Last Updated: August 21, Template method design pattern is widely accepted behavioral design pattern to enforce some sort of algorithm fixed set of steps in the context of programming. Design patterns are used to solve the problems which occur in a pattern, we all know that, right?
Also we know that behavioral design patterns …. Last Updated: August 19, The Chain of Responsibility is known as a behavioral pattern. The main objective of this pattern is that it avoids coupling the sender of the ….

There, a component's parent can act as its successor. Command and Memento act as magic tokens to be passed around and invoked at a later time.
In Command , the token represents a request; in Memento , it represents the internal state of an object at a particular time. Polymorphism is important to Command , but not to Memento because its interface is so narrow that a memento can only be passed as a value. Command can use Memento to maintain the state required for an undo operation.
Macro Command s can be implemented with Composite. A Command that must be copied before being placed on a history list acts as a Prototype. Interpreter can use State to define parsing contexts. The abstract syntax tree of Interpreter is a Composite therefore Iterator and Visitor are also applicable. Terminal symbols within Interpreter 's abstract syntax tree can be shared with Flyweight. Iterator can traverse a Composite. Visitor can apply an operation over a Composite.
Bottom line, then, a pattern is behavior that we return to time after time, that we do without necessarily thinking about. It may come as a shock to realize that something you thought was good for you is actually just the opposite. On the one hand, you know what you thought was good was possibly something that you conned yourself into believing.
Blind adherence to any idea is never wise. It takes careful thought beforehand and rigorous analysis afterward to be able to determine if a pattern of behavior is right for you.
Consider making a list of current behaviors that constitute a pattern. It helps to take notes that to use later as reference. Make two separate sheets, one each for good and bad behavior patterns. Or, simply list the behaviors and see if they fall into patterns. Then, assign them either a positive or negative value. What this value means is not whether or not you like the behavior. You liked getting high, correct? No, here the positive or negative value refers to whether it enhances or detracts from your life.
An example of a pattern of toxic behavior is taking on too much at work. As a result, stress levels increase, tension builds and productivity wanes. Working harder and longer becomes less satisfying.
