Example 26 with Content

use of org.apache.aries.application.Content in project aries by apache.

the class EquinoxFrameworkUtils method calculateSystemPackagesToFlow.

/**
   * Calculates which system packages should be flowed 
   * to a child framework based on what packages the 
   * child framework imports. Equinox will require anything imported by the 
   * child framework which is available from the system bundle 
   * in the parent framework to come from the system bundle 
   * in the child framework. However, we don't want to flow 
   * all the extra system packages by default since we want CBAs 
   * which use them to explicitly import them.
   * @param importPackage
   * @return
