ReadOnlyClassToSerializerMap (jackson-databind 2.5.0 API)

```
public final class ReadOnlyClassToSerializerMap
extends Object
```
Optimized lookup table for accessing two types of serializers; typed and non-typed. Only accessed from a single thread, so no synchronization needed for accessors.

Fields
Modifier and Type	Field and Description
`protected SerializerCache.TypeKey`	`_cacheKey` We'll reuse key class to avoid unnecessary instantiations; since this is not shared between threads, we can just reuse single instance.
`protected JsonSerializerMap`	`_map` Actual mappings from type key to serializers

Methods
Modifier and Type	Method and Description
`static ReadOnlyClassToSerializerMap`	`from(HashMap<SerializerCache.TypeKey,JsonSerializer<Object>> src)` Factory method for creating the "blueprint" lookup map.
`ReadOnlyClassToSerializerMap`	`instance()`
`JsonSerializer<Object>`	`typedValueSerializer(Class<?> cls)`
`JsonSerializer<Object>`	`typedValueSerializer(JavaType type)`
`JsonSerializer<Object>`	`untypedValueSerializer(Class<?> cls)`
`JsonSerializer<Object>`	`untypedValueSerializer(JavaType type)`

```
public static ReadOnlyClassToSerializerMap from(HashMap<SerializerCache.TypeKey,JsonSerializer<Object>> src)
```
Factory method for creating the "blueprint" lookup map. Such map can not be used as is but just shared: to get an actual usable instance, instance() has to be called first.
