ProcessDataInfo describes the structure of the process
data associated with a
de.danet.an.workflow.omgcore.WfExecutionObject WfExecutionObject .
The OMG specification defines that the data type is specified by
its "IDL type represented by its string name". Porting this to Java
is a bit difficult as the equivalent to this would be to support
something like textual representations of Java types, i.e. Java
source code.
While this issue needs further investigation, we define the
following: Java primitive types are represented by the
corresponding classes (e.g. boolean values are represented by a map
entry with value java.lang.Boolean.class). Support of
complex types depends on the workflow engine used (some may support
any [serializable] Java object as process relevant data, some may
support only XML as serialized format), as does the way process
definitions define complex types (e.g. as XML Schema
Description).
In addition to the classes representing Java primitive forms, an
implementation may therefore specify additional types to describe
the type information of a process data item.
