Inheritance diagram of ThreadDict
class ThreadDict(other=None, read_method=None, write_method=None, timewait=0.1, threaded=True)[source]

Thread safe dictionary with redefinable read/write methods and a background thread for hardware update. All methods are thread-safe using @self_lock decorator.


any method decorated in this way CANNOT call other decorated methods! All values of the dictionary will be automatically updated in a separate Thread using read_method provided. Any value overwritten in the dict should launch the write_method.


a[2] equals to a[2]=read_method(2)
a[2]=1 equals to a[2]=write_method(2,1)

Import from taurus.core.util.containers as:

from taurus.core.util.containers import ThreadDict
append(*args, **kwargs)[source]
copy() a shallow copy of D
get(*args, **kwargs)[source]

Return the value for key if key is in the dictionary, else default.

get_last_cycle_start(*args, **kwargs)[source]
get_last_update(*args, **kwargs)[source]
get_timewait(*args, **kwargs)[source]
items() a set-like object providing a view on D's items
keys() a set-like object providing a view on D's keys
pop(k[, d]) v, remove specified key and return the corresponding value.

If key is not found, default is returned if given, otherwise KeyError is raised

set_last_cycle_start(*args, **kwargs)[source]
set_last_update(*args, **kwargs)[source]
set_timewait(*args, **kwargs)[source]
threadkeys(*args, **kwargs)[source]
update([E, ]**F) None.  Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() an object providing a view on D's values
