Interface PoolResolver

All Known Implementing Classes:

BeanFactoryPoolResolver, PoolManagerPoolResolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface PoolResolver

PoolResolver is a strategy interface for resolving references to Apache Geode Pool instances. This is used throughout SDG's codebase to separate SDG's Pool resolution logic from being explicitly tied to to Apache Geode's static PoolManager class. This interfaces also serves as an SPI for different strategies when resolving a Pool.

Since:

2.3.0

Parameters:

region - Region from which to resolve the associated Pool.

Returns:

the Pool instance associated with the given Region, or the DEFAULT Pool if the Region is a client Region, or null if the Region is not a client Region.
