## org.apache.cayenne.map
Class QueryBuilder

    java.lang.Object
      org.apache.cayenne.map.QueryBuilder

    public abstract class QueryBuilder

extends java.lang.Object

A builder that constructs Cayenne queries from abstract configuration information defined in cayenne-data-map*.dtd. This abstract builder supports values declared in the DTD, allowing subclasses to define their own Query creation logic.

Since:
  1.1
