      Returns true if getType() is an array, map or collection. Note that from picocli 4.7, char[] arrays are considered single values (similar to String) and are not treated as arrays.
    • isOptional

      boolean isOptional()
      Returns true if getType() is java.util.Optional
      Since:
      4.6
    • isArray

      boolean isArray()
      Returns true if this type is an array multi-value type. Note that from picocli 4.7, char[] arrays are considered single values (similar to String) and are not treated as arrays.
    • isCollection

      boolean isCollection()
    • isMap

      boolean isMap()
    • isEnum

      boolean isEnum()
      Returns true if getType() is an enum.
    • getEnumConstantNames

      List<String> getEnumConstantNames()
    • getClassName

      String getClassName()
    • getClassSimpleName

      String getClassSimpleName()
    • getAuxiliaryTypeInfos

      List<CommandLine.Model.ITypeInfo> getAuxiliaryTypeInfos()
      Returns type information of components or elements of a multivalue type.
    • getActualGenericTypeArguments

      List<String> getActualGenericTypeArguments()
      Returns the names of the type arguments if this is a generic type. For example, returns ["java.lang.String"] if this type is List<String>.
    • getType

      Class<?> getType()
      Returns the class that the option or parameter value should be converted to when matched on the command line. This method is not safe for annotation processors to use.
      Returns:
      the class that the option or parameter value should be converted to
    • getAuxiliaryTypes

      Class<?>[] getAuxiliaryTypes()
      Returns the component class of an array, or the parameter type of a generic Collection, or the parameter types of the key and the value of a generic Map. This method is not safe for annotation processors to use.
      Returns:
      the component type or types of an array, Collection or Map type
