We need to add some fluent API for predicate composition using AND conjunctions. See example;

where(Address::value).isEqualTo("addressValue")
        .and(Address::zipCode).isEqualTo(123)
        .and(Address::country).notNull();

Acceptance

• Support of the predicate conjunction should be added to the predicate builder

Acceptance

• Implementation of the following common list predicates should be added (place in the same Predicates.java class):
  • isEmpty
  • notEmpty
  • hasSize
  • notHaveSize
  • contains
  • notContain
• Initial support of the following expression builder should be added:

where().list(User::roles).isEmpty();

• All object predicates from #1 should be inherited:

where().list(User::roles).isEqualTo(someList);
where().list(User::roles).isNull();
where().list(User::roles).notNull();
...

Implementation of the following common object predicates:

Object predicates

• isEqualTo
• notEqualTo
• isNull
• notNull
• isInstanceOf
• notInstanceOf
• alwaysTrue
• alwaysFalse

Add initial support of construction

where(User::id).isEqualtTo(123);

Acceptance

• Implementation of the following common boolean predicates should be added (place in the same Predicates.java class):
  • isTrue
  • notTrue
  • isFalse
  • notFalse
• Initial support of the following expression builder should be added:

where().booleanValue(User::active).isTrue();

• All object object predicates from #1 should be inherited:

where().booleanValue(User::active).isEqualTo(someBoolean);
where().booleanValue(User::active).isNull();
where().booleanValue(User::active).notNull();
