Constructor Detail

LocalModuleFinder

public LocalModuleFinder(File[] repoRoots,
                 PathFilter pathFilter)

Construct a new instance.

Parameters:

repoRoots - the repository roots to use

pathFilter - the path filter to use

LocalModuleFinder

public LocalModuleFinder(File[] repoRoots)

Construct a new instance.

Parameters:

repoRoots - the repository roots to use

LocalModuleFinder

public LocalModuleFinder()

Construct a new instance, using the module.path system property or the JAVA_MODULEPATH environment variable to get the list of module repository roots.

This is equivalent to a call to LocalModuleFinder(true).

LocalModuleFinder

public LocalModuleFinder(boolean supportLayersAndAddOns)

Construct a new instance, using the module.path system property or the JAVA_MODULEPATH environment variable to get the list of module repository roots.

Parameters:

supportLayersAndAddOns - true if the identified module repository roots should be checked for an internal structure of child "layer" and "add-on" directories that may also be treated as module roots lower in precedence than the parent root. Any "layers" subdirectories whose names are specified in a layers.conf file found in the module repository root will be added in the precedence of order specified in the layers.conf file; all "add-on" subdirectories will be added at a lower precedence than all "layers" and with no guaranteed precedence order between them. If false no check for "layer" and "add-on" directories will be performed.

Method Detail

findModule

public ModuleSpec findModule(ModuleIdentifier identifier,
                    ModuleLoader delegateLoader)
                      throws ModuleLoadException

Description copied from interface: ModuleFinder

Find a module specification for the given identifier.

Specified by:

findModule in interface ModuleFinder

Parameters:

identifier - the module identifier

delegateLoader - the module loader from which dependencies should be resolved

Returns:

the module specification, or null if no specification is found for this identifier

Throws:

ModuleLoadException

toString

public String toString()

Overrides:

toString in class Object
