Class Method Details

.base_config(name, accept_value: true) ⇒ Object

Generates a very basic configuration method which accepts a block or input value (see options)

Parameters:

  • name (Object) —

    The configuration’s name which will become the method name

  • accept_value (Boolean) (defaults to: true) —

    If set to true, the resulting method accepts not only a block, but also a direct value. If both, a value and a block are given, the block takes precedence
