TypeDefinition

Attribute, function, action or parameter datatype.

Syntax:

( Identity | Alpha | Text | Boolean [ (TrueValue ,FalseValue )] | Binary [ (MimeType )] | Integer | Number [ (Precision [ ,Scale ] )] | Date | Time | Timestamp [ (Precision )] | LongText [ (MimeType )] | Stream [ (MimeType )] | GUID | Structure (StructureRef )| Entity (EntityRef )| Enumeration (EnumerationRef [ .EnumerationSubset ] )| Lookup (EnumerationRef )| List <( Identity | Alpha | Text | Boolean [ (TrueValue ,FalseValue )] | Integer | Number [ (Precision [ ,Scale ] )] | Date | Time | Timestamp | GUID | Structure (StructureRef )| Entity (EntityRef )| Enumeration (EnumerationRef [ .EnumerationSubset ] )| Lookup (EnumerationRef )) >)

Primitive datatypes, typically set on attributes, specifies the type for a single value. For example: 


         attribute Name Text {
            maxlength = 50;
         }
         attribute RunwayLength Integer;
         attribute Temperaure Number(4,2);
         attribute NextMaintanance Date;

Enumerations are specified by their underlying type, as defined in as enumeration model. For example: 


         attribute TransportedAs Enumeration(DeliveryType);

Record Structures are specified by the structure name. For example: 


         function Me Entity(Person);

Entities are specified by their underlying type, as defined in the corresponding entity model. For example: 


         function Me Entity(Person);

All of the above datatypes can also be passed as arrays. For example: 


         function Friends List<Entity(Person)>;

or 


         attribute TransportOptions List<Enumeration(DeliveryType)>;

Attributes can also be of a complex type, such as Currency or Measure.

Note:   Default type is Text with unlimited number of characters, unless maxlength is specified.
