Class BoundReplaceStrategy<T extends FeatureInput,S extends ReplaceStrategy<T>>

Object

BoundReplaceStrategy<T,S>

Type Parameters:

T - feature-input type

S - strategy-type

public class BoundReplaceStrategy<T extends FeatureInput,S extends ReplaceStrategy<T>>
extends Object

Attaches a replacement-strategy to a session lazily.

i.e. the strategy is attached only when first needed.

This is because as the relevant parameters are not available when we need to call the constructor.
