                                         Iterator<? extends CharSequence> requiredPackages)

Description copied from interface: PackageModuleMapper

moduleRequiredFor.

Specified by:

moduleRequiredFor in interface PackageModuleMapper

Parameters:

moduleName - a CharSequence object.

moduleInfoFrom

protected ModuleInfo moduleInfoFrom(Path path)
                             throws IOException

Extracts ModuleInfo for the given JAR.

• If the #HEADER_AUTOMATIC_MODULE_NAME header is encountered, then a SYNTHETIC module is generated exporting all packages
• Header values Add-Exports and Add-Opens are ignored (though methods exposed to subclasses)

Parameters:

path - a Path to a JAR (zip file or exploded directory).

Returns:

a ModuleInfo instance, possibly SYNTHETIC, or null if no module-info can be derived.

Throws:

IOException - if thrown by the underlying.
