Rhys Ulerich commented on LOGCXX-419:
-------------------------------------
Problem appears to be that "KeySet" changes meaning from spi::KeySet to
LoggingEvent::KeySet halfway through the class:
156 /**
157 * Returns the set of of the key values in the MDC
for the event.
158 * The returned set is unmodifiable by the caller.
159 *
160 * @return Set an unmodifiable set of the MDC keys.
161 *␣
162 */
163 KeySet getMDCKeySet() const;
164
165 /**
166 Obtain a copy of this thread's MDC prior to
serialization
167 or asynchronous logging.
168 */
169 void getMDCCopy() const;
170
171 typedef spi::KeySet KeySet;
172 /**
173 * Return a previously set property.
174 * @param key key.
175 * @param dest string to which value, if any, is
appended.
176 * @return true if key had a corresponding value.
177 */
178 bool getProperty(const LogString& key, LogString&
dest) const;
179 /**
180 * Returns the set of of the key values in the
properties
181 * for the event. The returned set is unmodifiable
by the caller.
182 *
183 * @return Set an unmodifiable set of the property
keys.
