# DataExtractors present an internal API for the indexer to use to extract
# field values from models for indexing. They must implement the #value_for
# method, which takes an object and returns the value extracted from it.
#
module DataExtractor #:nodoc: all
#
# AttributeExtractors extract data by simply calling a method on the block.
#
class AttributeExtractor
def initialize(attribute_name)
@attribute_name = attribute_name
end
def value_for(object)
object.send(@attribute_name)
end
end
#
# BlockExtractors extract data by evaluating a block in the context of the
# object instance, or if the block takes an argument, by passing the object
# as the argument to the block. Either way, the return value of the block is
# the value returned by the extractor.

class BlockExtractor

@block = block
