Class StandardExecutionEnvironment

java.lang.Object

org.eclipse.tycho.core.ee.StandardExecutionEnvironment

All Implemented Interfaces:

Comparable<StandardExecutionEnvironment>, ExecutionEnvironment

public class StandardExecutionEnvironment
extends Object
implements 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.)

Methods

Modifier and Type	Method and Description
int	compareTo(StandardExecutionEnvironment otherEnv)

String	getCompilerTargetLevelDefault() Returns a reasonable compiler target level default for this execution environment.
String	getProfileName()
Properties	getProfileProperties()
Set<String>	getSystemPackages() Returns the list of packages (without versions) provided by the execution environment.
boolean	isCompatibleCompilerTargetLevel(String target) Returns false if classes compiled with the given compiler target level can certainly not be executed on this execution environment.

Method Detail

getProfileName

public String getProfileName()

Specified by:

getProfileName in interface ExecutionEnvironment

getCompilerSourceLevelDefault

public String getCompilerSourceLevelDefault()

Description copied from interface: ExecutionEnvironment

Returns a reasonable compiler source level default for this execution environment.

Specified by:

getCompilerSourceLevelDefault in interface ExecutionEnvironment

Returns:

a compiler source level matching the execution environment, or null if unknown.

getCompilerTargetLevelDefault

public String getCompilerTargetLevelDefault()

Description copied from interface: ExecutionEnvironment

Returns a reasonable compiler target level default for this execution environment.

Specified by:

getCompilerTargetLevelDefault in interface ExecutionEnvironment

Returns:

a compiler target level matching the execution environment, or null if unknown.

toString

public String toString()

Overrides:

toString in class Object

getSystemPackages

public Set<String> getSystemPackages()

Description copied from interface: ExecutionEnvironment

Returns the list of packages (without versions) provided by the execution environment.

Specified by:

getSystemPackages in interface ExecutionEnvironment

compareTo

public int compareTo(StandardExecutionEnvironment otherEnv)

Specified by:

compareTo in interface Comparable<StandardExecutionEnvironment>

getProfileProperties

public Properties getProfileProperties()

isCompatibleCompilerTargetLevel

public boolean isCompatibleCompilerTargetLevel(String target)

Description copied from interface: ExecutionEnvironment
