Description
Represents the result set cursor interface.
The IMongoCursor interface is implemented by:
- The "fluent" style command builders where a command returns a result set. Therefore casting a builder to the interface executes the command and provides a cursor.
- The TMongoCursor.TDefault class, which is the default interface implementation.
Examples
To clarify, consider the following examples:
Delphi:
var
FCon: TMongoConnection;
oCrs: IMongoCursor;
Memo1: TMemo;
// ...
// Find, retrieve and show all documents from the database 'test' (collection 'restaurants')
oCrs := FCon['test']['restaurants'].Find();
while oCrs.Next do
Memo1.Text := Memo1.Text + sLineBreak + oCrs.Doc.AsJSON;
C++Builder:
TMongoConnection *FCon;
di_IMongoCursor oCrs;
Memo1* TMemo;
// ...
// Find, retrieve and show all documents from the database 'test' (collection 'restaurants')
oCrs = interface_cast<IMongoCursor>(MongoCon->Databases["test"]->Collections["restaurants"]->Find());
while (oCrs->Next()) {
Memo1->Text = Memo1->Text + sLineBreak + oCrs->Doc->AsJSON;
}
