Method Details

getAlwaysCreateStringInstance

public static StringCacheProvider getAlwaysCreateStringInstance(boolean unbounded)

Get an instance that returns a cache that acts more as a factory, and does no caching internally.

Parameters:

unbounded - Whether the cache should be unbounded (triggering strict symbol management) or bounded

Returns:

The provider instance

getDefaultCacheProvider

public static StringCacheProvider getDefaultCacheProvider(@NotNull
 com.fishlib.configuration.Configuration configuration)

Get a "default" cache provider according to a single capacity property. Determines the default provider from configuration if this hasn't been done already.

Parameters:

configuration - The configuration to fetch the capacity property from

Returns:

A new StringCacheProviders supplying a cache that makes sense for the configured capacity

makeHintDrivenCacheProvider

public static StringCacheProvider makeHintDrivenCacheProvider(@NotNull
 Map<String,String> propertyDictionary,
 @NotNull
 com.fishlib.configuration.Configuration configuration,
 @NotNull
 String hintDrivenStringCachePrefix)

Make a "hint-driven" cache provider according to a list of hint to specifier mappings from a configuration.

Parameters:

propertyDictionary - A dictionary of properties that should be prioritized over configuration properties, e.g. derived from a DataImportServer's data routing entry

configuration - The configuration to fetch hint to specifier properties from

hintDrivenStringCachePrefix - The prefix to use when finding properties

Returns:

A new StringCacheProviders encompassing the configured hints
