Class CopyStatement (0.22.0)

public class CopyStatement extends IntermediatePortalStatement

CopyStatement models a COPY table FROM STDIN statement. The same class is used both as an IntermediatePreparedStatement and IntermediatePortalStatement, as COPY does not support any statement parameters, which means that there is no difference between the two.
