Interface LookupMerger<T>

public interface LookupMerger<T>

Allows project lookup to merge instances of known classes and replace them with single instance. To be used in conjunction with the LookupProvider and LookupProviderSupport The interface is to be implemented by the project owner which decides which contracts make sense to have merged and how they are to be merged. The 3rd party LookupProvider implementors provide instances of mergeableClass. LookupProviderSupport.createCompositeLookup(org.openide.util.Lookup, java.lang.String) handles the hiding of individual mergeable instances and exposing the merged instance created by the LookupMerger.

Since:: org.netbeans.modules.projectapi 1.12
