public class OrCondition extends AbstractCondition
An OrCondition represents a list of Condition (Term) instances of which at least one must be parsed successfully when the Term s' Term.parseArgs(String[], String[], CliContext) methods are invoked. The command line arguments syntax { -a | -b | -c } specifies that at least "-a", "-b" or "-c" must be set. In case none is set , then the OrCondition will terminate the parseArgs(String[], String[], CliContext) method with an exception.

    • parseArgs

      public Operand<?>[] parseArgs(String[] aArgs, String[] aKeywords, CliContext aCliCtx) throws ArgsSyntaxException
      Parses the given command line arguments using the provided keyword set and CLI context.

      This method represents the core parsing operation. It evaluates this Term or, if this term is an inner node, delegates parsing to its child terms.

      The aKeywords parameter defines reserved tokens such as option names that must not be interpreted as operand values.

      This method does not validate whether all arguments have been consumed. Superfluous arguments must be handled by the caller.

      Parameters:
      aArgs - The command line arguments to parse
      aKeywords - Reserved option and keyword tokens
      aCliCtx - The CliContext controlling parsing and rendering
      Returns:
      The evaluated operands
      Throws:
      ArgsSyntaxException - If the arguments do not match the syntax

    • toSynopsis

      public String toSynopsis(CliContext aCliCtx)
      Creates the synopsis for the syntax hierarchy.

      The difference between a synopsis and a syntax is the most outer parenthesis settings for some notations: The Term.toSyntax(CliContext) method is called from inside a syntax tree whereas the Synopsisable.toSynopsis(CliContext) method is called from the hierarchy's root, as for some notations require the creation of the most outer braces.

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

    • withVisible

      public OrCondition withVisible(boolean isVisible)

      Visibility in this context means displaying or hiding this Term's existence to the user (defaults to true).

    • 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:
      getException in interface org.refcodes.exception.ExceptionAccessor<ArgsSyntaxException>
      Specified by:
      getException in interface Term
      Returns:
      The ArgsSyntaxException exception occurring while parsing the arguments.

    • setVisible

      public void setVisible(boolean isVisible)

      Visibility in this context means displaying or hiding this Term's existence to the user (defaults to true).

      Specified by:
      setVisible in interface Term
      Specified by:
      setVisible in interface org.refcodes.graphical.VisibleAccessor.VisibleMutator

    • toArgsDiff

      protected static String[] toArgsDiff(String[] aArgs, List<? extends Operand<?>> aArgsSubset)
      Creates the difference between the provided set and the provided Lists therein found argument arrays subset (as of Operand.getParsedArgs()).
      Parameters:
      aArgs - The set to be used for the diff operation.
      aArgsSubset - The subset to be used for the diff operation being the lists containing the Operand instances whose command line arguments are to be diffed.
      Returns:
      The difference between the set and the subset.

    • toArgsDiff

      protected static String[] toArgsDiff(String[] aArgs, Operand<?>[] aArgsSubset)
      Creates the difference between the provided set and the provided Lists therein found argument arrays subset (as of Operand.getParsedArgs()).
      Parameters:
      aArgs - The set to be used for the diff operation.
      aArgsSubset - The subset to be used for the diff operation being the lists containing the Operand instances whose command line arguments are to be diffed.
      Returns:
      The difference between the set and the subset.

    • toArgsDiff

      protected static String[] toArgsDiff(String[] aArgs, String[] aArgsSubset)
      Creates the difference between the provided set and the provided subset.
      Parameters:
      aArgs - The set to be used for the diff operation.
      aArgsSubset - The subset to be used for the diff operation.
      Returns:
      The difference between the set and the subset.

    • toParsedArgs

      protected static String[] toParsedArgs(Operand<?>[]... aOperands)
      Takes all Operand instances found in the provided Lists and adds all therein found argument arrays (as of Operand.getParsedArgs()) to the result.
      Parameters:
      aOperands - The lists containing the Operand instances whose command line arguments are to be added to the result.
      Returns:
      All the command line arguments detected in the provided Operands Lists.
