#describe_mixin(name, type = nil) ⇒ Occi::Core::Mixin?

Looks up a mixin using its name and, optionally, a type as well. Will return mixin's full description.

Examples:

client.describe_mixin "debian6"
 # => #<Occi::Core::Mixin>
client.describe_mixin "debian6", "os_tpl"
 # => #<Occi::Core::Mixin>
client.describe_mixin "large", "resource_tpl"
 # => #<Occi::Core::Mixin>
client.describe_mixin "debian6", "resource_tpl" # => nil

Parameters:

  • name (String) —

    name of the mixin

  • type (String) (defaults to: nil) —

    type of the mixin

Returns:

  • (Occi::Core::Mixin, nil) —
