public class: AbstractDocument.LeafElement [javadoc | source]

java.lang.Object
   javax.swing.text.AbstractDocument$AbstractElement
      javax.swing.text.AbstractDocument$LeafElement

All Implemented Interfaces:
MutableAttributeSet, TreeNode, Serializable, Element

Direct Known Subclasses:
BidiElement

Implements an element that directly represents content of some kind.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see java.beans.XMLEncoder .

Constructor:

Constructor:
public LeafElement(Element parent, AttributeSet a, int offs0, int offs1) { super(parent, a); try { p0 = createPosition(offs0); p1 = createPosition(offs1); } catch (BadLocationException e) { p0 = null; p1 = null; throw new StateInvariantError("Can't create Position references"); } } 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 >= 0 `offs1` - The end offset >= offs0 since: `1.4` -

 public LeafElement(Element parent,
    AttributeSet a,
    int offs0,
    int offs1) {
            super(parent, a);

                p0 = createPosition(offs0);
                p1 = createPosition(offs1);
            } catch (BadLocationException e) {
                p0 = null;
                p1 = null;
                throw new StateInvariantError("Can't create Position references");
            }
}

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 >= 0

offs1 - The end offset >= offs0

Method from javax.swing.text.AbstractDocument$LeafElement Detail:
public Enumeration children() { return null; } Returns the children of the receiver as an `Enumeration`.
public boolean getAllowsChildren() { return false; } Returns true if the receiver allows children.
public Element getElement(int index) { return null; } Gets a child element.
public int getElementCount() { return 0; } Returns the number of child elements.
public int getElementIndex(int pos) { return -1; } Gets the child element index closest to the given model offset.
public int getEndOffset() { return p1.getOffset(); } Gets the ending offset in the model for the element.
public String getName() { String nm = super.getName(); if (nm == null) { nm = ContentElementName; } return nm; } Gets the element name.
public int getStartOffset() { return p0.getOffset(); } Gets the starting offset in the model for the element.
public boolean isLeaf() { return true; } Checks whether the element is a leaf.
