Package com.fasterxml.jackson.databind.util

Class CompactStringObjectMap

java.lang.Object

com.fasterxml.jackson.databind.util.CompactStringObjectMap

All Implemented Interfaces:

Serializable

public final class CompactStringObjectMap
extends Object
implements Serializable

Specialized lookup class that implements functionality similar to Map, but for special case of key always being String and using more compact (and memory-access friendly) hashing scheme. Assumption is also that keys are typically intern()ed.

Generics are not used to avoid bridge methods and since these maps are not exposed as part of external API.
