Chapter 16. The Infinispan Query DSL

A query is created by invocating the from(Class entityType) method, which returns a QueryBuilder object that is responsible for creating queries for the specified entity class from the given cache.

The QueryBuilder accumulates search criteria and configuration specified through invoking its DSL methods, and is used to build a Query object by invoking the QueryBuilder.build() method, which completes the construction. The QueryBuilder object cannot be used for constructing multiple queries at the same time except for nested queries, however it can be reused afterwards.

Invoke the list() method of the Query object to execute the query and fetch the results. Once executed, the Query object is not reusable. If new results must be fetched, a new instance must be obtained by calling QueryBuilder.build().
