All Implemented Interfaces:

NlsFormatter<Void>, NlsMessageFormatter

public class NlsMessageFormatterImpl
extends AbstractNlsMessageFormatter

This is the implementation of the NlsMessageFormatter interface.
NOTE:
This is more or less a rewrite of MessageFormat and is syntax-compatible with the MessageFormat-pattern -format. Some special (and somewhat sick) features as modifying internal Formats or FieldPosition are NOT supported. Currently also parsing is NOT supported.
Instead this implementation is immutable and thread-safe. Further it works on any Appendable rather than only on StringBuffer. It also uses the same Appendable for recursive invocations.

Since:

1.0.0

Constructor Detail

NlsMessageFormatterImpl

public NlsMessageFormatterImpl(String pattern,
                               NlsDependencies nlsDependencies)

The constructor.

Parameters:

pattern - is the pattern of the message to format. It is syntax-compatible with MessageFormat.

nlsDependencies - are the NlsDependencies.

Method Detail

format

public final void format(Void nothing,
                         Locale locale,
                         Map<String,Object> arguments,
                         NlsTemplateResolver resolver,
                         Appendable buffer)
                  throws IOException

Description copied from interface: NlsMessageFormatter

This method formats the underlying pattern by filling in the given arguments and writing the result into the given buffer. This method formats the given object according to the given locale.

Parameters:

nothing - has to be null. Only for generic compatibility.

locale - is the locale used for localized formatting.

arguments - is the Map of arguments.

resolver - is the NlsTemplateResolver.

buffer - is where to append the formatted object.

Throws:

IOException - if the given Appendable caused such exception.

getSuffix

public String getSuffix()

Returns:

the suffix to append after all NlsMessageFormatterImpl.PatternSegments.

visit

public void visit(Visitor<String> staticTextVisitor,
                  Visitor<NlsArgument> dynamicArgumentVisitor)

Description copied from interface: NlsMessageFormatter

Visits the child elements of this NlsMessageFormatter.

Parameters:

staticTextVisitor - a Visitor for the static text segments.

dynamicArgumentVisitor - a Visitor for the NlsArguments.
