All Known Implementing Classes:

GuavaCacheManager
```
public interface CacheManager
```
A generic cache manager API implemented by different caching backends. Each cache should be made accessible using the Java Map interface.

- Method Detail
  - getNodeCache
```
Map<Long,KiWiNode> getNodeCache()
```
    Return the node id -> node cache from the cache manager. This cache is heavily used to lookup nodes when querying or loading triples and should therefore have a decent size (default 500.000 elements).
    
    Returns:
    an EHCache Cache instance containing the node id -> node mappings
  - getTripleCache
```
Map<Long,KiWiTriple> getTripleCache()
```
    Return the triple id -> triple cache from the cache manager. This cache is used for speeding up the construction of query results.
    
    Returns:
  - getUriCache
```
Map<String,KiWiUriResource> getUriCache()
```
    Return the uri -> KiWiUriResource cache from the cache manager. This cache is used when constructing new KiWiUriResources to avoid a database lookup.
    
    Returns:
  - getBNodeCache
```
Map<String,KiWiAnonResource> getBNodeCache()
```
    Return the anonId -> KiWiAnonResource cache from the cache manager. This cache is used when constructing new KiWiAnonResources to avoid a database lookup.
    
    Returns:
  - getLiteralCache
```
Map<String,KiWiLiteral> getLiteralCache()
```
    Return the literal cache key -> KiWiLiteral cache from the cache manager. This cache is used when constructing new KiWiLiterals to avoid a database lookup.
    
    Returns:
    See Also:
    LiteralCommons.createCacheKey(String, java.util.Locale, String)
  - getNamespaceUriCache
```
Map<String,KiWiNamespace> getNamespaceUriCache()
```
    Return the URI -> namespace cache from the cache manager. Used for looking up namespaces
    
    Returns:
  - getNamespacePrefixCache
```
Map<String,KiWiNamespace> getNamespacePrefixCache()
```
    Return the prefix -> namespace cache from the cache manager. Used for looking up namespaces
    
    Returns:
  - getRegistryCache
```
Map<Long,Long> getRegistryCache()
```
    Create and return the cache used by the CacheTripleRegistry. This is an unlimited synchronous replicated cache and should be used with care.
    
    Returns:
  - getCacheByName
```
Map getCacheByName(String name)
```
    Get the cache with the given name from the cache manager. Can be used to request additional caches from the cache manager that are not covered by explicit methods.
    
    Parameters:
    name -
    
    Returns:
  - clear
```
void clear()
```
    Clear all caches managed by this cache manager.
  - shutdown
```
void shutdown()
```
    Shutdown this cache manager instance. Will shutdown the underlying EHCache cache manager.
