Constructor Details

StringParsing

public StringParsing()

Creates an instance of this StringParsing class and provides access to all Parsing.Parsers and Parsing.Parser combinators in that way. Additionally, the skip Parsing.Parser is initialized in order to skip any white space as defined by the regular expression \s.

• Parsing.setSkipParser(jjparse.Parsing.Parser<? extends T>)

Method Details

literal

public Parsing<Character>.Parser<String> literal(String literal)

Creates a primitive Parsing.Parser that attempts to parse the provided String literal.

Parameters:

literal - The String literal which shall be parsed.

Returns:

A Parsing.Parser which parses the provided String literal.

See Also:

• regex(java.lang.String)

regex

public Parsing<Character>.Parser<String> regex(String pattern)

Creates a primitive Parsing.Parser that attempts to match the provided regular expression (which must be a valid Pattern).

Implementation Note: Be careful of applying the returned Parsing.Parser to an infinite Input, as this might not terminate depending on the regular expression.

Parameters:

pattern - The regular expression which shall be used for matching.

Returns:

A Parsing.Parser that attempts to parse the provided regular expression.

• Pattern
• literal(java.lang.String)

character

public Parsing<Character>.Parser<Character> character(char character)

Creates a primitive Parsing.Parser that attempts to parse the provided Character.

Parameters:

character - The Character which shall be parsed.

Returns:

A Parsing.Parser which parses the provided Character.
