In this post under Lombok, I will explain with example the purpose of “cacheStrategy” attribute of “@EqualsAndHashCode” annotation. Just for recap, the annotation “@EqualsAndHashCode” when annotated to a POJO class, it generates “equals” and “hashCode” methods. Whenever the “hashCode” method of a POJO class is called, the hash is computed. To avoid computing of hashCode…… Continue reading Using @EqualsAndHashCode cacheStrategy example

Using @EqualsAndHashCode doNotUseGetters attribute example
In this post under Lombok, I will explain with example the purpose of “doNotUseGetters” attribute of “@EqualsAndHashCode” annotation. In a POJO class, we usually have getter method to return a formatted value of the actual value.

In my previous post under “Using @EqualsAndHashCode annotation”, I explained with example the purpose of that annotation. Just for recap when this annotation is applied at class level it will automatically generates “equals” and “hashCode” methods…… Continue reading Using @EqualsAndHashCode callSuper attribute
Using @EqualsAndHashCode.Include annotation
In this post under lombok. I will explain the purpose and how to use “@EqualsAndHashCode.Include” annotation. In previous post “Using @EqualsAndHashCode.Exclude” I introduced you to “@EqualsAndHashCode.Exclude” annotation. Using “@EqualsAndHashCode.Exclude” annotation we are telling Lombok which fields should not be considered when generating “equals” and “hashCode” method of a POJO class. Now “@EqualsAndHashCode.Include” is reverse of…… Continue reading Using @EqualsAndHashCode.Include annotation
Using @EqualsAndHashCode.Exclude annotation
In this post under lombok, I will show with example the purpose of @EqualsAndHashCode.Exclude annotation. In the previous post, I explained with example the purpose of “@EqualsAndHashCode” annotation. It generates “equals” and “hashCode” method for the “@EqualsAndHashCode” annotated class. When generating “equals” and “hashCode” method it takes into consideration all the fields of the class.…… Continue reading Using @EqualsAndHashCode.Exclude annotation
Using @EqualsAndHashCode annotation
In this post under Lombok, I will explain with example the purpose and how to use “EqualsAndHashCode” annotation. This annotation is applied at the class level only.
