+ * @class TAO_EC_Masked_Type_Filter
+ *
+ * @brief A masked type filter.
+ *
+ * This filter only accepts events whose type and/or source have
+ * a given value when a bitmask is applied to them.
+ * In short the filter checks that:
+ * (event.header.type & type_mask) == type_value
+ * and that:
+ * (event.header.source & source_mask) == source_value
