Method IsInstanceOfClassID

value.go:1181–1189

IsInstanceOfClassID checks if the value is an instance of a specific class ID This provides type-safe class instance checking with double validation

(expectedClassID uint32)

// IsInstanceOfClassID checks if the value is an instance of a specific class ID
// This provides type-safe class instance checking with double validation
func (v *Value) IsInstanceOfClassID(expectedClassID uint32) bool {
	if v == nil || !v.IsObject() {
		return false
	}

	// Only check class ID match - no opaque data requirement
	objClassID := uint32(C.JS_GetClassID(v.ref))
	return objClassID == expectedClassID
}

// GetClassID returns the class ID of the value if it's a class instance
// Returns JS_INVALID_CLASS_ID (0) if not a class instance
