__add__()

__getitem__()

Returns the nth Material in the collection. This is the same as get_material(), but it may be a more convenient way to access it.

__iadd__()

__init__()

add_material()

Adds a new Material to the collection.

add_materials_from()

Adds all the Materials indicated in the other collection to this material. The other materials are simply appended to the end of the materials in this list; duplicates are not automatically removed.

assign()

clear()

Removes all Materials from the collection.

find_material()

Returns the material in the collection with the indicated name, if any, or NULL if no material has that name.

get_material()

Returns the nth Material in the collection.

get_num_materials()

has_material()

Returns true if the indicated Material appears in this collection, false otherwise.

output()

Writes a brief one-line description of the MaterialCollection to the indicated output stream.

remove_duplicate_materials()

Removes any duplicate entries of the same Materials on this collection. If a Material appears multiple times, the first appearance is retained; subsequent appearances are removed.

remove_material()

remove_materials_from()

Removes from this collection all of the Materials listed in the other collection.

size()

Returns the number of materials in the collection. This is the same thing as get_num_materials().
