The logical value of the %String data type is a string. Method Inventory DisplayToLogical() IsValid() JSONToLogical() LogicalToDisplay() LogicalToJSON() LogicalToOdbc() LogicalToXSD() Normalize() XSDToLogical() Parameters parameter COLLATION; The default collation value used for this data type. Note that if you specify a truncation length and also a VALUELIST then your truncation length must be longer or equal to your longest VALUELIST value parameter CONTENT = STRING; XML element content "MIXED" for mixed="true" and "STRING" or "ESCAPE" for mixed="false". If CONTENT="STRING" (default) XML special characters are put in a CDATA section during XML export. If CONTENT="ESCAPE" XML special characters are escaped during XML export. If CONTENT="ESCAPE-C14N" XML special characters are escaped during XML export using the translate table, XMLC, specified for XML Canonicalizaton. The main difference is that CR is escaped as &#13; parameter DISPLAYLIST; Used for enumerated (multiple-choice) attributes. Used in conjunction with the VALUELIST parameter for enumerated (multiple-choice) attributes. DISPLAYLIST, if not null, represents the display values for the attribute corresponding with the logical values listed in VALUELIST. The display values are returned by the LogicalToDisplay method. parameter ESCAPE = XML; Controls the translate table used to escape content when CONTENT="MIXED" is specified. parameter JSONLISTPARAMETER; Used to specify the name of the parameter which contains the enumeration list for JSON values. The parameter which contains the list must be in the format used for VALUELIST and DISPLAYLIST. The default is VALUELIST. parameter JSONTYPE = string; JSONTYPE is JSON type used for this datatype. parameter MAXLEN = 50; The maximum number of characters the string can contain. parameter MINLEN; The minimum number of characters the string can contain. parameter PATTERN; A pattern which the string should match. The value of PATTERN should be a valid ObjectScript pattern match expression. parameter TRUNCATE = 0; Determines whether to truncate the string to MAXLEN characters. parameter VALUELIST; Used for enumerated (multiple-choice) attributes. VALUELIST is either a null string ("") or a delimiter separated list (where the delimiter is the first character) of logical values. If a non-null value is present, then the attribute is restricted to values in the list, and the validation code simply checks to see if the value is in the list. parameter XMLLISTPARAMETER; Used to specify the name of the parameter which contains the enumeration list for XML values. The parameter which contains the list must be in the format used for VALUELIST and DISPLAYLIST. The default is VALUELIST. parameter XSDTYPE = string; Declares the XSD type used when projecting XML Schemas. Methods classmethod DisplayToLogical(%val As %String) as %String Converts the input value %val, which is a string, into the logical string format. Returns the logical value of the input string %val. classmethod IsValid(%val As %RawString) as %Status Tests if the logical value %val, which is a string, is valid. The validation is based on the class parameter settings used for the class attribute this data type is associated with. In this case, MINLEN, MAXLEN, VALUELIST, and PATTERN. classmethod JSONToLogical(%val As %String) as %String If JSONLISTPARAMETER is specified, XSDToLogical is generated which imports using the list specified by JSONLISTPARAMETER. classmethod LogicalToDisplay(%val As %String) as %String Converts the value of %val, which is in logical format, into a display string. Removes all the null characters from the string. Returns the string value of %val. classmethod LogicalToJSON(%val As %String) as %String If JSONLISTPARAMETER is specified, XSDToLogical is generated which exports using the list specified by JSONLISTPARAMETER. classmethod LogicalToOdbc(%val As %String) as %String classmethod LogicalToXSD(%val As %String) as %String If XMLLISTPARAMETER is specified, XSDToLogical is generated which exports using the list specified by XMLLISTPARAMETER. classmethod Normalize(%val As %RawString) as %String Truncates value %val to MAXLEN, characters. classmethod XSDToLogical(%val As %String) as %String If XMLLISTPARAMETER is specified, XSDToLogical is generated which imports using the list specified by XMLLISTPARAMETER.
