function ReadHeader(const SrcStream: TStream): TPrecision;
Reads the header information from a stream to object.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | SrcStream | Stream |
Returns: TPrecision
Remarks:
Reads the header information from a DstStream stream to calling object. The header information contains all necessary information defining the object. The function returns the precision in which the data was stored. This information is required for the VectorInt.ReadValues method.
Examples
var b: TVecInt;
AStream: TFileStream;
Precision: TPrecision;
begin
CreateIt(b);
AStream := TFileStream.Create('C:\test.bin',fmOpenRead);
try
Precision := b.ReadHeader(AStream); // Read info for b
b.ReadValues(AStream,Precision); // Read values of b
finally
AStream.Free;
FreeIt(b);
end;
end;
