#parse_block(opts = {}) ⇒ Object

Parses a statement’s block with a set of state values. If the statement has no block, nothing happens. A description of state values can be found at Base#push_state

Parameters:

  • opts (Hash) (defaults to: {}) —

    State options

Options Hash (opts):

  • :namespace (CodeObjects::NamespaceObject) — default: value of #namespace —

    the namespace object that Base#namespace will be equal to for the duration of the block.

  • :scope (Symbol) — default: :instance —

    the scope for the duration of the block.

  • :owner (CodeObjects::Base) — default: value of #owner —

    the owner object (method) for the duration of the block
