我使用Eclipse JDT API来格式化我生成的java源文件。 我可以使用哪些选项强制格式化输出,如下所示:
@Annotation1
@Annotation2
@Annotation3
@Annotation4
public class TheClass {
private static final int PAGE_SIZE = 10;
@Annotation5
private Object o1;
@Annotation5
private Object o2;
@Annotation6
@Annotation7
public void doSomething(@Annotation8 @Annotation Object dto) {
// some works
}
}
据我所知,DefaultCodeFormatterOptions
有insert_new_line_after_annotation
字段,在所有注释后添加新行,甚至是方法参数注释。但我想在类型方法或类型注释之后添加换行符
Edit:
这是格式化代码:
public String format(String code)
throws MalformedTreeException, BadLocationException {
Map options = new java.util.HashMap();
options.put(JavaCore.COMPILER_SOURCE, "1.5");
options.put(JavaCore.COMPILER_COMPLIANCE, "1.5");
options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM, "1.5");
DefaultCodeFormatterOptions cfOptions =
DefaultCodeFormatterOptions.getDefaultSettings();
cfOptions.insert_new_line_after_annotation = false;
cfOptions.comment_insert_new_line_for_parameter = true;
cfOptions.blank_lines_before_method = 1;
cfOptions.number_of_empty_lines_to_preserve= 1;
cfOptions.tab_char = DefaultCodeFormatterOptions.SPACE;
CodeFormatter cf = new DefaultCodeFormatter(cfOptions, options);
TextEdit te = cf.format(CodeFormatter.K_UNKNOWN, code, 0,
code.length(), 0, null);
IDocument dc = new Document(code);
te.apply(dc);
return dc.get();
}
答案 0 :(得分:1)
DefaultCodeFormatterOptions为注释的每个可能上下文注释后的新行都有单独的字段
public boolean insert_new_line_after_annotation_on_type;
public boolean insert_new_line_after_annotation_on_field;
public boolean insert_new_line_after_annotation_on_method;
public boolean insert_new_line_after_annotation_on_package;
public boolean insert_new_line_after_annotation_on_parameter;
public boolean insert_new_line_after_annotation_on_local_variable;
所以我猜测insert_new_line_after_annotation_on_type
就是答案......我已经检查过这个行为与IDE本身一样,而不是API。
