getCommandLineOptions

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

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.

public static Charset getDefaultEncoding(MuleContext muleContext)

Returns:

the configured default encoding, checking in the following order until a value is found:

• muleContext -> MuleConfiguration.getDefaultEncoding()
• The value of the system property 'mule.encoding'
• Charset.defaultCharset()
