Method Detail

get

public static final java.lang.String get(int code)

Gets a message based on the specified code without formating arguments.

Equivalent to get(code, null).

get

public static final java.lang.String get(int code,
                                         java.lang.Object fmtArg)

Gets a message based on the locale of current user with ONE format-argument.

get

public static final java.lang.String get(int code,
                                         java.lang.Object[] fmtArgs)

Gets a message based on the locale of current user.

Equivalent to get(code, fmtArgs, current_locale). The current_locale argument depends on the implementation.

get

public static java.lang.String get(int code,
                                   java.lang.Object[] fmtArgs,
                                   java.util.Locale locale)

Gets a message based on the specified code. If not found, returns an error message to denote it.

If fmtArgs is not null, MessageFormats.format(java.lang.String, java.lang.Object[], java.util.Locale) is called to format the message. However, unlike MessageFormat's default behavior, all null objects are treated as an empty string rather than "null".

It also recognizes Objects.UNKNOWN.

Parameters:

code - the code

fmtArgs - the argument lists to format the message

locale - the locale of the message to load

Returns:

the message; never be null

getFormatter

public static Messages.Formatter getFormatter()

Returns the formatter used by get(int, Object[], Locale), or null if not set.

setFormatter

public static void setFormatter(Messages.Formatter fmt)

Sets the formatter used by get(int, Object[], Locale).

Default: null.

getType

public static final int getType(int code)

Gets the message type of the specified code.
