resolveCodeWithoutArguments
Description copied from class:AbstractMessageSource
Subclasses can override this method to resolve a message without arguments in an optimized fashion, i.e. to resolve without involving a MessageFormat.The default implementation does use MessageFormat, through delegating to the
AbstractMessageSource.resolveCode(String, Locale)
method. Subclasses are encouraged to replace this with optimized resolution.Unfortunately,
java.text.MessageFormat
is not implemented in an efficient fashion. In particular, it does not detect that a message pattern doesn't contain argument placeholders in the first place. Therefore, it is advisable to circumvent MessageFormat for messages without arguments.- Overrides:
resolveCodeWithoutArguments
in classAbstractMessageSource
- Parameters:
code
- the code of the message to resolvelocale
- the locale to resolve the code for (subclasses are encouraged to support internationalization)- Returns:
- the message String, or
null
if not found - See Also:
-
resolveCode
Description copied from class:AbstractMessageSource
Subclasses must implement this method to resolve a message.Returns a MessageFormat instance rather than a message String, to allow for appropriate caching of MessageFormats in subclasses.
Subclasses are encouraged to provide optimized resolution for messages without arguments, not involving MessageFormat. See the
AbstractMessageSource.resolveCodeWithoutArguments(String, Locale)
javadoc for details.- Specified by:
resolveCode
in classAbstractMessageSource
- Parameters:
code
- the code of the message to resolvelocale
- the locale to resolve the code for (subclasses are encouraged to support internationalization)- Returns:
- the MessageFormat for the message, or
null
if not found - See Also:
