The Serializer also stores the String's size, allowing it to be used as a GroupSerializer in BTreeMaps. Neighboring strings may be delta encoded for increased storage efficency. Deserialized strings are automatically interned `String#intern()` allowing a more heap space efficient storage for repeated strings.

If a `null` value is passed to the Serializer, a NullPointerException will be thrown.
STRING_NOSIZE	`static val STRING_NOSIZE: Serializer<String>` A predefined Serializer that handles non-null String whereby Strings are serialized to a UTF-8 encoded format. The Serializer does not store the String's size, thereby preventing it from being used as a GroupSerializer. This Serializer hashes Strings using the original hash code method as opposed to the `Serializer#STRING` Serializer. If a `null` value is passed to the Serializer, a NullPointerException will be thrown.
STRING_ORIGHASH	`static val STRING_ORIGHASH: GroupSerializer<String>` A predefined Serializer that handles non-null String whereby Strings are serialized to a UTF-8 encoded format. The Serializer also stores the String's size, allowing it to be used as a GroupSerializer in BTreeMaps.

UUID	`static val UUID: GroupSerializer<UUID>` Serializers java.util.UUID class

Functions

deserialize	`open fun deserialize(in: DataInput2, available: Int): String`

serialize	`open fun serialize(out: DataOutput2, value: String): Unit`

Inherited Functions

deserializeFromLong

open fun deserializeFromLong(input: Long, available: Int): A

Deserializes and returns the content of the given long.

fixedSize

open fun fixedSize(): Int

Returns the fixed size of the serialized form in bytes or -1 if the size is not fixed (e.g. for Strings).

Some optimizations can be applied to serializers with a fixed size.
