Method Detail

getenv

public static Map getenv()

Get the operating system environment variables. This should work for Windows and Linux.

Returns:

Map or an empty map if there was an error.

getenv

public static String getenv(String name)

isSunJDK

public static boolean isSunJDK()

isAppleJDK

public static boolean isAppleJDK()

isIbmJDK

public static boolean isIbmJDK()

getCommandLineOption

public static String getCommandLineOption(String option,
                          String[] args,
                          String[][] opts)
                                   throws DefaultMuleException

Returns the value corresponding to the given option from the command line, for example if the options are "-config mule-config.xml" getCommandLineOption("config") would return "mule-config.xml"

Throws:

DefaultMuleException

hasCommandLineOption

public static boolean hasCommandLineOption(String option,
                           String[] args,
                           String[][] opts)
                                    throws DefaultMuleException

Checks whether a command line option is set. This is useful for command line options that don't have an argument, like "-cluster", which means that this Mule instance is part of a cluster.

Throws:

DefaultMuleException

getCommandLineOptions

public static Map<String,Object> getCommandLineOptions(String[] args,
                                       String[][] opts)
                                                throws DefaultMuleException

Returns a Map of all options in the command line. The Map is keyed off the option name. The value will be whatever is present on the command line. Options that don't have an argument will have the String "true".

Throws:

DefaultMuleException

parsePropertyDefinitions

public static Map<String,String> parsePropertyDefinitions(String input)

Returns a Map of all valid property definitions in -Dkey=value format. -Dkey is interpreted as -Dkey=true, everything else is ignored. Whitespace in values is properly handled but needs to be quoted properly: -Dkey="some value".

Parameters:

input - String with property definitionn

Returns:

a Map of property String keys with their defined values (Strings). If no valid key-value pairs can be parsed, the map is empty.

legalizeFileName

public static String legalizeFileName(String name)

Ensure a generated file name is legal.

getDefaultEncoding

public static String getDefaultEncoding(MuleContext muleContext)

Returns:

the configured default encoding MuleConfiguration.getDefaultEncoding(), or the value of the system property 'mule.encoding' if MuleContext is null.
