AlternateParser

class AlternateParser(parsers: Collection<IMfmParser>) : IMfmParser

An implementation of IMfmParser that searches for a given string in a given string. The input string is expected to satisfy any IMfmParser passed to parsers. If all parsers fail, this implementation treats the search as failing as well.

Parameters

parsers

A collection of IMfmParser to be used for searching.

Constructors

AlternateParser

constructor(parsers: Collection<IMfmParser>)

constructor(vararg parsers: IMfmParser)

Functions

find

open override fun find(input: String, startAt: Int, context: IMfmParserContext): IMfmParserResult

Finds a substring in the input string starting from a given index.

not

open fun not(): IMfmParser

Returns a negative (not) version of the current MFM parser. A negative parser will return a failure result if the substring is found.

optional

open fun optional(): IMfmParser

Returns an optional version of the current substring parser. An optional parser will return a successful result even if the substring is not found.
