Method Detail

createSFBLookupMerger

public static LookupMerger<SourceForBinaryQueryImplementation> createSFBLookupMerger()

Create a simple instance of LookupMerger for SourceForBinaryQueryImplementation. It takes all implemntations it finds inthe provided lookup and iterates them until a result is found.

Returns:

createJFBLookupMerger

public static LookupMerger<JavadocForBinaryQueryImplementation> createJFBLookupMerger()

Create a simple instance of LookupMerger for JavadocForBinaryQueryImplementation. It takes all implemntations it finds inthe provided lookup and iterates them until a result is found.

Returns:

createClassPathProviderMerger

public static LookupMerger<ClassPathProvider> createClassPathProviderMerger(ClassPathProvider defaultProvider)

Creates a LookupMerger for ClassPathProviders, allowing multiple instances of ClassPathProviders to reside in project's lookup. The merger makes sure the classpaths are merged together. When ClassPathProviders appear or disappear in project's lookup, the classpath is updated accordingly.

Parameters:

defaultProvider - the default project ClassPathProvider that will always be asked first for classpath.

Returns:

LookupMerger instance to be put in project's lookup.
