CasesCondition
An
XorCondition
represents a list of Condition
(Constituent
) instances of which only one is allowed to be parsed
successfully when the
Constituent.parseArgs(String[], String[], CliContext)
methods are
invoked. The command line arguments syntax { -a ^ -b ^ -c }
specifies that only "-a", only "-b" or only "-c" must be set. In case more
then one is set or none, then the XorCondition
will terminate the
parseArgs(String[], String[], CliContext)
method with an exception.-

parseArgs
public List<? extends Operand<?>> parseArgs(String[] aArgs, String[] aOptions, CliContext aCliCtx) throws ArgsSyntaxException Parses the provided command line arguments and determines the according values by evaluating thisConstituent
instance or, in case of being a node in the syntax tree (such as aCondition
, traversing the childConstituent
instances'Constituent.parseArgs(String[], String[], CliContext)
methods. In case of successfully parsing thisConstituent
and / or the childConstituent
instances, the evaluated command line arguments are returned: Depending on theConstituent
subclasses representing the evaluated command line arguments, instances ofFlag
classes,Option
classes orOperand
classes may be found in the result. In case of parsing failure, an according exception is thrown. ATTENTION: This method does not test for superfluous command line arguments being passed; e.g. command line arguments not being evaluated by any of theConstituent
instance being traversed. This method is commonly used by a rootConstituent
'sArgsParser.evalArgs(String[])
method, which delegates to theConstituent.parseArgs(String[], String[], CliContext)
method and after which it determines whether there are superfluous arguments to be taken care of (by throwing an according exception). Business logic therefore should invoke the root node'sConstituent.parseArgs(String[], String[], CliContext)
method as ignoring superfluous command line arguments will cause unexpected behavior from the point of view of the invoker.- Specified by:
parseArgs
in interfaceConstituent
- Parameters:
aArgs
- The command line arguments to be parsed.aOptions
- The list of options (short and as well as long) which are reserved and cannot be used as value.aCliCtx
- the cli context- Returns:
- The list of evaluated command line arguments being instances of
the
Operand
interfaces or its sub-types. - Throws:
ArgsSyntaxException
- thrown in case of a command line arguments mismatch regarding provided and expected args.

toSynopsis
Returns the human readable (verbose) syntax of implementing class ATTENTION: As of different parenthesis settings for some notations regarding the rootConstituent
and the childConstituent
s, the methodConstituent.toSyntax(CliContext)
is called from inside aConstituent
hierarchy. In case the syntax is to be retrieved from the rootConstituent
or an encapsulating and different type, then the applicable method to be called isSynopsisable.toSynopsis(SyntaxNotation)
, as for some notations it will for example not create the most outer braces.- Specified by:

- Parameters:

- TheCliContext
for which the syntax is being generated.- Returns:
- The human readable (verbose) command line arguments syntax.
