Query Building & Filters

Name: tessl/maven-org-mongodb--mongo-java-driver
Author: tessl

Comprehensive query building utilities for creating MongoDB queries, filters, sorts, projections, and updates with type safety and fluent APIs.

Capabilities

Filters Utility Class

Factory methods for creating query filters with type-safe field matching.

public final class Filters {
    // Equality operations
    public static Bson eq(String fieldName, Object value);
    public static Bson ne(String fieldName, Object value);
    
    // Comparison operations
    public static Bson gt(String fieldName, Object value);
    public static Bson gte(String fieldName, Object value);
    public static Bson lt(String fieldName, Object value);
    public static Bson lte(String fieldName, Object value);
    
    // Array operations
    public static Bson in(String fieldName, Object... values);
    public static Bson nin(String fieldName, Object... values);
    
    // Logical operations
    public static Bson and(Bson... filters);
    public static Bson or(Bson... filters);
    public static Bson not(Bson filter);
    public static Bson nor(Bson... filters);
    
    // Pattern matching
    public static Bson regex(String fieldName, String pattern);
    public static Bson regex(String fieldName, Pattern pattern);
    
    // Field existence
    public static Bson exists(String fieldName);
    public static Bson exists(String fieldName, boolean exists);
    
    // Type checking
    public static Bson type(String fieldName, BsonType type);
    public static Bson type(String fieldName, String type);
}

Updates Utility Class

Factory methods for creating update operations with type safety.

public final class Updates {
    // Field updates
    public static Bson set(String fieldName, Object value);
    public static Bson unset(String fieldName);
    public static Bson rename(String fieldName, String newFieldName);
    public static Bson setOnInsert(String fieldName, Object value);
    
    // Numeric updates
    public static Bson inc(String fieldName, Number amount);
    public static Bson mul(String fieldName, Number amount);
    public static Bson min(String fieldName, Object value);
    public static Bson max(String fieldName, Object value);
    
    // Array updates
    public static Bson push(String fieldName, Object value);
    public static Bson pushEach(String fieldName, List<?> values);
    public static Bson pull(String fieldName, Object value);
    public static Bson pullAll(String fieldName, List<?> values);
    public static Bson addToSet(String fieldName, Object value);
    public static Bson popFirst(String fieldName);
    public static Bson popLast(String fieldName);
    
    // Combined updates
    public static Bson combine(Bson... updates);
}

Projections Utility Class

Factory methods for creating field projections.

public final class Projections {
    public static Bson include(String... fieldNames);
    public static Bson exclude(String... fieldNames);
    public static Bson excludeId();
    public static Bson elemMatch(String fieldName, Bson filter);
    public static Bson slice(String fieldName, int limit);
    public static Bson slice(String fieldName, int skip, int limit);
    public static Bson textScore(String fieldName);
    public static Bson meta(String fieldName, String metaFieldName);
    public static Bson fields(Bson... projections);
}

Sorts Utility Class

Factory methods for creating sort specifications.

public final class Sorts {
    public static Bson ascending(String... fieldNames);
    public static Bson descending(String... fieldNames);
    public static Bson orderBy(Bson... sorts);
    public static Bson textScore(String fieldName);
    public static Bson metaTextScore();
}

Usage Examples:

import com.mongodb.client.model.Filters;
import com.mongodb.client.model.Updates;
import com.mongodb.client.model.Projections;
import com.mongodb.client.model.Sorts;

// Complex query with filters
FindIterable<Document> results = collection.find(
    Filters.and(
        Filters.gte("age", 18),
        Filters.lt("age", 65),
        Filters.in("status", "active", "pending"),
        Filters.regex("name", "^A.*", "i")
    )
);

// Update operations
UpdateResult result = collection.updateMany(
    Filters.eq("department", "Engineering"),
    Updates.combine(
        Updates.inc("salary", 5000),
        Updates.set("lastUpdated", new Date()),
        Updates.addToSet("skills", "MongoDB")
    )
);

// Projection and sorting
FindIterable<Document> projected = collection.find()
    .projection(Projections.fields(
        Projections.include("name", "email", "department"),
        Projections.excludeId()
    ))
    .sort(Sorts.orderBy(
        Sorts.ascending("department"),
        Sorts.descending("salary")
    ));
