(class from pyomo.core.kernel.sos)

class pyomo.core.kernel.sos.ISOS[source]

Bases: ICategorizedObject

The interface for Special Ordered Sets.

__init__()

Methods

`__init__`()
`activate`()	Activate this object.
`clone`()	Returns a copy of this object with the parent pointer set to `None`.
`deactivate`()	Deactivate this object.
`getname`([fully_qualified, name_buffer, ...])	Dynamically generates a name for this object.
`items`()	Iterator over the sos variables and weights as tuples

Attributes

`active`	The active status of this object.
`ctype`	The object's category type.
`level`	The sos level (e.g., 1,2,...)
`local_name`	The object's local name within the context of its parent.
`name`	The object's fully qualified name.
`parent`	The object's parent (possibly None).
`storage_key`	The object's storage key within its parent
`variables`	The sos variables
`weights`	The sos variables

Member Documentation

activate(): Activate this object.

clone()

Returns a copy of this object with the parent pointer set to None.

A clone is almost equivalent to deepcopy except that any categorized objects encountered that are not descendents of this object will reference the same object on the clone.

deactivate(): Deactivate this object.

getname(fully_qualified=False, name_buffer={}, convert=<class 'str'>, relative_to=None)

Dynamically generates a name for this object.

Parameters:

fully_qualified (bool) – Generate a full name by iterating through all ancestor containers. Default is False.
convert (function) – A function that converts a storage key into a string representation. Default is the built-in function str.
relative_to (object) – When generating a fully qualified name, generate the name relative to this block.

Returns:

If a parent exists, this method returns a string representing the name of the object in the context of its parent; otherwise (if no parent exists), this method returns None.

items()[source]: Iterator over the sos variables and weights as tuples
