Attribute type to Java object type mapping

Edit online

Attribute types are used when query tables are defined in Business Process Choreographer, when queries are run on the query tables, and when values of a query result are accessed. Use this topic for information on attribute type to Java™ object type mapping.

The following table describes the attribute types and their mapping to Java object types in query result sets.
Table 1. Attribute type to Java object type mapping
Attribute type Related Java object type
ID com.ibm.bpe.api.OID
STRING java.lang.String
NUMBER java.lang.Long
TIMESTAMP java.util.Calendar
DECIMAL java.lang.Double
BOOLEAN java.lang.Boolean

Example

…
// the following example shows a query against a composite query table
// COMP.TA; attribute "STATE" is of attribute type NUMBER
…
// run the query
// the business flow manager Enterprise JavaBeans or the
// human task manager Enterprise JavaBeans can be used to access query tables
EntityResultSet rs = bfm.queryEntities("COMP.TA",null,null,params);

// get the entities and iterate over it
List entities = rs.getEntities();
for (int i = 0 ; i < entities.size(); i++) {

      // work on a particular entity
      Entity en = (Entity) entities.get(i);
      
      // note that the following code could be written
      // more generalized using the attribute info objects
      // contained in ei.getAttributeInfo()

      // get attribute STATE
      Long state = (Long) en.getAttributeValue("STATE");
      …
}
