Specialized Type Handlers

Although most types in the JDK or any other Java library will work with MicroStream, there is a bunch of specialized type handlers for the most commonly used types. They are optimized to reduce memory overhead and increase performance.

The following list describes all types for which special type handlers are implemented. All other types are analyzed generically.

Value Types

Primitive Types

All primitive Types and arrays thereof

java.lang

Byte
Boolean
Short
Character
Integer
Float
Long
Double
Void
Object
String
StringBuffer
StringBuilder

java.math

BigDecimal
BigInteger

java.util

Date
Currency
Locale
OptionalInt
OptionalLong
OptionalDouble

java.util.regex

Pattern

java.io

File

java.nio.file

Path

java.net

InetAddress
Inet4Address
Inet6Address
InetSocketAddress
URI
URL

Collections

Most collections above are handled in a generic way. If you want a more optimized version of JDK collection handlers, you can utilize the provided module microstream-persistence-binary-jdk8.

pom.xml

<dependencies>
	<dependency>
		<groupId>one.microstream</groupId>
		<artifactId>microstream-persistence-binary-jdk8</artifactId>
		<version>07.01.00-MS-GA</version>
	</dependency>
</dependencies>

final EmbeddedStorageFoundation<?> foundation = EmbeddedStorage.Foundation();
foundation.onConnectionFoundation(BinaryHandlersJDK8::registerJDK8TypeHandlers);
