ArraySort (Function) In french: TableauTrie Sorts a WLanguage array. The following sorts can be performed: - Sort a one-dimensional array of simple elements.
- Sort a two-dimensional array of simple elements according to one or more columns.
- Sort a one-dimensional array of classes or structures according to 1 or more members.
  Sort an array of records according to 1 or more items. - Sort a one-dimensional array by specifying a comparison procedure.
Note: This function is equivalent to Sort.
MyArray is array of 2 int
MyArray[1] = 4
MyArray[2] = 1
ArraySort(MyArray, asAscending)
Trace(MyArray[1], MyArray[2])
ArraySort(MyArray, asAscending, 2)
ArraySort(MyArray, asColumn, "2;-3")
ArraySort(MyArray, asFunction, Compare)
INTERNAL PROCEDURE Compare(Element1, Element2)
IF Element1.Member < Element2.Member THEN RETURN -1
IF Element1.Member > Element2.Member THEN RETURN 1
RETURN 0
Syntax
Sorting a one-dimensional array of simple elements Hide the details
ArraySort(<WLanguage array> [, <Type of sort>])
<WLanguage array>: Array - Name of the Array variable to use. This array must be a one-dimensional array.
This array can also correspond to an array of simple elements of an advanced variable ("Group" array in the gglContact variables for example). - Name of the Associative Array variable to use.
   The associative arrays cannot be sorted in this version.
<Type of sort>: Optional integer constant Type of sort to perform: | | asAscending
(Default value) | Ascending sort.Case of an associative array: Sorting the elements of the associative array:- if the constant ttClé is specified: keys are sorted in ascending order. In case of equality between two keys, the values are sorted according to the ascending value if the values can be compared. If the values cannot be compared, the initial order is kept.
- if the constant ttKey is not specified Sorting is performed in ascending order of values. In case of equality between two values, the values are sorted according to the ascending key.
| | asDescending | Descending sort.Case of an associative array: Sorting the elements of the associative array:- if the constant ttClé is specified: keys are sorted in descending order. In case of equality between two keys, the values are sorted according to the descending value if the values can be compared. If the values cannot be compared, the initial order is kept.
- if the constant ttKey is not specified Sorting is performed in descending order of values. In case of equality between two values, the values are sorted according to the descending key.
|
The sort type can be combined with one or more sort options: | | | asKey | Associative array sorted according to the key order. If this constant is not specified, the associative array is sorted according to the order of values.
This function is useful on the associative arrays only. | | tccIgnoreAccent | Array sorted while ignoring the accented characters.
This option is useful for arrays of strings.
| | tccIgnoreCase | Array sorted while ignoring the case.
This option is useful for arrays of strings. | | tccIgnoreInsideSpace | Array sorted while ignoring the space characters found inside the strings.

- "-" for a descending sort.
- "." or ":" to perform a sort on chained properties.
For example:
- "Member1;-Member3" to perform an ascending sort on the Member1 member and a descending sort on the Member3 member.

Sorting a one-dimensional array with a sort procedure Hide the details
ArraySort(<WLanguage array> , <asFunction> , <WLanguage sorting procedure>)
<WLanguage array>: Array - Name of the Array variable to use. This array must be a one-dimensional array. This array can be an array of advanced types.
- Name of the Associative Array variable to use.
The associative arrays cannot be sorted in this version.
<asFunction>: Constant ttFunction: Constant used to sort a one-dimensional array using a sorting procedure. <WLanguage sorting procedure>: Procedure name Name of the procedure used to sort the array elements. - Case of a one-dimensional array: WLanguage procedure of the form:
PROCEDURE MyProcedure(Element1, Element2)
This procedure is automatically called by the sort mechanism to compare the elements between themselves, two by two.
If the element 1 must be found before the element 2 in the sort order, the procedure must return -1.
If the element 1 must be found after the element 2 in the sort order, the procedure must return 1.
If element 1 and element 2 are identical, the procedure must return 0. - Case of an associative array: WLanguage procedure of the form:
PROCEDURE MyProcedure(Value1, Key1, Value2, Key2)
This procedure is automatically called by the sort mechanism to compare the elements between themselves, two by two. The comparison can be performed in the sort procedure according to the values or according to the keys.
If the element 1 must be found before the element 2 in the sort order, the procedure must return -1.
If the element 1 must be found after the element 2 in the sort order, the procedure must return 1.
If element 1 and element 2 are identical, the procedure must return 0.
Remarks Examples of custom sorting procedures Example of procedure used to compare 2 integers: PROCEDURE MyProcedure(nInt1, nInt2)
IF nInt1 > nInt2 THEN RETURN 1
IF nInt1 < nInt2 THEN RETURN -1
RETURN 0
Example of a procedure used to compare two elements in an array of structures: PROCEDURE MyProcedure(stVar1, stVar2)
IF stVar1:nInt > stVar2:nInt THEN RETURN 1
IF stVar1:nInt < stVar2:nInt THEN RETURN -1
RETURN 0
