MatrixInt.Create Constructor

Overload List

#	Signature	Description
1	constructor Create(const Src: TMtxInt);	Uses TMtxInt object as internal storage.
2	constructor Create(FromObjectCache: Boolean);	Constructor of the record.
3	constructor Create(const aRows: Integer; const aCols: Integer);	Constructor of the record.
4	constructor Create(const aRows: Integer; const aCols: Integer; const aPrecision: TIntPrecision);	Internally creates TMtxInt object without using object cache.

Overload 1: constructor Create(const Src: TMtxInt);

Uses TMtxInt object as internal storage.

#	Name	Type	Description
1	Src	TMtxInt

Result: stored in self (calling object)

Remarks:

The resulting Vector will own Src object of TMtxInt type and will release it once Vector gets out of scope.

Overload 2: constructor Create(FromObjectCache: Boolean);

Constructor of the record.

#	Name	Type	Description
1	FromObjectCache	Boolean

Result: stored in self (calling object)

Remarks:

Returns a Vector with internal TMtxInt object created from object cache (CreateIt), if FromObjectCache is True. Pass false to the constructor or do not call it at all, if the variable is a local variable. Object cache has limited size.

Overload 3: constructor Create(const aRows: Integer; const aCols: Integer);

Constructor of the record.

#	Name	Type	Description
1	aRows	Integer
2	aCols	Integer

Result: stored in self (calling object)

Remarks:

Returns a Vector with internal TMtxInt object created explicitely with Length property set to aLength and IntPrecision property set to int32. Call this constructor, if the Vector type variable is a global variable with a long life span.

Examples

var a,b: MatrixInt;
    bvec: TMtxInt;
begin
    a := MatrixInt.Create(true); //create from object cache via CreateIt

    //this constructor can be omitted, because it is implicitly called
    //the first time that the variable is used.
    //However:

    b := MatrixInt.Create(10);

    //Similar to

    bvec := TMtxInt.Create;
    try
        bvec.Size(10);
    finally
        bvec.Free;  //b is freed on the exit from the procedure
    end;
end;

Overload 4: constructor Create(const aRows: Integer; const aCols: Integer; const aPrecision: TIntPrecision);

Internally creates TMtxInt object without using object cache.

#	Name	Type
1	aRows	Integer
2	aCols	Integer
3	aPrecision	TIntPrecision

Result: stored in self (calling object)

Remarks:

Creates TMtxInt object without using object cache. Suitable for declaring global variables.
