New operation
Public String add (XControl control) throws Exception {
String id = HBaseRowKeyUtil.getRowKey (controlTableName)
Control.setId (id)
Control.setStatus (Status.ADD.getValue ())
PutDeletepd=HBaseConvetorUtil.convetor (control,id)
Super.savePutDelete (controlTableName, pd)
Return id
Update operation
Public String update (XControl control) throws Exception {
String id = control.getId ()
PutDelete pd=HBaseConvetorUtil.convetor (control,id)
Super.savePutDelete (controlTableName, pd)
Return id
}
Query operation
Public XControl getXControl (String id) throws Exception {
Return super.get (XControl.class,controlTableName, id)
}
Delete operation
Public void delete (String id) throws IOException {
Delete (controlTableName, id)
}
