Mapping Integration Server Data Types to IDL

The signature of an Integration Server service specifies the data types for the parameters of the service. There are three data types: String, Record and Object. Parameters of type String are mapped to an IDL alphanumeric data type, parameters of type Record to IDL groups. The mapping of parameters of type Object has been enhanced in recent versions of the EntireX Adapter. For details see table below.

Parameters of type String may have an associated context type which is specified in the constraints of the parameter's properties. This content type may influence the data type mapping. The following table shows the mapping.

Integration Server Content Type	Software AG IDL Data Type
`boolean`	`L`	Logical
`decimal`	`Nx`, `Nx.y` or `An`, `AV`, `AVn`	Unpacked decimal or Alphanumeric ⁽⁵⁾
`float`	`F4`	Floating point (small)
`double`	`F8`	Floating point (large)
`Date`	`An`, `AV`, `AVn`	Alphanumeric ⁽¹⁾
`dateTime`	`An`, `AV`, `AVn`	Alphanumeric ⁽¹⁾
`base64Binary`	`An`, `AV`, `AVn`	Alphanumeric ⁽¹⁾
`byte`	`I1`	Integer (small)
`unsignedByte`	`NU3`	Unpacked decimal unsigned
`short`	`I2`	Integer (medium)
`unsignedShort`	`NU5`	Unpacked decimal unsigned
`int`	`I4`	Integer (large)
`unsignedInt`	`NU10`	Unpacked decimal unsigned
`long`	`N19`	Unpacked decimal
`unsignedLong`	`NU20`	Unpacked decimal unsigned
`integer`	`N29`	Unpacked decimal
`positiveInteger`	`NU29`	Unpacked decimal unsigned
`nonPositiveInteger`	`N29`	Unpacked decimal
`negativeInteger`	`N29`	Unpacked decimal
`nonNegativeInteger`	`NU29`	Unpacked decimal unsigned
`string`	`An`, `AV`, `AVn`	Alphanumeric ⁽²⁾
`all others`	`An`, `AV`, `AVn`	Alphanumeric ⁽¹⁾

Notes:

All parameters of type String are mapped to an IDL alphanumeric data type, available as variable (AV, AVn) or fixed (An) length. Which alphanumeric type is used is specified in the wizard page of the IDL Extractor for Integration Server or as a parameter of the generation service.
If the content type specifies a length len, then Alen is used. If the content type specifies a maximum length max, then AVmax or Amax is used, see ⁽¹⁾ for the choice between A versus Av. If neither length nor maximum length is specified, the choice is the same as in ⁽¹⁾.
If an input parameter of a service has a default value, this value is shown in the extracted IDL file as a comment. When the Adapter Listener calls this service and no value (or only a value with blanks) is specified by the RPC client, the default value is used as the parameter value.
A parameter of an EntireX Adapter service of type Object is mapped to an IDL binary data type. Depending on the target language, it is either mapped to BV (for Natural and Other) or to BV256 (for COBOL and PL/I).
If the content type specifies a total number of digits and a number of fraction digits, then Nx.y is used. If only a total number of digits is specified, then Nx is used. If no total number of digits is specified, or the total number exceeds the maximum allowed value, or the number of fraction digits exceeds the maximum allowed value, then a string according to ⁽¹⁾ is used. The maximum allowed value for the total number of digits is 29, for COBOL it is 31. The maximum allowed value for the number of fraction digits is 7, for COBOL it is 31 and for Natural it is 29.
