Method Detail

getDefaults

public java.util.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 java.util.Map<F,java.lang.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(java.util.Map<java.lang.String,java.lang.Object> raw,
                                                           F[] fields,
                                                           boolean strict,
                                                           java.lang.String 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:

java.lang.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 java.util.Map<java.lang.String,java.lang.Object> parseRaw(java.io.InputStream is)
                                                                 throws java.io.IOException

Parses an input stream into raw key/value pairs.

Parameters:

is - the input stream

Returns:

the raw key/value pairs

Throws:

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

replaceWildcards

public static java.lang.Object replaceWildcards(java.lang.Class<?> type,
                                                java.lang.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.
