Alex Blewitt

contacted on 30 aug 16 _____________ Dr Alex Blewitt has over 20 years of experience in Objective-C and has been using Apple frameworks since NeXTstep 3.0. He upgraded his NeXTstation for a TiBook when Apple released Mac OS X in 2001 and has been developing on it ever since. Alex currently works for an investment bank in London, writes for the on-line technology news site InfoQ and has published two other books for Packt publishing. He also has a number of apps on the Apple AppStore through Bandlem Limited. When he's not working on technology, and if the weather is nice, he likes to go flying from the nearby Cranfield airport. Alex writes regularly at his blog, http://alblue.bandlem.com, as well tweeting regularly from Twitter as @alblue. Acknowledgements This book would not have been possible without the ongoing love and support of my wife Amy, who has helped me through both the highs and lows of life. She gave me the freedom to work during the many late nights and weekends that it takes to produce a book and its associated code repository. She truly is the Lem of my life. I'd also like to thank my parents, Ann and Derek, for their encouragement and support during my formative years. It was this work ethic that allowed me to start my technology career as a teenager and to incorporate my first company before I was 25. I'd also like to congratulate them on their 50th wedding anniversary in 2015, and I look forward to reaching that goal with Amy. Thanks are due especially to the reviewer of this version of the book: Antonio Bello, as well as the previous version of this book: Nate Cook, James Robert and Arvid Gerstmann, who provided excellent feedback on the contents of this book during development and caught many errors in both the text and code. Any remaining errors are my own. I'd also like to thank my children Sam and Holly for inspiring me and hope that they too can achieve anything that they set their minds to. Finally, I'd like to thank Ben Moseley and Eren Kotan, both of whom introduced me to NeXT in the first place and set my career going on a twenty year journey to this book.

Time for action – registering a marker type

The current implementation has a flaw, in that it doesn't appear to fix the problems after they have been resolved. That's because the marker types are kept associated with a resource even if that resource is changed. The reason this isn't seen in Java files is that the builder wipes out all (Java) errors prior to the start of a build, and then adds new ones as applicable. To avoid wiping out other plug-ins' markers, each marker has an associated marker type. JDT uses this to distinguish between its markers and others contributed by different systems. This can be done for MinimarkMarker instances as well.

  1. Open the plugin.xml file in the com.packtpub.e4.minimark.ui project. Add the following extension to define a MinimarkMarker:

    <extension id="com.packtpub.e4.minimark.ui.MinimarkMarker"
 name="Minimark Marker"
 point="org.eclipse.core.resources.markers">
  <persistent value="false"/>
  <super type="org.eclipse.core.resources.problemmarker...
