Method: MIME::Type#initialize

Defined in:
lib/mime/type.rb

#initialize(content_type) {|_self| ... } ⇒ Type

Builds a MIME::Type object from the content_type, a MIME Content Type value (e.g., “text/plain” or “application/x-eruby”). The constructed object is yielded to an optional block for additional configuration, such as associating extensions and encoding information.

  • When provided a Hash or a MIME::Type, the MIME::Type will be constructed with #init_with.

There are two deprecated initialization forms:

  • When provided an Array, the MIME::Type will be constructed using the first element as the content type and the remaining flattened elements as extensions.

  • Otherwise, the content_type will be used as a string.

Yields the newly constructed self object.

Yields:

  • (_self)

Yield Parameters:

  • _self (MIME::Type) —

    the object that the method was called on
