Method Details

process

void process(T element,
 CssTokenizer tt,
 Consumer<CssToken> out,
 @NonNull Deque<CssFunction<T>> recursionStack)
      throws IOException,
ParseException

Processes all tokens.

Parameters:

element - an element of the DOM

tt - the tokenizer providing input tokens

out - a consumer for the processed tokens

recursionStack -

Throws:

IOException - in case of IO failure

ParseException - in case of a parsing failure

processToken

 @NonNull CssTokenizer tt,
 @NonNull Consumer<CssToken> out,
 @NonNull Deque<CssFunction<T>> recursionStack)
           throws IOException,
ParseException

Processes the next token(s).

Throws:

IOException

ParseException

process

default @NonNull ImmutableList<CssToken> process(T element,
 @NonNull ReadOnlyList<CssToken> in)
