Conditional¶

Declaration¶

class enaml.core.conditional.Conditional(parent=None, **kwargs)[source]¶

Bases: Pattern

A pattern object that represents conditional objects.

When the condition attribute is True, the conditional will create its child items and insert them into its parent; when False, the old items will be destroyed.

Attributes:

children

condition

destroyed

initialized

is_destroyed

is_initialized

items

name

parent

pattern_nodes

Methods

child_added(child)	An overridden child added event handler.
child_moved(child)	A method invoked when a child is moved in the object.
child_node_intercept(nodes, key, f_locals)	Add a child subtree to this pattern.
child_removed(child)	A method invoked when a child is removed from the object.
destroy()	A reimplemented destructor.
find(name[, regex])	Find the first object in the subtree with the given name.
find_all(name[, regex])	Find all objects in the subtree with the given name.
freeze	Freeze the atom to prevent further modifications to its attributes.
get_member	Get the named member for the atom.
has_observer	Get whether the atom has the given observer for a given topic.
has_observers	Get whether the atom has observers for a given topic.
initialize()	A reimplemented initialization method.
insert_children(before, insert)	Insert children into this object at the given location.
members()	Get the members dictionary for the type.
notifications_enabled	Get whether notification is enabled for the atom.
notify	Call the registered observers for a given topic with positional and keyword arguments.
observe	Register an observer callback to observe changes on the given topic(s).
parent_changed(old, new)	A method invoked when the parent of the object changes.
pattern_items()	Get a list of items created by the pattern.
refresh_items()	Refresh the items of the pattern.
root_object()	Get the root object for this hierarchy.
set_notifications_enabled	Enable or disable notifications for the atom.
set_parent(parent)	Set the parent for this object.
suppress_notifications()	Disable member notifications within in a context.
traverse([depth_first])	Yield all of the objects in the tree, from this object down.
traverse_ancestors([root])	Yield all of the objects in the tree, from this object up.
unobserve	Unregister an observer callback for the given topic(s).

condition¶

The condition variable. If this is True, a copy of the children will be inserted into the parent. Otherwise, the old copies will be destroyed.

destroy()[source]¶

A reimplemented destructor.

The conditional will release the owned items on destruction.

items¶

The list of items created by the conditional. This list should not be manipulated directly by user code.

pattern_items()[source]¶

Get a list of items created by the pattern.

refresh_items()[source]¶

Refresh the items of the pattern.

This method destroys the old items and creates and initializes the new items.
