procedure WriteHeader(DstStream: TStream; const aPrecision: TPrecision);
Writes the header information for the calling vector to a stream.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | DstStream | Stream | |
| 2 | aPrecision | TPrecision |
Result: stored in self (calling object)
Remarks:
Writes the header information for the calling object to a DstStream stream. The header information contains information about object (size, type of values in Values array, ...) which all define the state of the object. Number type is defined by the Precision parameter. Attempt to save single precision or double precision will raise an exception.
Examples
var b: TVecInt;
AStream: TFileStream;
begin
CreateIt(b);
b.SetIt([0,0,1,3,2]);
AStream := TFileStream.Create('C:\test.bin',fmCreate);
try
b.WriteHeader(AStream); // Write info for b
b.WriteValues(AStream); // Write values of b
finally
AStream.Free;
FreeIt(b);
end;
