Logical Functoids

  • Artikkeli

Overview

Logical functoids are used to perform the following types of operations:

  • Perform specific logical tests at run time. The Logical OR, Logical NOT and Logical AND functoids can be used to determine whether a record is created in a destination instance message, such as the following:

    If ShipTo OR OrderedBy are present, create BillTo address record.

    You can also use these functoids in conjunction with the Looping functoid to configure how many times a record loops.

  • Control whether a specific record is created in a destination instance message at run time. Functoids such as IsNil, Logical Numeric, Less Than, and Greater Than can be used to control whether a record is created.

    If the result of one of these logical functoids is True, the corresponding record in the destination instance message is generated. If the result is False, the corresponding record in the destination instance message is not generated.

    The functoids IsNil, Logical Date, Logical Existence, Logical NOT, Logical Numeric, and Logical String accept only one parameter. The functoids Equal, Greater Than, Greater Than or Equal To, Less Than, Less Than or Equal To, and Not Equal accept two input parameters. Whereas, the Logical AND and Logical OR functoids accept input parameters between 2 and 100.

    The output of a Logical functoid can also be accepted as input to other functoids in a map. If both a Logical functoid and a looping functoid are linked together, and then linked to a record in the destination schema, the looping functoid is used only when the Logical functoid output is True.

    You can also use Logical functoids with the Value Mapping or Value Mapping (Flattening) functoids to control whether a record in the destination instance message is created.

Important

If you link two records or fields in the source schema to two different Logical functoids, and then link each of the Logical functoids to the same record in the destination schema, only the first Logical functoid is used in the generated Extensible Stylesheet Language Transformations (XSLT). The second link, from the second Logical functoid, is ignored.

Note

Logical functoids are case-sensitive when comparing two strings. For example, "Abc" and "abc" are not equal. The exception to this rule is when Logical functoids compare strings that represent the Boolean values True and False. For example, "True" and "true" are equal.

Available functoids

The Logical functoids are:

  • Equal
  • Greater Than
  • Greater Than or Equal To
  • IsNil
  • Less Than
  • Less Than or Equal To
  • Logical AND
  • Logical Date
  • Logical Existence
  • Logical NOT
  • Logical Numeric
  • Logical OR
  • Logical String
  • Not Equal

More details on these functions are in the UI guidance and developers API namespace reference.
