Method Detail

orderedParseAttempter

@SafeVarargs
public static Function<CharSequence,TemporalAccessor> orderedParseAttempter(Function<CharSequence,TemporalAccessor>... parsers)

Returns an ordered functional blend of all input parsers. The attempter will try all functions until it succeeds. If none succeed will re-throw the first exception

Parameters:

parsers - ordered sequence of parsers to try to convert a CharSequence into a TemporalAccessor

Returns:

ordered functional blend of all input parsers

parse

public static TemporalAccessor parse(CharSequence dateChars)

Convenience method for permissive parsing using the ALL_PARSER

Parameters:

dateChars - date-string

Returns:

parsed TemporalAccessor

parseWithDefaults

public static TemporalAccessor parseWithDefaults(CharSequence dateChars)

Convenience method for permissive parsing using the ALL_PARSER_WITH_DEFAULTS

Parameters:

dateChars - date-string

Returns:

parsed TemporalAccessor
