SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Describes a single package
instance of the nested package tree strucure represented by the
containing package unit
.
While the containing package unit is in the PROXY
state this package info acts as
a package descriptor
in the associated package registry
. When that
package unit is loaded all contained package infos/descriptors are resolved and replaced by their actual packages. At
the same time the describing package info objects are attached as adapters to the resolved packages. This way the
descriptive information is available before and after loading the packages.

- If true
and the containing package unit
is not LOADED
the package unit is implicitely loaded. If false
and this package unit is not
LOADED
null
is returned.boolean isCorePackage()
