nvflare.fuel.utils.fobs.decomposers.core_decomposers module¶

Decomposers for Python builtin objects.

class DatetimeDecomposer[source]¶

Bases: Decomposer

decompose(target: datetime) → Any[source]¶

Decompose the target into types supported by msgpack or classes with decomposers registered.

Msgpack supports primitives, bytes, memoryview, lists, dicts.

Parameters:: target – The instance to be serialized
Returns:: The decomposed serializable objects

recompose(data: Any) → datetime[source]¶

Reconstruct the object from decomposed components.

Parameters:: data – The decomposed components
Returns:: The reconstructed object

static supported_type()[source]¶

Returns the type/class supported by this decomposer.

Returns:: The class (not instance) of supported type

class OrderedDictDecomposer[source]¶

Bases: Decomposer

decompose(target: OrderedDict) → Any[source]¶

Decompose the target into types supported by msgpack or classes with decomposers registered.

Msgpack supports primitives, bytes, memoryview, lists, dicts.

Parameters:: target – The instance to be serialized
Returns:: The decomposed serializable objects

recompose(data: Any) → OrderedDict[source]¶

Reconstruct the object from decomposed components.

Parameters:: data – The decomposed components
Returns:: The reconstructed object

static supported_type()[source]¶

Returns the type/class supported by this decomposer.

Returns:: The class (not instance) of supported type

class SetDecomposer[source]¶

Bases: Decomposer

decompose(target: set) → Any[source]¶

Decompose the target into types supported by msgpack or classes with decomposers registered.

Msgpack supports primitives, bytes, memoryview, lists, dicts.

Parameters:: target – The instance to be serialized
Returns:: The decomposed serializable objects

recompose(data: Any) → set[source]¶

Reconstruct the object from decomposed components.

Parameters:: data – The decomposed components
Returns:: The reconstructed object

static supported_type()[source]¶

Returns the type/class supported by this decomposer.

Returns:: The class (not instance) of supported type

class TupleDecomposer[source]¶

Bases: Decomposer

decompose(target: tuple) → Any[source]¶

Decompose the target into types supported by msgpack or classes with decomposers registered.

Msgpack supports primitives, bytes, memoryview, lists, dicts.

Parameters:: target – The instance to be serialized
Returns:: The decomposed serializable objects

recompose(data: Any) → tuple[source]¶

Reconstruct the object from decomposed components.

Parameters:: data – The decomposed components
Returns:: The reconstructed object

static supported_type()[source]¶

Returns the type/class supported by this decomposer.

Returns:: The class (not instance) of supported type
