In software engineering, a fluent interface is an object-oriented API whose design relies extensively on method chaining. Its goal is to increase code legibility by creating a domain-specific language (DSL). The term was coined in 2005 by Eric Evans and Martin Fowler. [1]
This condition makes no sense if situations were states, as two different actions executed in two different states can result in the same state. In the example robot world, if the robot's first action is to move to location ( 2 , 3 ) {\displaystyle (2,3)} , the first action is m o v e ( 2 , 3 ) {\displaystyle move(2,3)} and the resulting ...

The following code contains two assertions, x > 0 and x > 1, and they are indeed true at the indicated points during execution: x = 1 ; assert x > 0 ; x ++ ; assert x > 1 ; Programmers can use assertions to help specify programs and to reason about program correctness.
In computer software testing, a test assertion is an expression which encapsulates some testable logic specified about a target under test. The expression is formally presented as an assertion, along with some form of identifier, to help testers and engineers ensure that tests of the target relate properly and clearly to the corresponding specified statements about the target.
The fluent calculus is a formalism for expressing dynamical domains in first-order logic. It is a variant of the situation calculus; the main difference is that situations are considered representations of states. A binary function symbol is used to concatenate the terms that represent facts that hold in a situation.
The fluent realizes the common sense grounding between the robot's motion and the task description in natural language. [2] From a technical perspective, a fluent is equal to a parameter that is parsed by the naive physics engine. The parser converts between natural language fluents and numerical values measured by sensors. [3]
Even though object-oriented seems like a superset of object-based, they are used as mutually exclusive alternatives, rather than overlapping. [ citation needed ] Examples of strictly object-based languages – supporting an object feature but not inheritance or subtyping – are early versions of Ada , [ 2 ] Visual Basic 6 (VB6), and Fortran 90 .
