hmX_Get Variables ( Context ; Stack_id ; Typelocalglobal ; Copy) → List
Introduced in v19.0, Preemptive: yes
| Parameter | Type | In/Out | Description |
|---|---|---|---|
| Context | Longint | → | Execution context |
| Stack_id | Longint | → | stack id or 0 |
| Typelocalglobal | Longint | → | 1=local 2=global 3=inter process variable |
| Copy | Longint | → | 1=Returns a copy for Objects/Collections 0=Returns a reference for Objects/Collections |
| List | Collection | ← | Collection with all variables |
Description
The command hmX_Get Variables returns a collection of all variables of the execution context. Each collection element contains an object with the following information:
- “type”: type of the variable
- “name”: variable name
- “index”: number of the variable in the list (Start with 1)
- “value”: value of the variable (Variant, depends of the type of the variable)
Example
The following example creates an execution context and get its variables:
var $vl_context : Integer
var $vc_variables : Collection
$vl_context:=hmX_Create Execution Context
hmX_SET VARIABLE($vl_context; "myVarname"; Is longint; ""; 123; !00-00-00!)
$vc_variables:=hmX_Get Variables($vl_context; 0; 2; 1)
hmX_DELETE EXECUTION CONTEXT($vl_context)
Result:
[{type:9,name:myVarname,index:1,value:123}]
