4.1.1 Supported Data Types

All open MBean attributes, method return values, and method arguments must be limited to the set of open MBean data types listed in this section. This set is defined as: the wrapper objects that correspond to the Java primitive types (such as Integer, Long, Boolean), String, CompositeData, TabularData, and ObjectName.

In addition, any array of the open MBean data types may be used in open MBeans. A special class, javax.management.openmbean.ArrayType is used to represent the definition of single or multi-dimensional arrays in open MBeans.

The following list specifies all data types that are allowed as scalars or as any-dimensional arrays in open MBeans:

• java.lang.Boolean

• java.lang.Byte

• java.lang.Character

• java.lang.Short

• java.lang.Integer

• java.lang.Long

• java.lang.Float

• java.lang.Double

• java.lang.String

• java.math.BigInteger

• java.math.BigDecimal

• javax.management.ObjectName

• javax.management.openmbean.CompositeData (interface)

• javax.management.openmbean.TabularData (interface)

In addition the java.lang.Void type may be used, but only as the return type of an operation.
