Classification
| Name | Encoding |
| Short Description | Describing different kinds of string encodings |
| Class | Simple Data Type |
| Base Data Type | - |
| Default Value | US-ASCII |
| Provide a Literal | Yes |
| SpecifiedBy | ISO 13209-3 |
| Standard Compliant | Yes |
Description
Encoding is an enumeration type describing different kinds of string encodings which shall be supported by OTX applications.
The list of allowed enumeration values is defined as follows:
| Value | Literal | Description |
| US-ASCII | @Encoding:US-ASCII | String encoding specified by [ISO/IEC 646] |
| ISO-8859-1 | @Encoding:ISO-8859-1 | String encoding specified by [ISO/IEC 8859-1] |
| UTF-8 | @Encoding:UTF-8 | String encoding from the UTF encoding family, see [ISO/IEC 10646] |
| UTF-16BE | @Encoding:UTF-16BE | String encoding from the UTF encoding family, see [ISO/IEC 10646] |
| UTF-16LE | @Encoding:UTF-16LE | String encoding from the UTF encoding family, see [ISO/IEC 10646] |
| UTF-16 | @Encoding:UTF-16 | String encoding from the UTF encoding family, see [ISO/IEC 10646] |
| BIN | @Encoding:BIN | Simple radix-based string encoding for binary-dump strings |
| OCT | @Encoding:OCT | Simple radix-based string encoding for octal-dump strings |
| HEX | @Encoding:HEX | Simple radix-based string encodingfor hexadecimal-dump strings |
Order Relation
Encoding values may occur as operands of comparisons. For this case, the following order relation is defined. Started with the lowest value US-ASCII = 0:
US-ASCII < ISO-8859-1 < UTF-8 < UTF-16BE < UTF-16LE < UTF-16 < BIN < OCT < HEXLiteral
The syntax for Literals for complex data types should be used, where the member value is one of the values in the list.
Encodings={US-ASCII|ISO-8859-1|UTF-8|UTF-16BE|UTF-16LE|UTF-16|BIN|OCT|HEX}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 index of the value in the Encodings enumeration (smallest index is 0) | Integer val = ToInteger(@Encoding:US-ASCII); // Returns 0 |
| ToFloat | Undefined (should not be used) | |
| ToString | Returns the name of the enumeration value | String s = ToString(@Encoding:US-ASCII); // Returns "US-ASCII" |
| ToByteField | Undefined (should not be used) |
Sample
Encoding MyEncodingVariable = @Encoding:US-ASCII;
