51 ///
52 /// Since blobs are opaque to the blob container, it's impossible to create
53 /// blobs when loading. If blobs need to be saved/loaded, a blob loader class
54 /// will have to be used to create blob data from the stream.
55 /// This class should load the data stored by the BlobData::jsonSave() method.

68 /// @brief A simple ATI to store aribtrary "blobs" of data in an attribute
69 ///
70 /// The blob attribute type stores arbitrary blobs (GA_Blob) of data for each
71 /// element in the attribute array. The blobs are stored as reference counted
72 /// shared objects, meaning the blobs may be shared between multiple elements
73 /// of the array. Each blob is referenced by a unique integer handle.
74 ///
75 /// It's also possible to get a list of all the blobs stored by the attribute
76 ///
77 /// By default, the array is filled with NULL pointers.
78 ///
79 /// This class is very simple and only provides a minimal interface. Blob
80 /// attributes are not saved/loaded, and there is minimal access to the blobs.
81 ///
82 /// Users may sub-class from this ATI to create more complicated classes which
83 /// provide alternate interfaces.
84 ///
85 /// This attribute looks for options (GA_Attribute::getOptions())
86 /// - bool blob:stringset (default: true)@n
87 /// This option is queried when merging detail attributes. When true,
88 /// the @b unique blobs from both details will be merged into the resulting
89 /// detail. When false, the resulting detail will only have the blobs from
90 /// the first detail in the merge.
