Integer[] numbersA = {0, 2, 4, 5, 6, 8, 9};

Iterable pairs =

    from("b").in(numbersB).
    where(lt("a", "b")).

Features The Quaere DSL is very flexible and it lets you perform a wide range of queries against any data structure that is an array, or implements the java.lang.Iterable or the org.quaere.Queryable interface. Below is an overview of the querying and other features available through the DSL interface, the underlying query expression model and query engine. See the examples section to gain an understanding of how these features are used.

• Ability to perform queries against arrays or data structure implementing the Iterable interface.
• An internal DSL (based on static imports and fluent interfaces) that lets you integrate the query language with regular Java code. No preprocessing or code generation steps are required to use the DSL, simply add a reference to the quaere.jar file (and its dependencies).
• A large number of querying operators including restriction, selection, projection, set, partitioning, grouping, ordering, quantification, aggregation and conversion operators.
• Support for lambda expressions.
• The ability to dynamically define and instantiate anonymous classes.
• Many new “keywords” for Java 1.5 and later.
