    • clone

      public Object clone() throws CloneNotSupportedException
      Specified by:
      clone in interface Clonable
      Overrides:
      clone in class AbstractOperand<T>
      Throws:
      CloneNotSupportedException

    • getOperation

      public String getOperation()
      Returns the operation assigned to the Directive instance.
      Specified by:
      getOperation in interface Directive<T>
      Specified by:
      getOperation in interface OperationAccessor
      Returns:
      The operation's String.

    • 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.

      Specified by:
      parseArgs in interface Term
      Overrides:
      parseArgs in class AbstractOperand<T>
      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

    • toSchema

      public Schema toSchema()
      Specified by:
      toSchema in interface Schemable<T>
      Overrides:
      toSchema in class AbstractOperand<T>

    • toString

      public String toString()
      Overrides:
      toString in class AbstractOperand<T>

    • 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.
      Overrides:
      setValue in class AbstractOperand<T>
      Parameters:
      aValue - The value to be set for this Operand.

    • contains

      protected static boolean contains(String[] aArgs, String aArg)
      Determines whether a given String is contained in the given String array.
      Parameters:
      aArgs - The String array to be tested whether it contains the given String.
      aArg - The String to be tested whether it is contained in the provided String array.
      Returns:
      True in case the String is contained in the array, else false.

    • getDescription

      public String getDescription()
      Specified by:
      getDescription in interface 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 ExceptionAccessor<ArgsSyntaxException>
      Specified by:
      getException in interface Term
      Returns:
      The ArgsSyntaxException exception occurring while parsing the arguments.

    • isVisible

      public boolean isVisible()

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

      Specified by:
