Class FieldSetter

    • Constructor Detail

      • FieldSetter

        public FieldSetter​(Object bean,
                           Field f)
    • Method Detail

      • getType

        public Class getType()
        Description copied from interface: Setter
        Gets the type of the underlying method/field.
        Specified by:
        getType in interface Setter
      • isMultiValued

        public boolean isMultiValued()
        Description copied from interface: Setter
        Whether this setter is intrinsically multi-valued.

        When parsing arguments (instead of options), intrinsically multi-valued setters consume all the remaining arguments. So, if the setter can store multiple values, this method should return true.

        This characteristics of a setter doesn't affect option parsing at all; any options can be specified multiple times. In many cases, this is a no-op--but when your shell script expands multiple environment variables (each of which may contain options), tolerating such redundant options can be useful.

        Specified by:
        isMultiValued in interface Setter
      • asFieldSetter

        public FieldSetter asFieldSetter()
        Description copied from interface: Setter
        If this setter encapsulates a field, return the direct access to that field as FieldSetter. This method serves two purposes:
        1. This lets OptionHandlers bypass the collection/array handling of fields. This is useful if you're defining an option handler that produces array or collection from a single argument.
        2. The other is to retrieve the current value of the field (via getValueList()).
        Specified by:
        asFieldSetter in interface Setter
        Returns:
        null if this setter wraps a method.
      • addValue

        public void addValue​(Object value)
        Description copied from interface: Setter
        Adds/sets a value to the property of the option bean.

        A Setter object has an implicit knowledge about the property it's setting, and the instance of the option bean.

        Specified by:
        addValue in interface Setter
      • getValue

        public Object getValue()
      • getValueList

        public List<Object> getValueList()
        Description copied from interface: Getter
        Gets the current value of the property.

        A Getter object has an implicit knowledge about the property it's getting, and the instance of the option bean.

        Specified by:
        getValueList in interface Getter
        Returns:
        empty list or null if there's no current value.
