Interface MessageCatalogFormat

All Known Implementing Classes:
  PropertiesFormat

    public interface MessageCatalogFormat

Interface for writing various message catalog formats.

WARNING: this API is expected to change as we develop additional message catalog formats. In particular, this interface will be extended to support reading message catalogs and further changes may be required.

Implementations of this interface are executed at compile time and therefore must not contain any JSNI code.

Method Summary
`java.lang.String` | `getExtension()` Returns the extension to use for this file type, including the dot.
`void` | `write(TreeLogger logger, java.lang.String locale, com.google.gwt.i18n.rebind.AbstractResource.ResourceList resourceList, java.io.PrintWriter out, JClassType messageInterface)` Write a message catalog file.

Method Detail

### write

    void write(TreeLogger logger,
               java.lang.String locale,
               com.google.gwt.i18n.rebind.AbstractResource.ResourceList resourceList,
               java.io.PrintWriter out,
               JClassType messageInterface)
               throws UnableToCompleteException

  Write a message catalog file.

  Parameters:
    `logger` - TreeLogger for logging errors/etc
    `locale` - locale of this output file
    `resourceList` - the contents to write
    `out` - the PrintWriter to generate output on
    `messageInterface` - the interface to create (so additional annotations may be accessed)
  Throws:
    `UnableToCompleteException` - if a fatal error prevents generating the output file. In this case, the implementation must have already logged an appropriate ERROR message to the logger.

### getExtension

    java.lang.String getExtension()

  Returns the extension to use for this file type, including the dot.
