MapperIK, IV, MK, MV Class

[SerializableAttribute]
public abstract class Mapper<IK, IV, MK, MV>

<SerializableAttribute>
Public MustInherit Class Mapper(Of IK, IV, MK, MV)

Type Parameters

IK

Input key type.

IV

Input value type.

MK

Map output (intermediate) key type.

MV

Map output (intermediate) value type.

The MapperIK, IV, MK, MV type exposes the following members.

	Name	Description
	MapperIK, IV, MK, MV	Initializes a new instance of the MapperIK, IV, MK, MV class

	Name	Description
	KeyOutputSerializer	Gets/sets CustomSerializerT for serializing and deserializing the intermediate mapper's output keys. If CustomSerializerT is not assigned, the default BinaryFormatter serializer will be used.
	ValueOutputSerializer	Gets/sets the CustomSerializerT for serializing and deserializing the intermediate mapper's output values. If CustomSerializerT is not assigned, the default BinaryFormatter serializer will be used.

	Name	Description
	Cleanup	Performs optional cleanup operations after the Map(IK, IV, IContextMK, MV) method is invoked.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Map	Performs the map operation for a key-value pair.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Setup	Performs optional setup operations before the Map(IK, IV, IContextMK, MV) method is invoked.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

By default, the mapper class uses the BinaryFormatter serializer for emitted intermediate keys and values, but for the best performance you may want to consider overiding the KeyOutputSerializer and ValueOutputSerializer properties and use serializers with more compact output (for example, serializers that implement the Protocol Buffers or MessagePack serialization format).
