JdbcWritableBridge (Sqoop 1.4.4 API)

org.apache.sqoop.lib
Class JdbcWritableBridge

java.lang.Object
  extended by org.apache.sqoop.lib.JdbcWritableBridge

public final class JdbcWritableBridge
extends java.lang.Object

Contains a set of methods which can read db columns from a ResultSet into Java types, and do serialization of these types to/from DataInput/DataOutput for use with Hadoop's Writable implementation. This supports null values for all types.
