Constructor Details

RegionServiceRegionResolver

public RegionServiceRegionResolver(RegionServiceRegionResolver.RegionServiceResolver<T> resolver)

Constructs a new instance of RegionServiceRegionResolver initialized with the given RegionServiceRegionResolver.RegionServiceResolver.

Parameters:

resolver - RegionServiceRegionResolver.RegionServiceResolver used to resolve the RegionService that is used to resolve cache Regions by name.

Throws:

IllegalArgumentException - if RegionServiceRegionResolver.RegionServiceResolver is null.

• RegionServiceRegionResolver.RegionServiceResolver

Method Details

from

@NonNull
public static <S extends GemFireCache>
RegionServiceRegionResolver<S> from(@NonNull
 CacheResolver<S> cacheResolver)

Factory method used to construct a RegionServiceRegionResolver from a CacheResolver. The CacheResolver will resolve an instance of GemFireCache, such as a peer Cache or a ClientCache, which is a RegionService capable of resolving a Region identified by name.

Type Parameters:

S - subclass of GemFireCache.

Parameters:

cacheResolver - CacheResolver used to resolve the RegionService.

Returns:

a new instance of RegionServiceRegionResolver.

Throws:

IllegalArgumentException - if CacheResolver is null.

@NonNull
public static RegionServiceRegionResolver<RegionService> from(@Nullable
 RegionService regionService)

Factory method used to construct a RegionServiceRegionResolver initialized with the given RegionService. The RegionService may be an instance of GemFireCache, such as a peer Cache or ClientCache.

Parameters:

regionService - RegionService used to resolve cache Regions identified by name; may be null.

Returns:

a new instance of RegionServiceRegionResolver.

See Also:

• RegionServiceRegionResolver(RegionServiceResolver)
• RegionService

getRegionServiceResolver

protected RegionServiceRegionResolver.RegionServiceResolver<T> getRegionServiceResolver()

Returns the configured RegionServiceRegionResolver.RegionServiceResolver used to resolve the RegionService that is then used to resolve cache Regions by name.

Returns:

the configured RegionServiceRegionResolver.RegionServiceResolver.

See Also:

• RegionServiceRegionResolver.RegionServiceResolver

doResolve

@Nullable
protected <K,
V> Region<K,V> doResolve(@Nullable
 String regionName)

Resolves a cache Region identified by the given name using the configured RegionService resolved from the RegionServiceRegionResolver.RegionServiceResolver.

Specified by:

doResolve in class AbstractCachingRegionResolver

Type Parameters:

K - type of the Region key.

V - type of the Region value.

Parameters:

regionName - name of the Region to resolve.

Returns:

the resolved cache Region identified by the given name; may be null.
