#
# A dynamic query is a proxy object that implements the API of the FieldQuery
# class, but wraps a dynamic field factory and thus applies the query
# components using dynamic field instances.
#--
# Dynamic queries do not hold their own state, but rather proxy to the query
# that generated them, adding components directly to the owning query's
# internal state.
#++
# DynamicQuery instances are publicly generated by the Query#dynamic_query
# factory method.
#
class DynamicQuery < FieldQuery
def initialize(dynamic_field_factory, query) #:nodoc:
@dynamic_field_factory, @query = dynamic_field_factory, query
end
#
# This has the same effect as calling Query#exclude_instance; it is
# included for interface completeness.
#
def exclude_instance(instance)
@query.exclude_instance(instance)
end
#
# This has the same effect as calling Query#exclude_instance; it is
# included for interface completeness.

def dynamic_query(field_name)
@query.dynamic_query(field_name)
end
#
# Add a Sort to the query
#
def add_sort(sort) #:nodoc:
@query.add_sort(sort)
end
#
# Add a component to the query
#
def add_component(component) #:nodoc:
@query.add_component(component)

# DynamicFieldFactory implements the part of the Setup interface that we
# need, so methods in DynamicQuery's superclasses can rely on it without
# knowing what it is.
#
def setup
@dynamic_field_factory
end

# So query facets can be added to the query from within dynamic queries
