Value Types

Built-in

Apache Isis can render and persist all of the JDK primitives and wrapper classes, and a number of other JDK (7.x) classes that represent value types.

It also supports some of the Joda-Time datatypes, and a number of value types that are shipped by the framework itself.

In addition to primitives, the JDK Classes supported are:

  • the wrapper classes:

    • java.lang.Boolean, java.lang.Character, java.lang.Double, java.lang.Float, java.lang.Long, java.lang.Integer, java.lang.Short, java.lang.Byte

  • java.lang.String

  • numeric data types:

    • java.math.BigDecimal

    • java.math.BigInteger

  • date types:

    • java.sql.Date

    • java.sql.Time

    • java.sql.Timestamp

    • java.util.Date

Joda Time

It also supports these Joda-Time classes:

  • org.joda.time.DateTime

  • org.joda.time.LocalDateTime

  • org.joda.time.LocalDate

Framework-defined

The framework also defines a number of custom value types:

In addition, there are a number of non-core value types that can be brought in individually. These can be found in the Value Type Catalog.
