Introduction

The xreflect module allows a package to programatically access Mosel entities whose names and types were not known at compile-time. For example, this allows a developer to write a function to increment each value in a named array by 1, regardless of the type or index sets of the array.

Limitations

xreflect can only operate on entities of the following types:

• boolean
• integer
• real
• string
• set of boolean
• set of integer
• set of real
• set of string
• array of boolean
• array of integer
• array of real
• array of string

Additionally, xreflect can only access entities declared as public, for example in a public declarations block.:

public declarations
  myArray: array(range) of string
end-declarations

Namespace

All types and subroutines exported by the xreflect module are part of the xreflect namespace; your model or package will need to reference this namespace in order to use this functionality. For example:

model myModel
 uses 'xreflect'
 nssearch xreflect

 public declarations
   myArray: array(range) of string
 end-declarations

 writeln('Type of values in myArray: ',getvaluetype('myArray'))

end-model
