  • Method Details

    • setField

      void setField(String fieldName, Object value)
      Set the existing named field to the given value. The setField method has copy-on-write semantics. So for the modifications to be stored in the cache the WritablePdxInstance must be put into a region after setField has been called one or more times.
      Parameters:
      fieldName - name of the field whose value will be set
      value - value that will be assigned to the field
      Throws:
      PdxFieldDoesNotExistException - if the named field does not exist
      PdxFieldTypeMismatchException - if the type of the value is not compatible with the field
