Member Documentation

activate()[source]: Set the active attribute to True

active_blocks(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The active_blocks method is deprecated. Use the Block.block_data_objects() method.

active_component_data(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The active_component_data method is deprecated. Use the Block.component_data_objects() method.

active_components(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The active_components method is deprecated. Use the Block.component_objects() method.

add_component(name, val)

Add a component ‘name’ to the block.

This method assumes that the attribute is not in the model.

all_blocks(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The all_blocks method is deprecated. Use the Block.block_data_objects() method.

all_component_data(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The all_component_data method is deprecated. Use the Block.component_data_objects() method.

all_components(*args, **kwargs): DEPRECATED.

Deprecated since version 4.1.10486: The all_components method is deprecated. Use the Block.component_objects() method.

block_data_objects(active=None, sort=False, descend_into=True, descent_order=None)

Returns this block and any matching sub-blocks.

This is roughly equivalent to

iter(block for block in itertools.chain(
     [self], self.component_data_objects(descend_into, ...))
     if block.active == active)

Notes

The self block is always returned, regardless of the types indicated by descend_into.

The active flag is enforced on all blocks, including self.

Parameters:

active (None or bool) – If not None, filter components by the active flag
sort (None or bool or SortComponents) – Iterate over the components in a specified sorted order
descend_into (None or type or iterable) – Specifies the component types (ctypes) to return and to descend into. If True or None, defaults to (Block,). If False, only self is returned.
descent_order (None or TraversalStrategy) – The strategy used to walk the block hierarchy. Defaults to TraversalStrategy.PrefixDepthFirstSearch.

Return type:

tuple or generator

clear_suffix_value(suffix_or_name, expand=True): Set the suffix value for this component data

clone(memo=None): TODO

cname(*args, **kwds): DEPRECATED.

Deprecated since version 5.0: The cname() method has been renamed to getname(). The preferred method of obtaining a component name is to use the .name property, which returns the fully qualified component name. The .local_name property will return the component name only within the context of the immediate parent container.

collect_ctypes(active=None, descend_into=True)

Count all component types stored on or under this block.

Parameters:

active (True/None) – Set to True to indicate that only active components should be counted. The default value of None indicates that all components (including those that have been deactivated) should be counted.
descend_into (bool) – Indicates whether or not component types should be counted on sub-blocks. Default is True.

Returns: A set of component types.

component(name_or_object)

Return a child component of this block.

If passed a string, this will return the child component registered by that name. If passed a component, this will return that component IFF the component is a child of this block. Returns None on lookup failure.

component_data_iterindex(ctype=None, active=None, sort=False, descend_into=True, descent_order=None)

DEPRECATED.

Return a generator that returns a tuple for each component data object in a block. By default, this generator recursively descends into sub-blocks. The tuple is

((component name, index value), ComponentData)

Deprecated since version 6.6.0: The component_data_iterindex method is deprecated. Components now know their index, so it is more efficient to use the Block.component_data_objects() method followed by .index().

component_data_objects(ctype=None, active=None, sort=False, descend_into=True, descent_order=None): Return a generator that iterates through the component data objects for all components in a block. By default, this generator recursively descends into sub-blocks.

component_map(ctype=None, active=None, sort=False)

Returns a PseudoMap of the components in this block.

Parameters:

ctype (None or type or iterable) –
Specifies the component types (ctypes) to include in the resulting PseudoMap

None

All components

type

A single component type

iterable

All component types in the iterable
active (None or bool) –
Filter components by the active flag

None

Return all components

True

Return only active components

False

sort (bool) –
Iterate over the components in a sorted order

True

Iterate using Block.alphabetizeComponentAndIndex

False

Iterate using Block.declarationOrder

component_objects(ctype=None, active=None, sort=False, descend_into=True, descent_order=None): Return a generator that iterates through the component objects in a block. By default, the generator recursively descends into sub-blocks.

contains_component(ctype): Return True if the component type is in _ctypes and … TODO.

deactivate()[source]: Set the active attribute to False

del_component(name_or_object): Delete a component from this block.

display(filename=None, ostream=None, prefix=''): Print the Pyomo model in a verbose format.

find_component(label_or_component)

Returns a component in the block given a name.

Parameters:: label_or_component (str, Component, or ComponentUID) – The name of the component to find in this block. String or Component arguments are first converted to ComponentUID.
Returns:: Component on the block identified by the ComponentUID. If a matching component is not found, None is returned.
Return type:: Component

get_suffix_value(suffix_or_name, default=None): Get the suffix value for this component data

getname(fully_qualified=False, name_buffer=None, relative_to=None): Return a string with the component name and index

index(): Returns the index of this ComponentData instance relative to the parent component index set. None is returned if this instance does not have a parent component, or if - for some unknown reason - this instance does not belong to the parent component’s index set.

is_component_type(): Return True if this class is a Pyomo component

is_constructed(): A boolean indicating whether or not all active components of the input model have been properly constructed.

is_expression_type(expression_system=None): Return True if this numeric value is an expression

pprint(ostream=None, verbose=False, prefix='')

Print component information

Note that this method is generally only reachable through ComponentData objects in an IndexedComponent container. Components, including unindexed Component derivatives and both scalar and indexed IndexedComponent derivatives will see Component.pprint()

reclassify_component_type(name_or_object, new_ctype, preserve_declaration_order=True): TODO

set_suffix_value(suffix_or_name, value, expand=True): Set the suffix value for this component data

transfer_attributes_from(src)

Transfer user-defined attributes from src to this block

This transfers all components and user-defined attributes from the block or dictionary src and places them on this Block. Components are transferred in declaration order.

If a Component on src is also declared on this block as either a Component or attribute, the local Component or attribute is replaced by the incoming component. If an attribute name on src matches a Component declared on this block, then the incoming attribute is passed to the local Component’s set_value() method. Attribute names appearing in this block’s _Block_reserved_words set will not be transferred (although Components will be).

Parameters:: src (BlockData or dict) – The Block or mapping that contains the new attributes to assign to this block.

type()

DEPRECATED.

Return the class type for this component

Deprecated since version 5.7: Component.type() method has been replaced by the .ctype property.

valid_problem_types(): This method allows the pyomo.opt convert function to work with a Model object.

property active: Return the active attribute

property ctype: Return the class type for this component

property local_name: Get the component name only within the context of the immediate parent container.

property name: Get the fully qualified component name.
