    A factory for constructing encoders that convert objects and primitives to and from the internal row format using catalyst expressions and code generation.

    A factory for constructing encoders that convert objects and primitives to and from the internal row format using catalyst expressions and code generation. By default, the expressions used to retrieve values from an input row when producing an object will be created as follows:

    • Classes will have their sub fields extracted by name using UnresolvedAttribute expressions and UnresolvedExtractValue expressions.
    • Tuples will have their subfields extracted by position using BoundReference expressions.
    • Primitives will have their values extracted from the first ordinal with a schema that defaults to the name value.

class Serializer[T] extends (T) ⇒ InternalRow with Serializable

Function that serializesa an object of type T to an InternalRow. This class is not thread-safe. Note that multiple calls to apply(..) return the same actual InternalRow object. Thus, the caller should copy the result before making another call if required.
