mvpa2.base.state.ConditionalAttributesCollection

class mvpa2.base.state.ConditionalAttributesCollection(items=None, name=None)

Container of ConditionalAttributes for a stateful object.

Groups:

• Public Access Functions: has_key, is_enabled, is_active
• Access Implementors: listing, names, _get_enabled
• Mutators: __init__, enable, disable, _set_enabled
• R/O Properties: listing, names, items
• R/W Properties: enabled

Methods

change_temporarily([enable_ca, disable_ca, ...])	Temporarily enable/disable needed ca for computation
clear(() -> None.  Remove all items from D.)
copy(*args, **kwargs)	Create a copy of a collection.
disable(key)	Disable conditional attribute defined by key id
enable(key[, value, missingok])	Enable conditional attribute given in key
fromkeys(...)	v defaults to None.
get((k[,d]) -> D[k] if k in D, ...)
has_key((k) -> True if D has a key k, else False)
is_active(key)	Returns True if state key is known and is enabled
is_enabled(key)	Returns True if state key is enabled
is_set([key])	If item (or any in the present or listed) was set
items(() -> list of D’s (key, value) pairs, ...)
iteritems(() -> an iterator over the (key, ...)
iterkeys(() -> an iterator over the keys of D)
itervalues(...)
keys(() -> list of D’s keys)
pop((k[,d]) -> v, ...)	If key is not found, d is returned if given, otherwise KeyError is raised
popitem(() -> (k, v), ...)	2-tuple; but raise KeyError if D is empty.
reset([key])	Reset the conditional attribute defined by key
reset_changed_temporarily()	Reset to previousely stored set of enabled ca
setdefault((k[,d]) -> D.get(k,d), ...)
values(() -> list of D’s values)
viewitems(...)
viewkeys(...)
viewvalues(...)
which_set()	Return list of keys which were set

Initialize the conditional attributes of a derived class

Parameters:

items : dict

dictionary of ca

name : str

literal description. Usually just attribute name for the collection, e.g. ‘ca’

change_temporarily(enable_ca=None, disable_ca=None, other=None)

Temporarily enable/disable needed ca for computation

Enable or disable ca which are enabled in other and listed in enable _ca. Use reset_enabled_temporarily to reset to previous state of enabled.

other can be a ClassWithCollections object or ConditionalAttributesCollection

disable(key)

Disable conditional attribute defined by key id

enable(key, value=True, missingok=False)

Enable conditional attribute given in key

enabled

Return list of enabled ca

Parameters:

nondefault : bool

Either to return also ca which are enabled simply by default

invert : bool

Would invert the meaning, ie would return disabled ca

is_active(key)

Returns True if state key is known and is enabled

is_enabled(key)

Returns True if state key is enabled

reset_changed_temporarily()

Reset to previousely stored set of enabled ca
