Constructor Detail

DerivationConfigWithExpr

public DerivationConfigWithExpr(java.util.List<java.lang.String> keys,
                                java.util.Map<java.lang.String,KeyedFeature> inputs,
                                TypedExpr typedDefinition)

Constructor

Parameters:

keys - The key of the derived feature; can be single or composite key.

inputs - The parent feature(s) from whom this feature is derived. It is expressed as a java.util.Map of argument name to KeyedFeature

typedDefinition - A user-defined expression which defines the derived feature using the argument names from the inputs, together with the ExprType
