All Implemented Interfaces:

QueryBuilder<Object>, QueryBuilder.Aggregating<Object>, QueryBuilder.Filtering<Object>, QueryBuilder.FilteringCriteria<Object>, QueryBuilder.Grouping<Object>, QueryBuilder.Paging<Object>, QueryBuilder.Selecting<Object>, QueryBuilder.Sorting<Object>, QueryBuilderTools

Enclosing class:

GenericQuery

public static final class GenericQuery.GenericBuilder
extends Query.Builder<Object>
implements QueryBuilderTools

A class for incrementally build a GenericQuery.

The objective of this builder is to help the developer to construct a Query in a more organic way to ease development and avoid invalid configurations.

Each method returns the same Builder instance, but it is bound by interface which the method returns. This way is simulating a flow and the available valid configurations after the current configuration.
