FireDAC.Phys.MongoDBWrapper.TMongoSelector.TExpression inherits from FireDAC.Phys.MongoDBWrapper.TMongoExpression. All content below this line refers to FireDAC.Phys.MongoDBWrapper.TMongoExpression.


Represents a fluent style MongoDB expression builder.

TMongoExpression is a generic base class. Please do not use it directly in your applications.

The API of this class is equivalent to the TMongoDocument API, and adds only two new methods:

  • TMongoExpression.End: Finishes this stage or operation, and returns a reference to the parent object of this expression.
  • TMongoExpression.Exp: Appends the specified field and expression to this expression, and returns a reference to this expression.
