public interface Constituent
extends org.refcodes.mixin.Resetable, Synopsisable, org.refcodes.mixin.DescriptionAccessor, org.refcodes.mixin.Schemable<CliSchema>
A
Constituent
defines the methods at least required when building a
command line arguments syntax tree for traversing the syntax tree; either for
parsing command line arguments or for constructing the command line arguments
syntax. By providing various implementations of the Constituent
's
subclasses such as Operand
, Option
or Condition
, a
command line arguments syntax tree can be constructed. This syntax tree can
be use to create a human readable (verbose) command line arguments syntax and
to parse an array of command line arguments for determining the
Operand
s', the Flag
es' or the Option
s' values.-

parseArgs
default List<? extends Operand<?>> parseArgs(String[] aArgs, 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'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 theparseArgs(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'sparseArgs(String[], String[], CliContext)
method as ignoring superfluous command line arguments will cause unexpected behavior from the point of view of the invoker.- Parameters:
aArgs
- The command line arguments to be parsed.aCliCtx
- TheCliContext
to use when parsing the arguments.- 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.

method as ignoring superfluous command line arguments will cause unexpected behavior from the point of view of the invoker.- 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.

toValue
Searches for a value being set for the given for given alias in the syntax tree parsing the command line arguments; if a node in the syntax tree has a value for the given alias, then this value is returned.- Type Parameters:
V
- The type of the value being expected.- Parameters:
aAlias
- The alias for which to seek for a value being set.- Returns:
- The according value or null if none has been set for the given alias.
