Dynamic Array

SetArrayLength(Cache, ArrayIn.Length);
Cache[i] := ArrayIn.asArray(i) * 0.5;

SetArrayLength

procedure SetArrayLength(var A: dynamic-array; NewLength: Integer);

Resizes a dynamic array declared in script code.

var ArrayIn   : TParameter;
var Cache     : array of single;  // dynamic buffer used to store the scaled values
var ElemCount : integer;
var i         : integer;

PROCEDURE Init;
BEGIN
  ArrayIn  := CreateParam('Array In', PtArray, pioInput);
  ArrayIn.Length(1);              
  SetArrayLength(Cache, 0);                    // initialize the dynamic buffer with zero items
END;

PROCEDURE Callback(N: integer);
BEGIN
  IF (N = ArrayIn) THEN BEGIN
    ElemCount := ArrayIn.Length;               // read how many values are provided by the upstream module
    SetArrayLength(Cache, ElemCount);          // resize the dynamic buffer so it always fits the input array
    FOR i := 0 TO ElemCount - 1 DO BEGIN
      Cache[i] := ArrayIn.asArray(i); // simple processing: copy
    END;    
    Trace(GetArrayLength(Cache)); // traces the size of the dynamic array
  END;
END;

PROCEDURE Destroy;
BEGIN
  SetArrayLength(Cache, 0);
END;

GetArrayLength

function GetArrayLength(A: dynamic-array): Integer;

Returns the size of a dynamic array declared in script code.
