Method Detail

getDefaults

public Set<F> getDefaults()

Description copied from interface: ParseResult

Gets the set of optional fields whose defaults where used during parsing.

Specified by:

getDefaults in interface ParseResult<F extends ConfigField>

Returns:

the defaults

getValues

public Map<F,Object> getValues()

Description copied from interface: ParseResult

Gets the parsed values.

Specified by:

getValues in interface ParseResult<F extends ConfigField>

Returns:

the values (includes default values)

parse

public ParseResult<F> parse()

Starts parsing.

Returns:

parsing result

parse

public static <F extends ConfigField> ParseResult<F> parse(Map<String,Object> raw,
                                           F[] fields,
                                           boolean strict,
                                           File parent)

Parses raw key/value pairs into a ParseResult object.

Type Parameters:

F - the field enum this parsers uses

Parameters:

raw - the raw key/value input pairs

fields - the fields to use for parsing

strict - the strict if true, parses in strict mode

parent - the parent to resolve relative paths against

Returns:

the parsing result

Throws:

IllegalArgumentException - if any input errors are encountered during parsing. Non-critical errors won't resolve in an exception if not parsing in strict mode.

parseRaw

public static Map<String,Object> parseRaw(InputStream is)
                                   throws IOException

Parses an input stream into raw key/value pairs.

Parameters:

is - the input stream

Returns:

the raw key/value parise

Throws:

IOException - Signals that an I/O exception has occurred.

replaceWildcards

public static Object replaceWildcards(Class<?> type,
                      Object given)

Replaces a given wildcard value with the value the wildcard represents.

Parameters:

type - the type of given value

given - the given value, must not be null

Returns:

the value of given wildcard. If given value is not a wildcard, given value is returned as is.
