Java

simple map iterator

Two versions of Java map iterators.
The good old while-hasNext like way:

Iterator<Map.Entry<Key, Value>> it = theMap.entrySet().iterator(); while (it.hasNext()) { Map.Entry<Key, Value> entry = it.next(); Logger.print(entry.getKey().someMethod() + : + entry.getValue().someMethod()); }

or the modern for-each way:

for (Map.Entry<Key, Value> entry: theMap.entrySet()) { }

depending of VM version and implementation, they can have different or equal performance, so be careful.

Ant: copy some files from non-flat dirs to one flat dir

A piece of ant script, which would copy all *.txt and all *.jks files from different directories and subdirectories to one flat directory.
This uses regexp mapper to delete directory part of paths to found files.

 <copy todir="${bin.dir}" verbose="true"> <fileset dir="${workspace}"> <include name="**/src*/**/*.txt"/> <include name="**/src*/**/*.jks"/> </fileset> <mapper type="regexp" from="^([^/]+)/([^/]+)/(.*)$$" to="\3"/> </copy>
