base

Data transformer interfaces.

class pysatl_cpd.data.providers.transformers.base.IDataTransformer[source]

Abstract source class for data transformers.

Defines the interface for transforming data providers from one type to another through a transform operation.

abstractmethod transform(provider)[source]

Transform input data provider to output data provider.

Parameters:: provider (TypeVar(DataProviderInT, bound= DataProvider[Any, Any])) – Input data provider to transform.
Returns:: Transformed data provider.
Return type:: TypeVar(DataProviderOutT, bound= DataProvider[Any, Any])

abstract property annotation: str

Transformer annotation.

__and__(other)[source]

Compose this transformer with another transformer.

Parameters:: other (IDataTransformer[TypeVar(DataProviderOutT, bound= DataProvider[Any, Any]), TypeVar(DataProviderFinalT, bound= DataProvider[Any, Any])]) – Transformer applied after this transformer.
Returns:: Composed transformer applying both transforms in order.
Return type:: ComposedTransformer[TypeVar(DataProviderInT, bound= DataProvider[Any, Any]), TypeVar(DataProviderFinalT, bound= DataProvider[Any, Any])]

Return a stable hash derived from the transformer annotation.

class pysatl_cpd.data.providers.transformers.base.ComposedTransformer(*transformers)[source]

Transformer composed of multiple transformers applied in sequence.

Applies each transformer to the result of the previous one, chaining transformations together.

Parameters:: *transformers (IDataTransformer[DataProvider, DataProvider]) – Variable-length list of transformers to apply in order.
Raises:: ValueError – If no transformers are provided.

__init__(*transformers)[source]

Parameters:: transformers (IDataTransformer[DataProvider, DataProvider])
Return type:: None

transform(provider)[source]

Apply all transformers in sequence to the input provider.

Parameters:: provider (TypeVar(DataProviderInT, bound= DataProvider[Any, Any])) – Input data provider to transform.
Returns:: Data provider after all transformations applied.
Return type:: TypeVar(DataProviderOutT, bound= DataProvider[Any, Any])

__and__(other)[source]

Append another transformer to the composition.

Parameters:: other (IDataTransformer[TypeVar(DataProviderOutT, bound= DataProvider[Any, Any]), TypeVar(DataProviderFinalT, bound= DataProvider[Any, Any])]) – Transformer applied after the current composition.
Returns:: Extended composed transformer.
Return type:: ComposedTransformer[TypeVar(DataProviderInT, bound= DataProvider[Any, Any]), TypeVar(DataProviderFinalT, bound= DataProvider[Any, Any])]

property annotation: str

Composed transformer annotation.
