scanner
public Scanner 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

addDelimiterProcessorForChar
private static void addDelimiterProcessorForChar(char delimiterChar, DelimiterProcessor toAdd, java.util.Map<java.lang.Character,DelimiterProcessor> delimiterProcessors)
-
parse
public void parse(SourceLines lines, Node block)
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
void reset(SourceLines lines)
-
text
private Text text(SourceLines sourceLines)
-
parseInline
private java.util.List<? extends Node> parseInline()
Parse the next inline element in subject, advancing our position. On success, return the new inline node. On failure, return null.
-
parseDelimiters
private java.util.List<? extends Node> parseDelimiters(DelimiterProcessor delimiterProcessor, char delimiterChar)
Attempt to parse delimiters like emphasis, strong emphasis or custom delimiters.
-
parseOpenBracket
private Node parseOpenBracket()
Add open bracket to delimiter stack and add a text node to block's children.
-
parseBang
private Node 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
private 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
private void addBracket(Bracket bracket)
-
removeLastBracket
private void removeLastBracket()
-
parseLinkDestination
private java.lang.String parseLinkDestination(Scanner scanner)
Attempt to parse link destination, returning the string or null if no match.
-
parseLinkTitle
private java.lang.String parseLinkTitle(Scanner scanner)
Attempt to parse link title (sans quotes), returning the string or null if no match.
-
parseLinkLabel
java.lang.String parseLinkLabel(Scanner scanner)
Attempt to parse a link label, returning the label between the brackets or null.
-
parseLineBreak
private Node parseLineBreak()
-
parseText
private Node 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)
