SerializedString (Jackson-core 2.2.0 API)
Date: 2013-04-22

## Class SerializedString

- java.lang.Object
- - com.fasterxml.jackson.core.io.SerializedString

- All Implemented Interfaces:
    SerializableString, Serializable

      public class SerializedString
      extends Object
      implements SerializableString, Serializable

  String token that can lazily serialize String contained and then reuse that serialization later on. This is similar to JDBC prepared statements, for example, in that instances should only be created when they are used more than use; prime candidates are various serializers.

  Class is final for performance reasons and since this is not designed to be extensible or customizable (customizations would occur in calling code)

    Serialized Form

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `protected String` | `_jdkSerializeValue` Ugly hack, to work through the requirement that _value is indeed final, and that JDK serialization won't call ctor(s).
    `protected char[]` | `_quotedChars`
    `protected byte[]` | `_quotedUTF8Ref`
    `protected byte[]` | `_unquotedUTF8Ref`
    `protected String` | `_value`
