  - ### Method Detail

    - #### hasSelectors

          public boolean hasSelectors()

      Indicates whether there are any selectors here.
      Specified by:
        `hasSelectors` in interface `SelectorContainer`
      Returns:
        true if there are selectors

    - #### selectorCount

          public int selectorCount()

      Gives the count of the number of selectors in this container
      Specified by:
        `selectorCount` in interface `SelectorContainer`
      Returns:
        the number of selectors

    - #### getSelectors

          public FileSelector[] getSelectors​(Project p)

      Returns the set of selectors as an array.
      Specified by:
        `getSelectors` in interface `SelectorContainer`
      Parameters:
        `p` - the current project
      Returns:
        an array of selectors

    - #### selectorElements

          public java.util.Enumeration<FileSelector> selectorElements()

      Returns an enumerator for accessing the set of selectors.
      Specified by:
        `selectorElements` in interface `SelectorContainer`
      Returns:
        an enumerator for the selectors

    - #### toString

          public java.lang.String toString()

      Convert the Selectors within this container to a string. This will just be a helper class for the subclasses that put their own name around the contents listed here.
      Overrides:
        `toString` in class `DataType`
      Returns:
        comma separated list of Selectors contained in this one

    - #### appendSelector

          public void appendSelector​(FileSelector selector)

      Add a new selector into this container.
      Specified by:
        `appendSelector` in interface `SelectorContainer`
      Parameters:
        `selector` - the new selector to add

    - #### validate

          public void validate()

      This validates each contained selector provided that the selector implements the validate interface.

      Ordinarily, this will validate all the elements of a selector container even if the isSelected() method of some elements is never called. This has two effects:

      - Validation will often occur twice.
      - Since it is not required that selectors derive from BaseSelector, there could be selectors in the container whose error conditions are not detected if their isSelected() call is never made.

          protected void dieOnCircularReference​(java.util.Stack<java.lang.Object> stk,
                                                Project p)

      Description copied from class: `DataType`
      Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

      If one is included, throw a BuildException created by `circularReference`.

      This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

      The general contract of this method is that it shouldn't do anything if `DataType.checked` is true and set it to true on exit.

      Overrides:
        `dieOnCircularReference` in class `DataType`
      Parameters:
        `stk` - the stack of references to check.
        `p` - the project to use to dereference the references.

    - #### clone

          public java.lang.Object clone()

      Clone the selector container.
      Overrides:
        `clone` in class `DataType`
      Returns:
        a deep clone of a selector container.
