Casts¶

class any2any.base.Cast(**settings)¶

Base class for all casts. This class is virtual, and all subclasses must implement Cast.call().

Available Settings :

from_¶

type. The type to cast from. If not given, the type of the input is used.

to¶

type. The type to cast to.

mm_to_cast¶

dict. {<mm>: <cast>}. A dictionary mapping a metamorphosis to a cast instance.

extra_mm_to_cast¶

dict. {<mm>: <cast>}. Overrides mm_to_cast as a dictionary update.

from_wrapped¶

type. A subclass of any2any.utils.WrappedObject. If provided, will cause from_ to be automatically wrapped.

to_wrapped¶

type. A subclass of any2any.utils.WrappedObject. If provided, will cause to to be automatically wrapped.

logs¶

bool. If True, the cast writes debug informations to the logger.

Members :

call(inpt)¶

Virtual method. Casts inpt.

cast_for(mm)¶

Picks in mm_to_cast a cast suitable for mm, customizes it with calling cast’s settings, and finally returns it.

set_debug_on()¶

Set debug mode: all debug logs will be printed on stderr.

set_debug_off()¶

Toggle debug mode off.

class any2any.base.CastStack(**settings)¶

A cast provided for convenience. CastStack doesn’t do anything else than looking for a suitable cast with Cast.cast_for() and calling it. It is therefore very useful for just stacking a bunch of casts, and then casting different types of input. For example :

>>> cast = CastStack(mm_to_cast={
...     Mm(from_any=int): my_int_cast,
...     Mm(from_any=str): my_str_cast,
... })
>>> cast('a string')
'other string'
>>> cast(1234)
12345

call(inpt, from_=None, to=None) = <unbound method CastStack.call>¶

Settings¶

class any2any.base.Setting(default=None)¶

Base class for all setting types.

customize(cast, value)¶

This method handles customization of the setting’s value.

get(cast)¶

Gets and returns the setting’s value from cast.

inherits(setting)¶

When overriding a setting, this is called on the new setting to take into account the parent setting.

init(cast, value)¶

This method handles initialization of the setting’s value.

set(cast, value)¶

Sets the setting’s value on cast.
