类 SimpleCommandLineArgsParser

java.lang.Object
cn.taketoday.core.env.SimpleCommandLineArgsParser
public final class SimpleCommandLineArgsParser extends Object
Parses a String[] of command line arguments in order to populate a CommandLineArgs object.

Working with option arguments

Option arguments must adhere to the exact syntax: 

--optName[=optValue]

That is, options must be prefixed with "--" and may or may not specify a value. If a value is specified, the name and value must be separated without spaces by an equals sign ("="). The value may optionally be an empty string.

Valid examples of option arguments

 --foo
 --foo=
 --foo=""
 --foo=bar
 --foo="bar then baz"
 --foo=bar,baz,biz

Invalid examples of option arguments

 -foo
 --foo bar
 --foo = bar
 --foo=bar --foo=baz --foo=biz

End of option arguments

This parser supports the POSIX "end of options" delimiter, meaning that any "--" (empty option name) in the command line signals that all remaining arguments are non-option arguments. For example, "--opt1=ignored", "--opt2", and "filename" in the following command line are considered non-option arguments. 

 --foo=bar -- --opt1=ignored -opt2 filename

Working with non-option arguments

Any arguments following the "end of options" delimiter (--) or specified without the "--" option prefix will be considered as "non-option arguments" and made available through the CommandLineArgs.getNonOptionArgs() method.
