flexget.utils.lazy_dict module#

class flexget.utils.lazy_dict.LazyCallee(func, keys, args, kwargs)[source]#

Bases: NamedTuple

Parameters:

  • func (Callable)

  • keys (Sequence)

  • args (Sequence)

  • kwargs (Mapping)

classmethod _make(iterable)#

Make a new LazyCallee object from a sequence or iterable

_asdict()#

Return a new dict which maps field names to their values.

_replace(**kwds)#

Return a new LazyCallee object replacing specified fields with new values

_field_defaults = {}#
_fields = ('func', 'keys', 'args', 'kwargs')#
args: Sequence#

Alias for field number 2

func: Callable#

Alias for field number 0

keys: Sequence#

Alias for field number 1

kwargs: Mapping#

Alias for field number 3

class flexget.utils.lazy_dict.LazyDict(*args, **kwargs)[source]#

Bases: MutableMapping

copy()#
get(key, default=None, eval_lazy=True)[source]#

Add the eval_lazy keyword argument to the normal dict.get() method.

Parameters:

  • eval_lazy (bool) – If False, the default will be returned rather than evaluating a lazy field.

  • default (Any)

Return type:

Any

is_lazy(key)[source]#

Return True if value for key is lazy loading.

Parameters:

key – Key to check

Return type:

bool

register_lazy_func(func, keys, args, kwargs)[source]#

Register a list of fields to be lazily loaded by callback func.

Parameters:

  • func (Callable[[Mapping], None]) – Callback function which is called when lazy key needs to be evaluated. Function call will get this LazyDict instance as a parameter. See LazyLookup class for more details.

  • keys (Iterable) – List of key names that func can provide.

  • args (Sequence) – Arguments which will be passed to func when called.

  • kwargs (Mapping) – Keyword arguments which will be passed to func when called.

_abc_impl = <_abc._abc_data object>#
property _lazy_lookup: LazyLookup#

Return the LazyLookup instance for this LazyDict.

If one is already stored in this LazyDict, it is returned, otherwise a new one is instantiated.

class flexget.utils.lazy_dict.LazyLookup(store)[source]#

Bases: object

Store the information to do a lazy lookup for a LazyDict.

An instance is stored as a placeholder value for any key that can be lazily looked up. There should be one instance of this class per LazyDict.

Parameters:

store (LazyDict)

add_func(func, keys, args, kwargs)[source]#
Parameters:

  • func (Callable)

  • keys (Sequence)

  • args (Sequence)

  • kwargs (Mapping)

Return type:

None
