  • @Documented
    @Retention(RUNTIME)
    @Target(METHOD)
    @Repeatable(OnVSFields.class)
    public @interface OnVSField
    Annotation for tagging methods to receive VirtualSpace Field events, i.e. for Virtual Field Processors.

    Only 1 acceptable method pattern for this annotation.
    Note: methodName can be any name you want to use.

    Example:

       @VirtualSpace(ref="Proj:/vs/subFolder/OneVS")
       public class MyVSListener
         {
         public MyVSListener()
           {
           ...
           }
    
         // Method called to validate the "FieldName" field.
         @OnVSField(name="FieldName", descr="Validates a Field Name", ops={VSFieldEvent.Op.VALIDATE})
         public void onMyValidate(VSFieldEvent event) throws ValueConversionException
           {
           ...
           }
    
         // Method called to convert the "group/FieldName" field value to other formats.
         @OnVSField(name="group/FieldName", descr="Converts a Field Value", ops={Op.CONVERT_TO_NATIVE}, source={String.class}, target={Boolean.class})
         public void onMyConvert(VSFieldEvent event) throws ValueConversionException
           {
           ...
           }
         }

      java.lang.Class<?>[] target
      The list of supported Value conversion classes that are handled as target conversion from a value, used in the CONVERT_* operations.
    • Element Detail

      • name

        java.lang.String name
        The Name or Relative Path of the Property to associate with the method. The name is either a Name without slash ('/') that is a direct child of the VirtualSpace reference, or a Relative Path from the VirtualSpace root.
        Returns:
        The Property Name path from the VirtualSpace base "ref" reference specification, e.g. "myField" or "group/mySubField".
      • descr

        java.lang.String descr
        The description of the field processor routine, used in the Eclipse UI.
        Returns:
        A descriptive string of the field processor.
      • ops

        VSFieldEvent.Op[] ops
        The list of supported event operations in this instance. Only the event for the supported operations are fired to the annotation implementing method.
        Returns:
        The list of supported events, e.g. VALIDATE and/or CONVERT_*.
      • source

        java.lang.Class<?>[] source
        The list of supported Value conversion classes that are handled as source conversion from a value, used in the CONVERT_* operations.
        Returns:
        One or more supported native conversion classes from:
        • String.class,
        • java.math.BigDecimal.class,
