Class RowAtom

java.lang.Object
  org.scilab.forge.jlatexmath.Atom
      org.scilab.forge.jlatexmath.RowAtom

All Implemented Interfaces:

java.lang.Cloneable, Row

public class RowAtom
extends Atom
implements Row

An atom representing a horizontal row of other atoms, to be seperated by glue. It's also responsible for inserting kerns and ligatures.

Atom	getLastAtom()
int	getLeftType() Get the type of the leftermost child atom.
int	getRightType() Get the type of the rightermost child atom.

RowAtom

public RowAtom(java.util.List<TeXFormula> l)
        throws EmptyFormulaException

Only used while parsing MathML. An empty Mrow is not allowed, otherwise it's possible to create fractions with an empty numerator or denominator.

Parameters:

l - list of objects of the type Formula

Throws:

EmptyFormulaException

Method Detail

getLastAtom

public Atom getLastAtom()

add

public final void add(Atom el)

createBox

public Box createBox(TeXEnvironment env)

Description copied from class: Atom

Convert this atom into a Box, using properties set by "parent" atoms, like the TeX style, the last used font, color settings, ...

Specified by:

createBox in class Atom

Parameters:

env - the current environment settings

Returns:

the resulting box.

setPreviousAtom

public void setPreviousAtom(Dummy prev)

Description copied from interface: Row

Sets the given dummy containing the atom that comes just before the first child atom of this "composed atom". This method will allways be called by another composed atom, so this composed atom will be a child of it (nested). This is necessary to determine the glue to insert between the first child atom of this nested composed atom and the atom that the dummy contains.

Specified by:

setPreviousAtom in interface Row

Parameters:

prev - the dummy that comes just before this "composed atom"

getLeftType

public int getLeftType()

Description copied from class: Atom

Get the type of the leftermost child atom. Most atoms have no child atoms, so the "left type" and the "right type" are the same: the atom's type. This also is the default implementation. But Some atoms are composed of child atoms put one after another in a horizontal row. These atoms must override this method.

Overrides:

getLeftType in class Atom

Returns:

the type of the leftermost child atom

getRightType

public int getRightType()

Description copied from class: Atom

Get the type of the rightermost child atom. Most atoms have no child atoms, so the "left type" and the "right type" are the same: the atom's type. This also is the default implementation. But Some atoms are composed of child atoms put one after another in a horizontal row. These atoms must override this method.

Overrides:

getRightType in class Atom

Returns:

the type of the rightermost child atom
