Examples of BlobType

org.apache.torque.test.dbobject.BlobType
The skeleton for this class was autogenerated by Torque on: [Wed Feb 27 08:39:09 CET 2013] You should add additional methods to this class to meet the application requirements. This class will only be generated as long as it does not already exist in the output directory.
org.teiid.core.types.BlobType
Represent a value of type "blob", which can be streamable from client
