public abstract class GuardingDynamicLinkerExporter
extends Object
implements Supplier<List<GuardingDynamicLinker>>
A class acting as a supplier of guarding dynamic linkers that can be
 automatically loaded by other language runtimes. Language runtimes wishing
 to export their own linkers should subclass this class and implement the
 
Supplier.get() method to return a list of exported linkers and declare the
 subclass in
 /META-INF/services/jdk.dynalink.linker.GuardingDynamicLinkerExporter
 resource of their distribution (typically, JAR file) so that dynamic linker
 factories can discover them using the ServiceLoader mechanism. Note
 that instantiating this class is tied to a security check for the
 RuntimePermission("dynalink.exportLinkersAutomatically") when a
 security manager is present, to ensure that only trusted runtimes can
 automatically export their linkers into other runtimes.- See Also:

Field Details- 
AUTOLOAD_PERMISSION_NAMEThe name of the runtime permission for creating instances of this class. Granting this permission to a language runtime allows it to export its linkers for automatic loading into other language runtimes.- See Also:

Constructor Details- 
GuardingDynamicLinkerExporterprotected GuardingDynamicLinkerExporter()Creates a new linker exporter. If there is a security manager installed checks for theRuntimePermission("dynalink.exportLinkersAutomatically")runtime permission. This ensures only language runtimes granted this permission will be allowed to export their linkers for automatic loading.- Throws:
- SecurityException- if the necessary runtime permission is not granted.
