Class CqAttributesFactory

  • java.lang.Object
    • org.apache.geode.cache.query.CqAttributesFactory
  • public class CqAttributesFactory
extends java.lang.Object
    The factory class for the CqAttributes instance. This provides the CqListener setter methods. This class maintains state for and creates new instances of the CqAttributes interface for new CqQuery instances. If you create a factory with the default constructor, then the factory is set up to create attributes with all default settings. You can also create a factory by providing a CqAttributes, which will set up the new factory with the settings provided in that attributes instance.

    Once a CqAttributes is created, it can only be modified after it has been used to create a CqQuery.
