Re: [eclipse-dev] Assert and ListenerList
|
In Doug's message to the UI list, he mentions that the new ListenerList
has an (int) constructor that has different semantics than the one in
JFace, which will make it error-prone to adapt to.
Is it possible to remove this ambiguity, e.g. by using static factory
methods such as ListenerList.newIdentityList() and .newEqualityList()?
It would be nice if the initial capacity could be specified via the
constructor and/or factory methods too.
Having an (int capacity, int mode) constructor would also help remove the
ambiguity.

[eclipse-dev] Assert and ListenerList
The new org.eclipse.equinox.common plugin (exported by
org.eclipse.core.runtime) has three very familiar classes as new API:
Assert, AssertionFailedException and ListenerList. There are *many*
copies of these classes in the SDK, so now is a good time to start using
these canonical implementations and deleting your non-API copies.
ListenerList in particular has had some thread safety bugs fixed since
most people copied it, so using the runtime copy will ensure you are
getting all the latest fixes. Here are the copies of these classes that I
found in a search on today's I-build:
org.eclipse.core.internal.commands.util.Assert
org.eclipse.core.internal.expressions.Assert
org.eclipse.jdt.internal.core.Assert
org.eclipse.jdt.internal.corext.Assert
org.eclipse.jface.text.Assert
org.eclipse.jface.util.Assert
org.eclipse.ltk.internal.core.refactoring.Assert
