HxmType Enumeration¶
- enum Hexaly.Modeler.HxmType¶
Modeler types available in this API.
- Nil¶
Nil is the equivalent of null in C#. The single value of this type is accessed through the keyword nil in Hexaly Modeler. It is used to signify the absence of a value. Nil is the default returned value for functions that don’t explicitly return anything. It’s also the default value assigned by the modeler to every global and local variable.
- Int¶
Integers are positive and negative integral numbers stored on 64 bits. They are created by integer literals or returned as results of arithmetic operations.
- Double¶
Double precision floating point numbers (stored on 64 bits) in IEEE 754 binary floating point representation. They are created by floating point literals or returned as results of arithmetic operations.
- String¶
A string is an immutable sequence of unicode characters stored in UTF-8 format.
- Expression¶
HxExpressions are the variables and the expressions of the mathematical model defined by the modeling program or directly in the Hexaly Optimizer API.
- Function¶
Function of the modeler. The modeler treats functions as first-class citizens. In other words, a function is a value with a particular type. Thus, functions can be passed as arguments to other functions, can be assigned to variables or returned by other functions.
A function can be written using the Hexaly modeling language (user-defined function) or can be a function written in C# and exposed to the modeler.
- Map¶
Maps are data structure matching some values to some keys. This is the main data structure in the modeler that can also be used as an array-like structure.
- Module¶
A module is a collection of global variables. Modules are used to group functions together and import them dynamically at runtime. The I/O library is an example of a module. Each HXM file is a module.
- Other¶
Any other value used in the modeler but not exposed in this API (dates, files or streams for example).
