5.8.2 Encoding Rules for different kinds of DataTypes

portion the DataType BrowseName . For this reason, the BrowseName for all DataTypes should be Strings that start with a letter and contain only letters, digits or the underscore
OPC-10000-4 – OPC Unified Architecture - Part 4: Services

7.7.3 FilterOperator

null and empty arrays of the same DataType as equal. This also applies to Strings and ByteStrings . Table 119 defines complex operators that require a target node ... formatting the bytes as a sequence of hexadecimal digits. LocalizedText values are converted to Strings by dropping the Locale . Strings are converted to LocalizedText values by setting the Locale

5.1.9 Variant

same as a null value for data types that support nulls such as Strings . Some DevelopmentPlatform s may not be able to preserve the distinction between a null ... meaning when returned in a response message with an associated StatusCode and table of strings. As a result, Variants cannot contain instances of DiagnosticInfo. Values of Attributes are always returned

5.1.11 Null, Empty and Zero-Length Arrays

Arrays The terms null, empty and zero-length are used to describe array values ( Strings are arrays of characters and ByteStrings are arrays of Bytes for purposes of this discussion

5.2.2.4 String

encoded as Int32 . A value of -1 is used to indicate a 'null' string. Strings with embedded nulls (U+0000) can lead to unpredictable application behaviour because embedded nulls have ... recommended and ByteString should be used instead. That said, Encoders can encode Strings with embedded nulls. Decoders shall use the length to read all bytes in String . Figure 4 illustrates

5.3.1.5 String

String A String value is encoded as an xs:string value. Strings with embedded nulls (U+0000) are not guaranteed to be interoperable because not all DevelopmentPlatforms can handle Strings ... with embedded nulls. For this reason, embedded nulls are not recommended. Encoders may encode Strings with embedded nulls. Decoders shall read all bytes in String ; however, decoders may truncate

5.4.2.5 String

String String values shall be encoded as JSON strings. Any characters which are not allowed in JSON strings are escaped using the rules defined in IETF RFC 8259 . Strings with ... nulls ('\u0000') are not guaranteed to be interoperable because not all DevelopmentPlatforms can handle Strings with embedded nulls. For this reason, embedded nulls are not recommended. Encoders may encode Strings
