Examples of org.teiid.core.types.Transform.transform()

org.teiid.core.types.Transform.transform()
This method transforms a value of the source type into a value of the target type. @param value Incoming value of source type @return Outgoing value of target type @throws TransformationException if value is an incorrect input type orthe transformation fails
