Class TokenFixer

java.lang.Object

uk.ac.ed.ph.snuggletex.internal.TokenFixer

public final class TokenFixer
extends Object

This takes the parse tree after StyleEvaluator has run and performs grouping operations on the FlowTokens to convert them to a more tree-like structure that is easier to handle.

Once this has run, all BraceContainerToken tokens present in PARAGRAPH mode will have been unwrapped or flattened. They are however kept in MATH and LR mode as they can be used for implicit brackets. (Unwinding of redundantly nested containers is done in all cases, though.)

Many other types of tokens, such as the "new paragraph" or "new list item" token will have been removed, with the surrounding content grouped accordingly.
