### *class* compolyx.ButtJointSequence(graph, obj, parent=None)

Represents the butt-joint sequence.

### Attributes

NameDescription[`ButtJointSequence.active`](compolyx.ButtJointSequence.active.md#compolyx.ButtJointSequence.active)Indicates whether the sequence entity is active.[`ButtJointSequence.enabled`](compolyx.ButtJointSequence.enabled.md#compolyx.ButtJointSequence.enabled)Indicates whether the object is enabled.[`ButtJointSequence.global_ply_nr`](compolyx.ButtJointSequence.global_ply_nr.md#compolyx.ButtJointSequence.global_ply_nr)[`ButtJointSequence.id`](compolyx.ButtJointSequence.id.md#compolyx.ButtJointSequence.id)ID of the object.[`ButtJointSequence.is_dict_item`](compolyx.ButtJointSequence.is_dict_item.md#compolyx.ButtJointSequence.is_dict_item)Indicates whether the object is an item in a dictionary.[`ButtJointSequence.is_list_item`](compolyx.ButtJointSequence.is_list_item.md#compolyx.ButtJointSequence.is_list_item)Indicates whether the object is an item of a list.[`ButtJointSequence.link_path`](compolyx.ButtJointSequence.link_path.md#compolyx.ButtJointSequence.link_path)Root path of the current node in the tree for links to this object.[`ButtJointSequence.name`](compolyx.ButtJointSequence.name.md#compolyx.ButtJointSequence.name)Name of the object.[`ButtJointSequence.parent`](compolyx.ButtJointSequence.parent.md#compolyx.ButtJointSequence.parent)Parent object in the tree.[`ButtJointSequence.primary_plies`](compolyx.ButtJointSequence.primary_plies.md#compolyx.ButtJointSequence.primary_plies)Primary plies of the butt joint sequence.[`ButtJointSequence.root_path`](compolyx.ButtJointSequence.root_path.md#compolyx.ButtJointSequence.root_path)Root path of the current node in the tree.[`ButtJointSequence.secondary_plies`](compolyx.ButtJointSequence.secondary_plies.md#compolyx.ButtJointSequence.secondary_plies)Secondary plies of the butt joint sequence.[`ButtJointSequence.status`](compolyx.ButtJointSequence.status.md#compolyx.ButtJointSequence.status)Status of the object.[`ButtJointSequence.status_changed`](compolyx.ButtJointSequence.status_changed.md#compolyx.ButtJointSequence.status_changed)Boolean flag which is set to true in C++ when up-to-date status of object changes.[`ButtJointSequence.uid`](compolyx.ButtJointSequence.uid.md#compolyx.ButtJointSequence.uid)UID of the object.[`ButtJointSequence.vertex`](compolyx.ButtJointSequence.vertex.md#compolyx.ButtJointSequence.vertex)Raises an error if the object has been removed from the graph.### Methods

NameDescription[`ButtJointSequence.find_parent`](compolyx.ButtJointSequence.find_parent.md#compolyx.ButtJointSequence.find_parent)(type)Steps up the tree and returns the first parent with given type.[`ButtJointSequence.obj_exists`](compolyx.ButtJointSequence.obj_exists.md#compolyx.ButtJointSequence.obj_exists)()Checks if \_\_obj still references the c++ object (has not been reset to None by self.\_delete) and exists in the graph.[`ButtJointSequence.serialize`](compolyx.ButtJointSequence.serialize.md#compolyx.ButtJointSequence.serialize)()Serialize to Python string.[`ButtJointSequence.serialize_name_and_id`](compolyx.ButtJointSequence.serialize_name_and_id.md#compolyx.ButtJointSequence.serialize_name_and_id)()Serializes the name and ID.[`ButtJointSequence.update`](compolyx.ButtJointSequence.update.md#compolyx.ButtJointSequence.update)()[`ButtJointSequence.visit`](compolyx.ButtJointSequence.visit.md#compolyx.ButtJointSequence.visit)(visitor)Walk through the tree and let the visitor perform action on every descendant node.
