RSQL Builder for MongoDB Methods

The RSQLBuilderMongoDB class provides many methods to build the desired RSQL string.

Initialization

• constructor(options) – Initializes a new RSQLBuilderMongoDB instance.

Comparisons Operators (Defining Conditions)

• equal(selector, value) - Appends a condition selector == value.
• notEqual(selector, value) - Appends a condition selector != value.
• lessThan(selector, value) - Appends a condition selector =lt= value.
• lessThanOrEqual(selector, value) - Appends a condition selector =le= value.
• greaterThan(selector, value) - Appends a condition selector =gr= value.
• greaterThanOrEqual(selector, value) - Appends a condition selector =ge= value.
• in(selector, values) - Appends a condition selector =in= (values).
• notIn(selector, value) - Appends a condition selector =out= (values).
• like(selector, regex, options) - Appends a condition selector =regex= value = options.
• notLike(selector, regex, options) - Appends a condition selector =notregex= value = options.
• regex(selector, regex, options) - Appends a condition selector =regex= value = options.
• notRegex(selector, regex, options) - Appends a condition selector =notregex= value = options.

Expression Grouping (Organizing Conditions)

• group(builder) - Wraps the conditions from another RSQLBuilderMongoDB instance in parentheses for grouping.

Logical Operators (Combining Conditions)

• and() – Appends the logical AND operator ;.
• or() - Appends a logical OR operator ,.

RSQL Builder Composition (Combining Multiple RSQL Queries)

• concat(builder) – Appends all expressions from another RSQLBuilderMongoDB instance to the current instance.
• merge(builders) – Merges multiple RSQLBuilderMongoDB instances into grouped conditions.

RSQL String Management (Finalizing the Query)

• toString() - Returns the generated RSQL query string.
• isEmpty() – Returns true if the RSQLBuilderMongoDB instance has no expressions; otherwise, returns false.
• reset() – Clears all expressions, resetting the RSQLBuilder instance.

Static Utilities

• merge(builders) – Creates a new RSQLBuilderMongoDB instance and merges multiple RSQLBuilderMongoDB instances into grouped conditions.
