Class StyleEvaluator

java.lang.Object

uk.ac.ed.ph.snuggletex.internal.StyleEvaluator

public final class StyleEvaluator
extends Object

This calculates the ComputedStyle for each raw parsed Token. It is used directly after LaTeXTokeniser but before the TokenFixer.

Once this has run, all Commands and Environments with a StyleDeclarationInterpretation will have been removed from the parse tree. This corresponds to commands such as \bf, \textrm{...} and environments like \begin{em}...\end{em}. Each Token remaining in the tree will have its Token.setComputedStyle(ComputedStyle) called to indicate the resulting "style" it will have.
