definePackage	back to summary
pack-priv static Package definePackage(String name, String location) Define the `Package` with the given name. The specified location is a jrt URL to a named module in the run-time image, a file URL to a module in an exploded run-time image, or a file path to an entry on the boot class path (java agent Boot-Class-Path or -Xbootclasspath/a. If the given location is a JAR file containing a manifest, the defined Package contains the versioning information from the manifest, if present. Parameters name:String package name location:String location where the package is (jrt URL or file URL for a named module in the run-time or exploded image; a file path for a package from -Xbootclasspath/a)

pack-priv static Package definePackage(String name, String location)

Define the Package with the given name. The specified location is a jrt URL to a named module in the run-time image, a file URL to a module in an exploded run-time image, or a file path to an entry on the boot class path (java agent Boot-Class-Path or -Xbootclasspath/a.

If the given location is a JAR file containing a manifest, the defined Package contains the versioning information from the manifest, if present.
