Uses of Extractor in org.apache.crunch.contrib.text

Classes in org.apache.crunch.contrib.text that implement Extractor

class	AbstractCompositeExtractor<T> Base class for Extractor instances that delegates the parsing of fields to other Extractor instances, primarily used for constructing composite records that implement the Tuple interface.
class	AbstractSimpleExtractor<T> Base class for the common case Extractor instances that construct a single object from a block of text stored in a String, with support for error handling and reporting.
