scanner
Description copied from interface:InlineParserState
Return a scanner for the input for the current position (on the character that the inline parser registered interest for).Note that this always returns the same instance, if you want to backtrack you need to use
Scanner.position()
andScanner.setPosition(Position)
.- Specified by:
scanner
in interfaceInlineParserState

addDelimiterProcessors
private static void addDelimiterProcessors(Iterable<DelimiterProcessor> delimiterProcessors, Map<Character, DelimiterProcessor> map) -
addDelimiterProcessorForChar
private static void addDelimiterProcessorForChar(char delimiterChar, DelimiterProcessor toAdd, Map<Character, DelimiterProcessor> delimiterProcessors) -
parse
Parse content in block into inline children, appending them to the block node.- Specified by:
parse
in interfaceInlineParser
- Parameters:
lines
- the source content to parse as inlineblock
- the node to append resulting nodes to (as children)
-
reset
-
text
-
parseInline
Parse the next inline element in subject, advancing our position. On success, return the new inline node. On failure, return null. -
parseDelimiters
private List<? extends Node> parseDelimiters(DelimiterProcessor delimiterProcessor, char delimiterChar) Attempt to parse delimiters like emphasis, strong emphasis or custom delimiters. -
parseOpenBracket
Add open bracket to delimiter stack and add a text node to block's children. -
parseBang
If next character is [, and ! delimiter to delimiter stack and add a text node to block's children. Otherwise just add a text node. -
parseCloseBracket
Try to match close bracket against an opening in the delimiter stack. Return either a link or image, or a plain [ character. If there is a matching delimiter, remove it from the delimiter stack. -
addBracket
-
removeLastBracket
private void removeLastBracket() -
parseLinkDestination
Attempt to parse link destination, returning the string or null if no match. -
parseLinkTitle
Attempt to parse link title (sans quotes), returning the string or null if no match. -
parseLinkLabel
Attempt to parse a link label, returning the label between the brackets or null. -
parseLineBreak
-
parseText
Parse the next character as plain text, and possibly more if the following characters are non-special. -
scanDelimiters
private InlineParserImpl.DelimiterData scanDelimiters(DelimiterProcessor delimiterProcessor, char delimiterChar) Scan a sequence of characters with code delimiterChar, and return information about the number of delimiters and whether they are positioned such that they can open and/or close emphasis or strong emphasis.- Returns:
- information about delimiter run, or
null
-
processDelimiters
-
removeDelimitersBetween
-
removeDelimiterAndNodes
Remove the delimiter and the corresponding text node. For used delimiters, e.g. `*` in `*foo*`. -
removeDelimiterKeepNode
Remove the delimiter but keep the corresponding node as text. For unused delimiters such as `_` in `foo_bar`. -
