#initialize(manifest:, blocks:, block_index_class: BlockIndex) ⇒ Analyzer

Returns a new instance of Analyzer.

Parameters:

  • manifest (Manifest) —

    parsed manifest

  • blocks (Hash{String=>Ucode::Models::Block}) —

    block_id → Block model lookup. Used to construct BlockIndex per gap block.

  • block_index_class (Class) (defaults to: BlockIndex) —

    injectable BlockIndex class for tests
