%Library.List
datatype class %Library.List
ODBC Type: VARCHAR
The %List data type class is used to represent data that is in $List format. The logical value for %List is a list of elements in $List format.When a %List data type value is projected to a client application, it exposes it as a syslist object. This allows the client application to efficiently manipulate the contents of the list.
Note that $List
format is a compressed binary format; for this reason,
a property of type of %List cannot be set through SQL nor can its value be queried
through SQL (such as with a WHERE clause).
Refer to the documentation on $List in the ObjectScript Reference for more information.
Method Inventory
Parameters
parameter JSONTYPE = string;
JSONTYPE is JSON type used for this datatype.
parameter ODBCDELIMITER = ,;
A %List value is converted to a delimited string when
it is projected via ODBC. ODBCDELIMITER is the delimiter character
used to construct the delimited string.
parameter XSDTYPE = string;
Declares the XSD type used when projecting XML Schemas.
Methods
classmethod LogicalToOdbc(val="") as %String
Converts the value of this data type from $List format to a delimited string
using the value of the ODBCDELIMITER parameter as a delimiter.
Converts the ObjectScript $list value to the canonical SOAP encoded value.
classmethod OdbcToLogical(val="") as %String
Converts the value of an incoming delimited string to $List format
using the value of the ODBCDELIMITER parameter as a delimiter.
