Constructor Detail

LocalModuleFinder

private LocalModuleFinder(java.io.File[] repoRoots,
                          PathFilter pathFilter,
                          boolean cloneRoots)

LocalModuleFinder

public LocalModuleFinder(java.io.File[] repoRoots,
                         PathFilter pathFilter)

Construct a new instance.

Parameters:

repoRoots - the repository roots to use

pathFilter - the path filter to use

LocalModuleFinder

public LocalModuleFinder(java.io.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

getRepoRoots

static java.io.File[] getRepoRoots(boolean supportLayersAndAddOns)

getModulePathFiles

private static java.io.File[] getModulePathFiles()

getFiles

private static java.io.File[] getFiles(java.lang.String modulePath,
                                       int stringIdx,
                                       int arrayIdx)

toPathString

private static java.lang.String toPathString(ModuleIdentifier moduleIdentifier)

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

parseModuleXmlFile

public static ModuleSpec parseModuleXmlFile(ModuleIdentifier identifier,
                                            ModuleLoader delegateLoader,
                                            java.io.File... roots)
                                     throws java.io.IOException,
                                            ModuleLoadException

Parse a module.xml file and return the corresponding module specification.

Parameters:

identifier - the identifier to load

delegateLoader - the delegate module loader to use for module specifications

roots - the repository root paths to search

Returns:

the module specification

Throws:

java.io.IOException - if reading the module file failed

ModuleLoadException - if creating the module specification failed (e.g. due to a parse error)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
