Package com.yahoo.search.query

Class Properties

  • All Implemented Interfaces:
    java.lang.Cloneable
    Direct Known Subclasses:
    DefaultProperties, PropertyAliases, PropertyMap, QueryProfileProperties, QueryProperties, RequestContextProperties, SubProperties
    public abstract class Properties
extends com.yahoo.processing.request.Properties
    Object properties keyed by name which can be looked up using default values and with conversion to various primitive wrapper types.

    Multiple property implementations can be chained to provide unified access to properties backed by multiple sources as a Chain of Responsibility.

    For better performance, prefer CompoundName argument constants over Strings.

    Properties can be cloned. Cloning a properties instance returns a new instance which chains new instances of all chained instances. The content within each instance is cloned to the extent determined appropriate by that implementation.

    This base class simply passes all access on to the next in chain.
