A value type is like a structure, but with support for additional object-oriented features such as inheritance. It is similar to what is sometimes referred to in Java as a POJO—a Plain Old Java Object.
Readers familiar with value types in the context of CORBA should consult Table 4 to see which value type-related IDL keywords are supported and what their behavior is in the context of Connext DDS.
