public class NoneOperand
extends AbstractOperand<Boolean>
implements Operand<Boolean>, org.refcodes.mixin.EnabledAccessor
The
NoneOperand
represents an empty set of arguments, e.g. no command
line argument is being passed. Usually only makes sense near the root of a
Constituent
tree (e.g. inside the main XorCondition
) to test
ALL arguments passed to an application and one invocation may have neither
optional (as of AnyCondition
) nor mandatory arguments allowed.-

parseArgs
public List<Operand<Boolean>> parseArgs(String[] aArgs, String[] aOptions, CliContext aCliContext) 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
- Overrides:
parseArgs
in classAbstractOperand<Boolean>
- 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.aCliContext
- 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.
-
toSyntax
This method is to be called from inside theConstituent
hierarchy; use the methodSynopsisable.toSynopsis(SyntaxNotation)
in case you invoke syntax retrieval from the rootConstituent
. Returns the human readable (verbose) syntax of thisConstituent
instance including, in case of being a node in the syntax tree (such as aCondition
, the syntax of the childConstituent
instances. ATTENTION: As of different parenthesis settings for some notations regarding the rootConstituent
and the childConstituent
s, the methodConstituent.toSyntax(CliContext)
is called from inside theConstituent
hierarchy. In case the syntax is to be retrieved from the rootConstituent
, 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:
toSyntax
in interfaceConstituent
- Overrides:
toSyntax
in classAbstractOperand<Boolean>
- Parameters:
aCliCtx
- TheCliContext
for which the syntax is being generated.- Returns:
- The human readable (verbose) command line arguments syntax.
-
isEnabled
public boolean isEnabled()Determines whether none arguments have been passed.- Specified by:
isEnabled
in interfaceorg.refcodes.mixin.EnabledAccessor
- Returns:
- True in case none arguments have been passed.
-
toType

toType
in classAbstractOperand<Boolean>
- Parameters:
aArg
- the arg- Returns:
- the string
