Detailed Description

Enumeration is an otx:SimpleType for a list of named Integer values

An Enumeration consists of a set of named constants called enumeration elements. Each enumeration element assigns a unique name to a unique IntergerLiteral, so that the name can be used as an EnumerationLiteral inside OTX instead of the integer value. The simple term of the enumerator value is its integer value. Thus, for relational terms, the integer values of the specific enumerator value are used.

Note: IMPORTANT - If the OTX Core conversion term otx:ToString is applied to an Enumeration term, the element name shall be returned. Note: IMPORTANT - If the OTX Core conversion term otx:ToInteger is applied to an Enumeration term, the Integer value shall be returned. Note: IMPORTANT - An Enumeration value can be persisted, see OTX Persistence extension.

Literal
Enumeration values are named constants. Therefore the EnumerationLiteral term will return a reference to the value of the constant that has the name provided in the EnumerationLiteral's elementName field.

EnumerationSignature1.EnumerationElement1

Conversion terms
The following table shows the rules for conversion to another data type:

Conversion	Result	Sample
ToBoolean	Undefined (should not be used)
ToInteger	Returns the integer value of the enumeration term	Integer n = ToInteger(enumerationSignatureVariable); // Returns 12 (supposed the current enumeration element's value is 12)
ToFloat	Undefined (should not be used)
ToString	Returns the name of current enumeration element	String s = ToString(enumerationSignatureVariable); // Returns "EnumerationElement1"
ToByteField	Undefined (should not be used)

Checker rules

Core.CheckerRule.Core_Chk053 – no dangling OtxLink associations
CheckerRule.DataType_Chk002 - Correct target for Enumeration

Sample

package DataType.EnumerationSignature EnumerationSignature1(Integer EnumerationElement1 = 3, Integer EnumerationElement2 = 5, Integer EnumerationElement3 = 7, Integer EnumerationElement4 = 9);
// Global Declarations
public procedure main()
{
    // Local Declarations
    EnumerationSignature1 Enumeration1 = EnumerationSignature1.EnumerationElement1;
}
