Constructor Detail

LocalRepoLoaderImpl

public LocalRepoLoaderImpl(@NonNull
                           java.io.File root,
                           @NonNull
                           RepoManager manager,
                           @Nullable
                           FallbackLocalRepoLoader fallback,
                           @NonNull
                           FileOp fop)

Constructor. Probably should only be used within repository framework.

Parameters:

root - The root directory under which we'll look for packages.

manager - A RepoManager, notably containing the SchemaModules we'll use for reading and writing LocalPackages

fallback - The FallbackLocalRepoLoader we'll use if we can't find a package in a directory.

fop - The FileOp to use for file operations. Should be FileOpUtils.create() for normal operation.

Method Detail

getPackages

@NonNull
public java.util.Map<java.lang.String,LocalPackage> getPackages(@NonNull
                                                                         ProgressIndicator progress)

Description copied from interface: LocalRepoLoader

Gets our packages, loading them if necessary.

Specified by:

getPackages in interface LocalRepoLoader

Parameters:

progress - A ProgressIndicator used to show progress (unimplemented) and logging.

Returns:

A map of install path to LocalPackage, containing all the packages found in the given root.

needsUpdate

public boolean needsUpdate(long lastLocalRefreshMs,
                           boolean deepCheck)

Checks whether it looks like we need to be reloaded. If deepCheck is false, we just check whether .knownPackages has been updated more recently than lastLocalRefreshMs. If deepCheck is true, we check whether the hash in .knownPackages accurately reflects the currently-installed packages (traversing the SDK directory tree to do so).

Specified by:

needsUpdate in interface LocalRepoLoader

Parameters:

lastLocalRefreshMs - The last time a load was done

deepCheck - How vigorously to check. If false, the check should be quite fast. If true it should still be reasonably fast, but less so.

Returns:

true if a reload is needed, false otherwise.
