public class DbMappingRecordField

extends DbMappingScriptNode

implements HasRecordField, HasRecordName

implementation of a record field. This is used by nodes that do convert their field descriptions to a DbMappingRecordFieldList. The presented implementation allows to store all information out of some SELECT subclause in the smacs input syntax. The implementation has been overloaded over time and should be refactored into making this type an interface with more specific implementation classes taylored for the usage in the nodes having a list of record fields. There is no hard need to do so since this implementation node has the HasRecordField and HasRecordName interface which can be used in other stages to access any record field information by means of an interface layer.
