TMtxSmallInt.SetVal Method

Overload List

#	Signature	Description
1	function SetVal(const Value: Integer; Row: Integer; Col: Integer; ToRow: Integer; ToCol: Integer): TMtxInt;	Initializes matrix values to Value.
2	function SetVal(Value: Integer): TMtxVecInt;	Set all calling object elements to Value.
	└ indexed: function SetVal(Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Overload 1: function SetVal(const Value: Integer; Row: Integer; Col: Integer; ToRow: Integer; ToCol: Integer): TMtxInt;

Initializes matrix values to Value.

#	Name	Type
1	Value	Integer
2	Row	Integer
3	Col	Integer
4	ToRow	Integer
5	ToCol	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Sets the calling matrix elements [Row,Col]..[ToRow,ToCol] to Value. An exception is raised if TMtxVecBase.ConditionCheck is true and array bounds are overrun.

Overload 2: function SetVal(Value: Integer): TMtxVecInt;

Set all calling object elements to Value.

#	Name	Type	Description
1	Value	Integer

Result: stored in self (calling object), returns self for chaining

Examples

Uses MtxVecInt;

procedure Example;
var a: TVecInt;
begin
    CreateIt(a);
    try
        a.SetIt([1,2,3,4]);
        a.SetVal(5,2,2); // a = [1,1,5,5]
    finally
        FreeIt(a);
    end
end;

Indexed: function SetVal(Value: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Set all calling object elements [Index]..[Index+Len-1] to Value.

#	Name	Type	Description
1	Value	Integer
2	Index	Integer	start index
3	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

An exception is raised if array borders are overrun/underrun.

Examples

var
    a: TMtxInt;
begin
MtxVecInt.CreateIt(out a);
try
a.SetIt(2,2,new int[] {1,2,3,4});
a.SetVal(5,2,2);  // a = [1,1,5,5]
finally
MtxVecInt.FreeIt(ref a);
end;
end;
