Components in jBEAM
jBEAM consists of three different components: producer, consumer, and worker components. Producers create result objects without consuming data or created data objects. Consumer components use data objects but produce none. Worker components are the most complex constituents due to the fact that they produce as well as consume various objects. The Cea2Bus stores references of these objects.
The Cea2Bus stores references of these objects. 
For instance, an import is a producer, a calculation is a worker and a graphic is a consumer.
Create Components
There are two different ways to create a component. First, create a component by the componentID
import com.AMS.jBEAM.*;
int type = jbComponentIF.EXCEL_FILE_EXPORT;
boolean showDialog = false;
// the editor of the component is not displayed
try {
FileExport_Excel comp = (FileExport_Excel) jC.newComponent(type, showDialog);
} catch (ComponentException compExc) {
compExc.printStackTrace();
}
int type = jbComponentIF.EXCEL_FILE_EXPORT;
boolean showDialog = false;
// the editor of the component is not displayed
try {
FileExport_Excel comp = (FileExport_Excel) jC.newComponent(type, showDialog);
} catch (ComponentException compExc) {
compExc.printStackTrace();
}
Second, the creation is realized by means of the component description.
import com.AMS.jBEAM.*;
int excelType = jbComponentIF.EXCEL_FILE_EXPORT;
jbComponentDescriptionIF cd = jC.getComponentDescription(excelType);
if (cd.isResolved()){
try {
FileExport_Excel comp = (FileExport_Excel)jC.newComponent(cd);
} catch (ComponentException compExc) {
compExc.printStackTrace();
}
}
int excelType = jbComponentIF.EXCEL_FILE_EXPORT;
jbComponentDescriptionIF cd = jC.getComponentDescription(excelType);
if (cd.isResolved()){
try {
FileExport_Excel comp = (FileExport_Excel)jC.newComponent(cd);
} catch (ComponentException compExc) {
compExc.printStackTrace();
}
}
Delete Components
Deletes a component by name:
jC.deleteComponentByName( componentName);
