Method Detail
-
getCommandLineArgs
String[] getCommandLineArgs()
Returns all command line arguments specified when the running framework was started.- Returns:
- the array of command line arguments.
-
getFrameworkArgs
String[] getFrameworkArgs()
Returns the arguments consumed by the framework implementation itself. Which arguments are consumed is implementation specific.- Returns:
- the array of command line arguments consumed by the framework.
-
getNonFrameworkArgs
String[] getNonFrameworkArgs()
Returns the arguments not consumed by the framework implementation itself. Which arguments are consumed is implementation specific.- Returns:
- the array of command line arguments not consumed by the framework.
-
getOSArch
String getOSArch()
Returns the string name of the current system architecture. The value is a user-defined string if the architecture is specified on the command line, otherwise it is the value returned byjava.lang.System.getProperty("os.arch")
.- Returns:
- the string name of the current system architecture
-
getNL
String getNL()
Returns the string name of the current locale for use in finding files whose path starts with$nl$
.- Returns:
- the string name of the current locale
-
getOS
String getOS()
Returns the string name of the current operating system for use in finding files whose path starts with$os$
. ReturnConstants.OS_UNKNOWN
if the operating system cannot be determined.The value may indicate one of the operating systems known to the platform (as specified in
org.eclipse.core.runtime.Platform#knownOSValues
) or a user-defined string if the operating system name is specified on the command line.- Returns:
- the string name of the current operating system
-
getWS
String getWS()
Returns the string name of the current window system for use in finding files whose path starts with$ws$
. Returnnull
if the window system cannot be determined.- Returns:
- the string name of the current window system or
null
-
inDebugMode
boolean inDebugMode()
Returnstrue
if the framework is in debug mode andfalse
otherwise.- Returns:
- whether or not the framework is in debug mode
-
inDevelopmentMode
boolean inDevelopmentMode()
Returnstrue
if the framework is in development mode andfalse
otherwise.- Returns:
- whether or not the framework is in development mode
-
getProperty
String getProperty(String key)
Returns the value for the specified property. Environment Properties are backed by the Java system properties. When the optionosgi.framework.useSystemProperties
is used then the environment properties are specific for each instance of the framework.This method should be used instead of the
System.getProperty(String)
method to avoid the global nature of system properties.- Parameters:
key
- the property key- Returns:
- the value of the property, or null
- Since:
- 3.4
-
setProperty
String setProperty(String key, String value)
Sets the value for the specified property. Environment Properties are backed by the Java system properties. When the optionosgi.framework.useSystemProperties
is used then the environment properties are specific for each instance of the framework.This method should be used instead of the
System.setProperty(String, String)
method to avoid the global nature of system properties.- Parameters:
key
- the property keyvalue
- the value of the property- Returns:
- the old value of the property, or null
- Since:
- 3.4
