of file heap-snapshot-generator.cc.

{ return hash_; }

References hash_.

GetLabel()

virtual const char* v8::internal::NativeGroupRetainedObjectInfo::GetLabel ( )

inlinevirtual

Returns human-readable label.

It must be a null-terminated UTF-8 encoded string. V8 copies its contents during a call to GetLabel.

Implements v8::RetainedObjectInfo.

Definition at line 2450 of file heap-snapshot-generator.cc.

{ return label_; }

References label_.

IsEquivalent()

virtual bool v8::internal::NativeGroupRetainedObjectInfo::IsEquivalent ( RetainedObjectInfo *  other )

inlinevirtual

Returns whether two instances are equivalent.

Implements v8::RetainedObjectInfo.

Definition at line 2446 of file heap-snapshot-generator.cc.

                                                       {
    return hash_ == other->GetHash() && !strcmp(label_, other->GetLabel());
  }
