FunctionExpression class

This class defines the base class for Firestore Pipeline functions, which can be evaluated within pipeline execution.

Typically, you would not use this class or its children directly. Use either the functions like and(), equal(), or the methods on Expression (Expression.equal(), Expression.lessThan(), etc.) to construct new Function instances.
