org.eclipse.jdt.core.formatter.CodeFormatter 用来格式化代码的类

摘录自开源软件源码

private static CodeFormatter getCodeFormatter() {
Map options = DefaultCodeFormatterConstants.getEclipseDefaultSettings();
options.put(JavaCore.COMPILER_COMPLIANCE, JavaCore.VERSION_1_5);
options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM, JavaCore.VERSION_1_5);
options.put(JavaCore.COMPILER_SOURCE, JavaCore.VERSION_1_5);
options.put(DefaultCodeFormatterConstants.FORMATTER_ALIGNMENT_FOR_ENUM_CONSTANTS, DefaultCodeFormatterConstants.createAlignmentValue(true, DefaultCodeFormatterConstants.WRAP_ONE_PER_LINE,
DefaultCodeFormatterConstants.INDENT_ON_COLUMN));
options.put(DefaultCodeFormatterConstants.FORMATTER_LINE_SPLIT, "160"); //$NON-NLS-1$
CodeFormatter codeFormatter codeFormatter = ToolFactory.createCodeFormatter(options);
return codeFormatter;
}

public static String formatCode(String source) {
TextEdit edit = getCodeFormatter().format(CodeFormatter.K_UNKNOWN, source, 0, source.length(), 0, System.getProperty("line.separator")); //$NON-NLS-1$
if (edit != null) {
  IDocument document = new Document(source);
  try {
   edit.apply(document);
   return document.get();
  } catch (Exception e) {
   VisualSwingPlugin.getLogger().error(e);
  }
}
