Parameters:

dynamicContext - the dynamic context for that evaluation

Returns:

the resulting RDD

createNativeDataFrame

public HomogeneousItemDataFrame createNativeDataFrame(DynamicContext dynamicContext)

Description copied from interface: DataFrameRuntimePlan

Builds the DataFrame for one evaluation.

Specified by:

createNativeDataFrame in interface DataFrameRuntimePlan<Item>

Parameters:

dynamicContext - the dynamic context for that evaluation

Returns:

the resulting DataFrame

getVariableDependencies

public Map<Name,DynamicContext.VariableDependency> getVariableDependencies()

Overrides:

getVariableDependencies in class ItemRuntimePlan
