Method Detail

reset

public static void reset()

Resets the format to the built-in defaults

setReplacements

public static void setReplacements(Map<String,String> replacements)

Configures the string replacements to be performed before trying to parse the units.

Parameters:

replacements - The replacements to be used. It is strongly advised to use a LinkedHashMap as replacements are run from top to bottom, in order, and the order might influence the results

loadPropertiesOrdered

public static LinkedHashMap<String,String> loadPropertiesOrdered(InputStream is)

Loads a properties file preserving its internal order

Parameters:

is - The input stream to be read

Returns:

The contents as a LinkedHashMap preserving the file contents

setAliases

public static void setAliases(Map<String,String> aliases)

Configures the aliases to be used on the unit parser. An alias is a different name for a unit

parse

public static Unit<?> parse(String spec)

Parses a unit applying the configured set of replacements and aliases

format

public static String format(Unit<?> unit)

Formats the unit

Parameters:

unit - The unit to be formatted

Returns:

A string representation of the same unit.
