userContext - an Object value.
Throws:
SeException - if an error occurs

setRasterProducer

public void setRasterProducer(SeRasterProducer rp)
                       throws SeException
Sets java.awt imaging like producer/comsumer callback interface method on input mode. Feed SeStream insert/update continuously with pieces of image data from external source through the SeInsert/SeUpdate operation.

The SeRasterRenderedImage object is implemented as SeRasterConsumer for ScanLine mode load.

Note: Choose between one of the two available methods for input mode. (i.e, setRasterCallBack() or setRasterProducer()). If both methods are called, then the latest one will take affect. 

  String[]  columnNames = {"attr1", "attr2", "rascol"};
  SeInsert  insert      = new SeInsert (seConnection);
  insert.intoTable (toTableName, columnNames);

  boolean      inputMode = true;
  SeRasterAttr toRasAttr = new SeRasterAttr (inputMode);
  .
  .
  .
  // Set callback func
  MyRasterProducer myProducer = new MyRasterProducer (...);
  toRasAttr.setRasterProducer (myProducer);

  SeRow  toRow = insert.getRowToSet ();
  toRow.setRaster (toRasColPos, toRasAttr);

  insert.execute ();
  insert.close ();
  .
