Class ExtensionNodeValidator<I>

java.lang.Object
net.sf.basedb.util.overview.validator.ExtensionNodeValidator<I>
All Implemented Interfaces:
NodeValidator<I>
public class ExtensionNodeValidator<I> extends Object implements NodeValidator<I>
Wrapper for node validators that hooks into the extension system when validating nodes. The parent (or core) validator is always invoked first, then the extension system is queried for additional validators. Methods that return a value return the result from the last call (unless nothing else is specified).

      dc - A DbControl to use if the validation needs to access the database
      context - The current overview context
      parentNode - The parent node that is missing the item
      Returns:
      TRUE if a node should be created, FALSE if not

    • preDeniedItem

      public boolean preDeniedItem(DbControl dc, OverviewContext context, Node parentNode)
      Call the same method on the parent validator and then on all extension validator actions. The result from the last call is returned.

      Parameters:
      dc - A DbControl to use if the validation needs to access the database
      context - The current overview context
      parentNode - The parent node that is linked with the item
      Returns:
      TRUE if a node should be created, FALSE if not

    • preValidate

      public boolean preValidate(DbControl dc, OverviewContext context, I item, Node parentNode)
