Package org.eclipse.tycho.core.ee

Class StandardExecutionEnvironment

  • All Implemented Interfaces:
    java.lang.Comparable<StandardExecutionEnvironment>, ExecutionEnvironment
    public class StandardExecutionEnvironment
extends java.lang.Object
implements java.lang.Comparable<StandardExecutionEnvironment>, ExecutionEnvironment
    Represents a standard OSGi execution environment profile. See the list of known OSGi profiles in bundle org.eclipse.osgi, file profile.list. Standard execution environment capabilities can be referenced in MANIFEST.MF using the header "Bundle-RequiredExecutionEnvironment". In order to pick the minimal, required profile from the alternatives listed in a BREE header, instances of this class have a total ordering. TODO This class both represents an EE profile (i.e. the concrete EE implementation used by the compiler) and an EE capability (i.e. the capability required via the BREE). This should be separate classes. (An EE profile typically provides multiple EE capabilities.)
