Class StringEnumFieldValue

java.lang.Object

com.canto.cumulus.fieldvalue.StringEnumFieldValue

All Implemented Interfaces:

FieldValue

public class StringEnumFieldValue
extends java.lang.Object
implements FieldValue

A field value wrapper for a "String List" field, e.g. a field with the GUID GUID.UID_REC_STATUS or GUID.UID_REC_COLOR_MODE. Use Item.getStringEnumValue(com.canto.cumulus.GUID) to get this wrapper class object. You can then use Item.setStringEnumValue(com.canto.cumulus.GUID, StringEnumFieldValue) to set the field value back into the item. You can use the wrapper object from one item to save it to another item but both have to belong to the same catalog.
