- ## Constructor Details

  - ### RunElement

    public RunElement(Element parent, AttributeSet a, int offs0, int offs1)
    Constructs an element that represents content within the document (has no children).
    Parameters:
      `parent` - the parent element
      `a` - the element attributes
      `offs0` - the start offset (must be at least 0)
      `offs1` - the end offset (must be at least offs0)
    Since:
      1.4

- ## Method Details

  - ### getName

    public String getName()
    Gets the name of the element.
    Specified by:
      `getName` in interface `Element`
    Overrides:
      `getName` in class `AbstractDocument.LeafElement`
    Returns:
      the name, null if none

  - ### getResolveParent

    public AttributeSet getResolveParent()
    Gets the resolving parent. HTML attributes are not inherited at the model level so we override this to return null.

      `getResolveParent` in interface `AttributeSet`
    Overrides:
      `getResolveParent` in class `AbstractDocument.AbstractElement`
    Returns:
      null, there are none
