Method Details

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in interface org.refcodes.mixin.Clonable

Overrides:

clone in class AbstractOperand<T>

Throws:

CloneNotSupportedException

getLongOption

public String getLongOption()

Returns the long-option representing an Option instance. A long option usually is being prefixed with a double hyphen-minus "--" as defined in ArgsPrefix.POSIX_LONG_OPTION.

Specified by:

getLongOption in interface Option<T>

Returns:

The long-option String.

getShortOption

public Character getShortOption()

Returns the short-option representing an Option instance. A short option usually is being prefixed with a single hyphen-minus "-" as defined in ArgsPrefix.POSIX_SHORT_OPTION.

Specified by:

getShortOption in interface Option<T>

parseArgs

public Operand<?>[] parseArgs(String[] aArgs,
 String[] aOptions,
 CliContext aCliCtx)
                       throws ArgsSyntaxException

Parses the provided command line arguments and determines the according values by evaluating this Term instance or, in case of being a node in the syntax tree (such as a Condition, traversing the child Term instances' Term.parseArgs(String[], String[], CliContext) methods. In case of successfully parsing this Term and / or the child Term instances, the evaluated command line arguments are returned: Depending on the Term subclasses representing the evaluated command line arguments, instances of Flag classes, Option classes or Operand 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 the Term instance being traversed. This method is commonly used by a root Term's ParseArgs.evalArgs(String[]) method, which delegates to the Term.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's Term.parseArgs(String[], String[], CliContext) method as ignoring superfluous command line arguments will aCause unexpected behavior from the point of view of the invoker.

Specified by:

parseArgs in interface Term

Overrides:

parseArgs in class AbstractOperand<T>

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.

toSchema

public CliSchema toSchema()

Specified by:

toSchema in interface org.refcodes.schema.Schemable

Specified by:

toSchema in interface Term

Overrides:

toSchema in class AbstractOperand<T>

toSyntax

public String toSyntax(CliContext aCliCtx)

This method is to be called from inside the Term hierarchy; use the method Synopsisable.toSynopsis(SyntaxNotation) in case you invoke syntax retrieval from the root Term. Returns the human readable (verbose) syntax of this Term instance including, in case of being a node in the syntax tree (such as a Condition, the syntax of the child Term instances. ATTENTION: As of different parenthesis settings for some notations regarding the root Term and the child Terms, the method Term.toSyntax(CliContext) is called from inside the Term hierarchy. In case the syntax is to be retrieved from the root Term, then the applicable method to be called is Synopsisable.toSynopsis(SyntaxNotation), as for some notations it will for example not create the most outer braces.

Specified by:

toSyntax in interface Term

Overrides:

toSyntax in class AbstractOperand<T>

Parameters:

aCliCtx - The CliContext for which the syntax is being generated.

Returns:

The human readable (verbose) command line arguments syntax.

Parameters:

aArgs - The arguments participating tin the exception.

aCliCtx - The context to use when creating the exception's details.

Returns:

The accordingly created ArgsSyntaxException instance.

setParsedArgs

protected void setParsedArgs(String[] aArgs)

Sets the command line argument(s) representing the Operand and its value as parsed by the AbstractOperand.parseArgs(String[], String[], CliContext) method.

Overrides:

setParsedArgs in class AbstractOperand<T>

Parameters:

aArgs - The command line arguments representing this Operand with its value.

setValue

protected void setValue(T aValue)

Sets the value for the Operand as parsed by the AbstractOperand.parseArgs(String[], String[], CliContext) method.

getDescription

public String getDescription()

Specified by:

getDescription in interface org.refcodes.mixin.DescriptionAccessor

getException

public ArgsSyntaxException getException()

Retrieves the ArgsSyntaxException exception in case invoking Term.parseArgs(String[], CliContext) failed. The exception (and the according suppressed ones alongside the causes) does not necessarily have been thrown by the Term.parseArgs(String[], CliContext) method depending on the semantics of the Term handing the exception (the AnyCondition provides any exceptions it caught even though it did not throw them as of its semantics).

Specified by:
