TVecSmallInt.Resize Method

Overload List

#	Signature	Description
1	function Resize(const Src: TVecInt; Len: Integer; ZeroIt: Boolean): TVecInt;	Resizes vector size while preserving values.
2	function Resize(Len: Integer; ZeroIt: Boolean): TVecInt;	Resizes calling vector Length to Len.

Overload 1: function Resize(const Src: TVecInt; Len: Integer; ZeroIt: Boolean): TVecInt;

Resizes vector size while preserving values.

#	Name	Type	Description
1	Src	TVecInt	source TVecInt
2	Len	Integer	element count
3	ZeroIt	Boolean

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

Remarks:

Resizes calling vector TMtxVecBase.Length to Len and fills it with Src vector first Len values. If Src length is less than Len and ZeroIt parameter is true, the remaining calling vector values are set to zero.

Examples

var a, b: TVecInt;
begin
    CreateIt(a,b);
    try
        a.SetIt([1,2,3]);
        b.SetIt([9]);
        b.Resize(a,7,True); // b=(9,1,2,3,4,0,0,0)
    finally
        FreeIt(a,b);
    end;
end;

Overload 2: function Resize(Len: Integer; ZeroIt: Boolean): TVecInt;

Resizes calling vector Length to Len.

#	Name	Type	Description
1	Len	Integer	element count
2	ZeroIt	Boolean

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

Remarks:

If TMtxVecBase.Length is less than Len and ZeroIt parameter is true, the remaining calling vector values are set to zero.

Examples

var a: Tvec;
begin
    CreateIt(a);
    try
        a.SetIt(false,[1,2,3]);
        a.Resize(7,True); // a= [1,2,3,0,0,0,0]
    finally
        FreeIt(a);
    end;
end;
