de.aristaflow.adept2.core.changeoperations.UpdateDataElement

public class UpdateDataElement
extends Object

Change Operation to update the properties of a data element. Call isPossible first to check if the update is valid, than call perform operation to execute the change. TODO Refactor; use a common interface for change operations.

Method Detail

isPossible

public static boolean isPossible(Template template,
                                 DataElement dataElement,
                                 ProcessConstants.DataElementProperty... dataElementProperties)

Tests if it is valid (concerning structural correctness) to change the data element properties given by dataElementProperties in the template. The following attributes / properties may be updated and must therefore be tested:

• NAME
• DESCRIPTION
• TYPE
• USER_DEFINED_TYPE
• IDENTIFIER
• VIRTUAL

Parameters:

template - the related template

dataElement - the data element whose properties should be changed

dataElementProperties - A constant describing the data element attribute(s) which are to be changed

Returns:

true if the change is possible

isPossible

public static boolean isPossible(Template template,
                                 DataElement dataElement,
                                 CheckReport checkReport,
                                 ProcessConstants.DataElementProperty... dataElementProperties)

Tests if it is valid (concerning structural correctness) to change the data element properties given by dataElementProperties in the template. The following attributes / properties may be updated and must therefore be tested:

• NAME

• VIRTUAL

If it is not possible the reasons are stored in the checkReport.

Parameters:

template - the related template
