Instance Method Details

#prop ⇒ String

DSL methods can receive either a String or a Proc to calculate the value of the property later on based on the version. We error out if we get both the String and Proc, and we return the value of the property if we do not receive anything.

Parameters:

  • prop_string (String) —

    value to be set in String form

  • block (Proc) —

    value to be set in Proc form

Returns:

  • (String) —

    value of the property

#version(value = nil) ⇒ Object

Sets or retrieves the version for the product. This is used later when we are reading the value of a property if a Proc is specified

#version_for(version_string) ⇒ Mixlib::Version
