Method keywords deprecated, externalprocname, final, forcegenerate

Chapter 61 Method keyword - Deprecated

Specify that this method is not recommended . This keyword is ignored by the class compiler , It just provides a human readable indicator , Indicates that the method has been deprecated .

usage

To specify that this method is not recommended , Please use the following syntax :

Chapter 62 Method keyword - ExternalProcName

When this method is used as a stored procedure in an external database , Specify its name . Applicable only if the method is projected as a stored procedure .

To override the default name of a method when it is used as a stored procedure in an external database , Please use the following syntax :

ClassMethod name(formal_spec) As returnclass [ SqlProc, ExternalProcName = MyProcedure ] 
{    //implementation }

Copy

among MyProcedure Is a string without quotation marks .

Chapter 63 Method keyword - Final

usage

To specify that the method is final , Please use the following syntax :

Method name(formal_spec) As returnclass [ Final ]

Method name(formal_spec) As returnclass [ CodeMode = ObjectGenerator, ForceGenerate ] 
{    //implementation }

Copy

otherwise , Omit this keyword or put the word Not Put in front of the keyword .

Detailed explanation

In the case of a method generator method , Specify that the method should be compiled in each subclass . When you need to ensure that each subclass has its own method version , This keyword is very useful . If the generated code looks the same as the code generated by the superclass , IRIS Methods in subclasses will not be recompiled . This logic does not consider whether the included files of the two classes are the same . If the method uses macros defined in the include file , And if subclasses use different include files , IRIS The method will not be recompiled in subclasses . under these circumstances , Please specify ForceGenerate.

Default

If you omit this keyword , The method will not be compiled in each subclass .
