Constructor Detail

AbstractSubSuper

public AbstractSubSuper(java.lang.String qname,
                        org.apache.batik.dom.AbstractDocument odoc)

Default constructor. Sets MathML Namespace.

Parameters:

qname - Qualified name.

odoc - Owner Document.

Method Detail

getBase

public abstract JEuclidElement getBase()

A MathMLElement representing the base of the script. This is the first child of the element.

Specified by:

getBase in interface MathMLScriptElement

Returns:

value of the base attribute.

getSuperscript

public abstract JEuclidElement getSuperscript()

A MathMLElement representing the superscript of the script. This is the second child of a msup or the third child of a msubsup; retrieval must return null for an msub.

Specified by:

getSuperscript in interface MathMLScriptElement

Returns:

value of the superscript attribute.

getSubscript

public abstract JEuclidElement getSubscript()

A MathMLElement representing the subscript of the script. This is the second child of a msub or msubsup; retrieval must return null for an msup.

Specified by:

getSubscript in interface MathMLScriptElement

Returns:

value of the subscript attribute.

hasChildPostscripts

public boolean hasChildPostscripts(JEuclidElement child,
                                   LayoutContext context)

returns true is the child has postscripts attached to it. In this case, there should be no extra space on the left.

Specified by:

hasChildPostscripts in interface JEuclidElement

Overrides:

hasChildPostscripts in class AbstractJEuclidElement

Parameters:

child - child to test

context - current layout context.

Returns:

true if there are attached postscripts

layoutStageInvariant

protected void layoutStageInvariant(LayoutView view,
                                    LayoutInfo info,
                                    LayoutStage stage,
                                    LayoutContext context)

Layout for elements which are stage independent.

This function will layout an element which is layed out the same no matter what stage it is in. This is the case for most elements.

Notable exceptions are mo and tables.

Overrides:

layoutStageInvariant in class AbstractJEuclidElement

Parameters:

view - View Object for this layout.

info - An info object which will be filled during layout.

stage - current layout stage.

context - current LayoutContext.
