module Neo4j
module Core
# A mixin which adds indexing behaviour to your own Ruby class
# You are expected to implement the method `wrapped_entity` returning the underlying Neo4j Node or Relationship
module Index
# Adds an index on the given property
# Notice that you normally don't have to do that since you simply can declare
# that the property and index should be updated automatically by using the class method #index.
#
# The index operation will take place immediately unlike when using the Neo4j::Core::Index::ClassMethods#index
# method which instead will guarantee that the neo4j database and the lucene database will be consistent.
# It uses a two phase commit when the transaction is about to be committed.
#
# @see Neo4j::Core::Index::ClassMethods#add_index
#
def add_index(field, value=self[field])
converted_value = Neo4j::TypeConverters.convert(value, field, self.class)
self.class.add_index(wrapped_entity, field.to_s, converted_value)
end
# Removes an index on the given property.
# Just like #add_index this is normally not needed since you instead can declare it with the
# #index class method instead.
#
# @see Neo4j::Core::Index::ClassMethods#rm_index
#
def rm_index(field, value=self[field])
self.class.rm_index(wrapped_entity, field.to_s, value)
