Microsoft Dynamics AX 2012 R2 - X++ Functions

In Microsoft Dynamics AX, the X++ language provides more than 100 system functions that are not part of any class. The two types of functions are as follows:

• Run time - functions that are executed during run time.

• Compile time - functions that are executed during compile time.

Run Time Functions

Run time functions used for data type conversions, mathematical operations, and so on. Some common run time functions are as follows:

• str2Int - creates an int value from a str value.

• abs - creates a positive real value from a real value that is either positive or negative.

• conFind - retrieves the location of an element in a container.

Call Run Time Functions from .NET

• The logic of the X++ run time functions is also implemented in the following .NET assembly:

Microsoft.Dynamics.AX.Xpp.Support.DLL

• Inside the previous assembly, the X++ run time functions are implemented as static methods of the following class:

Microsoft.Dynamics.AX.Xpp.PredefinedFunctions

Compile Time Functions

Compile time functions are executed early in the compile of X++ code. Most of these functions retrieve metadata about items that are in the Application Object Tree (AOT). Some common compile time functions are as follows:

• classNum - retrieves the ID of a class.

• classStr - verifies during compile time that a class by that name exists. This is better than discovering the error later during run time.

• evalBuf - evaluates the input string of X++ code, and then returns the results as a string.

• literalStr - retrieves a label ID when given the string representation of a label, such as the string "@SYS12345". For example, myLabel.exists(literalStr("@SYS12345"));.

Note: Compile time functions are sometimes called intrinsic functions.

Note: X++ compile time functions cannot be called from a .NET program.  


My above blog is based on Microsoft's Official information.

I hope this blog about 'Microsoft Dynamics AX 2012 R2 - X++ Functions' was informative. Please feel free to leave your comments.

Microsoft Dynamics AX 2012 R2 - Intrinsic Functions

Intrinsic functions are metadata assertion functions. They take arguments that represent entities in the Application Object Tree (AOT), and validate these arguments at compile time. They have no effect at run time. Intrinsic functions are a subgroup of the X++ system functions, and typically have names ending in Num or Str, for example: classNum and formStr.

Intrinsic functions should be used wherever possible in X++ code to make the code resilient to changes to the metadata stored in the AOT.

You will get a best practice warning if you use the for identifierStr function. This is because no existence checking is carried out for identifierStr. Try to use a more specific intrinsic function if one is available.

The following list contains the intrinsic functions in MorphX.

Validation of Table Metadata

• tableCollectionStr
• tableFieldGroupStr
• tablePName
• tableNum
• tableMethodStr
• tableStaticMethodStr
• tableStr

Validation of Field Metadata

• fieldNum
• fieldPname
• fieldStr

    

Validation of Index Metadata

• indexNum
• indexStr

Validation of Data Type Metadata

• enumCnt
• enumNum
• enumStr
• extendedTypeNum
• extendedTypeStr
• typeId

    

Validation of Configuration Key Metadata

• configurationKeyNum
• configurationKeyStr

Validation of License Metadata

• licenseCodeNum
• licenseCodeStr

Validation of Class Metadata

• classNum
• classStr
• methodStr
• staticMethodStr

Validation of Form, Report, Query, and Menu Metadata

Where possible, use the AutoDeclaration property on controls.

• formStr

Note: In forms, control:: controlName returns the ID of the control.

• formControlStr
• menuItemActionStr
• menuItemDisplayStr
• menuItemOutputStr
• menuStr
• reportStr
• queryStr
• queryDataSourceStr

    

Validation of Web Metadata

• webActionItemStr
• webDisplayContentItemStr
• webletItemStr
• webOutputContentItemStr
• webpageDefStr
• webReportStr
• websiteDefStr
• websiteTempStr
• webStaticFileStr
• webUrlItemStr
• webWebpartStr

Other

• identifierStr
• literalStr
• maxDate
• maxInt
• minDate
• minInt
• resourceStr
• varStr

Microsoft Dynamics AX 2012 R2 - Functions

 Most of the functions are executed when your application runs, but some are executed earlier by the compiler.

The Global Class contains a set of methods that are generally useful throughout the application. These methods can be considered an extension to the built-in functions in the X++ language. The DateTimeUtil Class also contains methods of general use for manipulating a utcdatetime value.
