Method Detail

setReportService

protected void setReportService(ReportService reportService)

Called by the framework to set the ReportService.

Parameters:

reportService - The ReportService

prepareDomainObject

public void prepareDomainObject(VDomainModelReference domainModelReference,
                                org.eclipse.emf.ecore.EObject domainObject)
                         throws EMFFormsExpandingFailedException

Prepares a domain object for the given VDomainModelReference. Thereby, the path defined by the VDomainModelReference is analyzed and missing objects in the domain model are created. Thereby, the VDomainModelReference is not changed.

Example:
DMR: A -> B -> x
domain model is instance of A but does not reference an instance of B
=> An instance of B is created and referenced by the domain model.

Specified by:

prepareDomainObject in interface EMFFormsDMRExpander

Parameters:

domainModelReference - The VDomainModelReference for which the domain object should be prepared.

domainObject - The domain object to prepare.

Throws:

EMFFormsExpandingFailedException - if the domain expansion fails.

EMFFormsDMRExpander.prepareDomainObject(org.eclipse.emf.ecp.view.spi.model.VDomainModelReference, org.eclipse.emf.ecore.EObject)

isApplicable

public double isApplicable(VDomainModelReference domainModelReference)

Returns how suitable this EMFFormsDMRExpander is for the given VDomainModelReference.

Specified by:

isApplicable in interface EMFFormsDMRExpander

Parameters:

domainModelReference - The VDomainModelReference for which a domain object should be prepared.

Returns:

a value indicating how suitable this EMFFormsDMRExpander is to expand a domain object for the given VDomainModelReference. Returns NOT_APPLICABLE if it's not applicable.
