[equinox-dev] StateHelperImpl.getExportedPackageMap: map/set initial cap

["Ivanov, Radoslav" <radoslav.ivanov@xxxxxxx>]

Hello

 

I am writing with regards to method “org.eclipse.osgi.internal.resolver.StateHelperImpl.getExportedPackageMap”, which constructs Map and Set with initial capacity. Is there a particular reason for constructing them in that way?

 

For example,

Map<String, Set<ExportPackageDescription>> result = new HashMap<String, Set<ExportPackageDescription>>(11);

or

exports = new HashSet<ExportPackageDescription>(1);

 

IMHO, in most cases, it causes array resizing, which, I saw, reflects to performance analysis.

 

Best regards
