Public Methods

• ::containsManualSection(string $code): bool
• ::getBeginManualSection(string $id): string
• ::getEndManualSection(): string
• ->__construct(string $code)
• ->assertValidManualSections(): \void
  Validate the manual sections and throws PartiallyGeneratedCodeException if there are any errors (e
• ->extractGeneratedCode(): string
  Extract the generated code and returns it as a string
• ->merge(string $existing_code, ?KeyedContainer<string, Traversable<string>> $rekeys = NULL): string
  Merge the code with the existing code

Private Methods

• ::getBeginManualSectionRegex(string $regex): string
• ->extractManualCode(string $code): dict<string, string>
  Extract manually generated code and returns a map of ids to chunks of code
• ->iterateCodeSections(string $code): \\Generator<int, \tuple<?string, string>, \void>
  Iterates through the code yielding tuples of ($id, $chunk), where $id is the id of the manual section or null if it’s an auto-generated section, and chunk is the code belonging to that section
