Description

Is there an existing issue?
Use case

It is very useful when implementing paged queries.

class Entity {
    var ids: LongArray? = null
}

fun QueryBuilder<Entity>.filter(id: Long) {
    contains(Entity_.ids, id)
}
Proposed solution
public QueryBuilder<T> contains(Property<T> property, bool value) 
public QueryBuilder<T> contains(Property<T> property, int value) 
public QueryBuilder<T> contains(Property<T> property, long value) 

OR

public PropertyQueryCondition<ENTITY> contains(bool value)
public PropertyQueryCondition<ENTITY> contains(int value)
public PropertyQueryCondition<ENTITY> contains(long value)
Alternatives

Research direction

Start with the QueryBuilder and PropertyQueryCondition entry points mentioned in the issue, then inspect existing condition methods and their tests for scalar properties. The work is done when contains supports BooleanArray, IntArray, and LongArray properties with the proposed value types and coverage verifies the query behavior.
