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.

Specified by:

getResolveParent in interface AttributeSet

Overrides:

getResolveParent in class AbstractDocument.AbstractElement

Returns:

null, there are none
