Method Details

process

void process(T element,
 CssTokenizer tt,
 Consumer<CssToken> out,
 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

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

Processes the next token(s).

Throws:

IOException

ParseException

process

default ImmutableList<CssToken> process(T element,
 ReadOnlyList<CssToken> in)
                                 throws ParseException

Convenience method for processing tokens.

The default implementation calls process(Object, CssTokenizer, Consumer, Deque).

Parameters:

element - an element of the DOM

in - the input tokens

Returns:

the processed tokens
