public ParagraphView(Element elem) 
{
        super(elem);
}

Constructs a ParagraphView for the given element.

Parameters:

elem - the element that this view is responsible for

 protected SizeRequirements calculateMinorAxisRequirements(int axis,
    SizeRequirements r) 
{
        r = super.calculateMinorAxisRequirements(axis, r);
        if (BlockView.spanSetFromAttributes(axis, r, cssWidth, cssHeight)) {
            // Offset by the margins so that pref/min/max return the
            // right value.
            int margin = (axis == X_AXIS) ? getLeftInset() + getRightInset() :
                                            getTopInset() + getBottomInset();
            r.minimum -= margin;
            r.preferred -= margin;
            r.maximum -= margin;
        }
        return r;
}

Calculate the needs for the paragraph along the minor axis.

If size requirements are explicitly specified for the paragraph, use that requirements. Otherwise, use the requirements of the superclass javax.swing.text.ParagraphView .

If the {@code axis} parameter is neither {@code View.X_AXIS} nor {@code View.Y_AXIS}, IllegalArgumentException is thrown. If the {@code r} parameter is {@code null,} a new {@code SizeRequirements} object is created, otherwise the supplied {@code SizeRequirements} object is returned.

 public AttributeSet getAttributes() 
{
        if (attr == null) {
            StyleSheet sheet = getStyleSheet();
            attr = sheet.getViewAttributes(this);
        }
        return attr;
}

Fetches the attributes to use when rendering. This is implemented to multiplex the attributes specified in the model with a StyleSheet.

 public float getMaximumSpan(int axis) 
{
        if (!isVisible()) {
            return 0;
        }
        return super.getMaximumSpan(axis);
}

Determines the maximum span for this view along an axis. Returns 0 if the view is not visible, otherwise it calls the superclass method ot get the maximum span.

 public float getMinimumSpan(int axis) 
{
        if (!isVisible()) {
            return 0;
        }
        return super.getMinimumSpan(axis);
}

Determines the minimum span for this view along an axis. Returns 0 if the view is not visible, otherwise it calls the superclass method to get the minimum span.

 public float getPreferredSpan(int axis) 
{
        if (!isVisible()) {
            return 0;
        }
        return super.getPreferredSpan(axis);
}

Determines the preferred span for this view. Returns 0 if the view is not visible, otherwise it calls the superclass method to get the preferred span. axis.

 protected StyleSheet getStyleSheet() 
{
        HTMLDocument doc = (HTMLDocument) getDocument();
        return doc.getStyleSheet();
}

 public boolean isVisible() 
{
        int n = getLayoutViewCount() - 1;
        for (int i = 0; i <  n; i++) {
            View v = getLayoutView(i);
            if (v.isVisible()) {
                return true;
            }
        }
        if (n  > 0) {
            View v = getLayoutView(n);
            if ((v.getEndOffset() - v.getStartOffset()) == 1) {
                return false;
            }
        }
        // If it's the last paragraph and not editable, it shouldn't
        // be visible.
        if (getStartOffset() == getDocument().getLength()) {
            boolean editable = false;
            Component c = getContainer();
            if (c instanceof JTextComponent) {
                editable = ((JTextComponent)c).isEditable();
            }
            if (!editable) {
                return false;
            }
        }
        return true;
}

Indicates whether or not this view should be displayed. If none of the children wish to be displayed and the only visible child is the break that ends the paragraph, the paragraph will not be considered visible. Otherwise, it will be considered visible and return true.

 public  void paint(Graphics g,
    Shape a) 
{
        if (a == null) {
            return;
        }
        Rectangle r;
        if (a instanceof Rectangle) {
            r = (Rectangle) a;
        } else {
            r = a.getBounds();
        }
        painter.paint(g, r.x, r.y, r.width, r.height, this);
        super.paint(g, a);
}

Renders using the given rendering surface and area on that surface. This is implemented to delgate to the superclass after stashing the base coordinate for tab calculations.

 public  void setParent(View parent) 
{
        super.setParent(parent);
        if (parent != null) {
            setPropertiesFromAttributes();
        }
}

Establishes the parent view for this view. This is guaranteed to be called before any other methods if the parent view is functioning properly.

This is implemented to forward to the superclass as well as call the setPropertiesFromAttributes method to set the paragraph properties from the css attributes. The call is made at this time to ensure the ability to resolve upward through the parents view attributes.

 protected  void setPropertiesFromAttributes() 
{
        StyleSheet sheet = getStyleSheet();
        attr = sheet.getViewAttributes(this);
        painter = sheet.getBoxPainter(attr);
        if (attr != null) {
            super.setPropertiesFromAttributes();
            setInsets((short) painter.getInset(TOP, this),
                      (short) painter.getInset(LEFT, this),
                      (short) painter.getInset(BOTTOM, this),
                      (short) painter.getInset(RIGHT, this));
            Object o = attr.getAttribute(CSS.Attribute.TEXT_ALIGN);
            if (o != null) {
                // set horizontal alignment
                String ta = o.toString();
                if (ta.equals("left")) {
                    setJustification(StyleConstants.ALIGN_LEFT);
                } else if (ta.equals("center")) {
                    setJustification(StyleConstants.ALIGN_CENTER);
                } else if (ta.equals("right")) {
                    setJustification(StyleConstants.ALIGN_RIGHT);
                } else if (ta.equals("justify")) {
                    setJustification(StyleConstants.ALIGN_JUSTIFIED);
                }
            }
            // Get the width/height
            cssWidth = (CSS.LengthValue)attr.getAttribute(
                                        CSS.Attribute.WIDTH);
            cssHeight = (CSS.LengthValue)attr.getAttribute(
                                         CSS.Attribute.HEIGHT);
        }
}

Sets up the paragraph from css attributes instead of the values found in StyleConstants (i.e. which are used by the superclass). Since
