Description

The Enumeration type of the OTX DataTypes extension allows the OTX authors to define their own customized enumerations. To define the structure of the Enumeration the EnumerationSignature is used. 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.

Core Conversion

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)
