Bug 80573 Prepare project specific preference options
I200412081200 From Martin's e-mail: I deprecated some methods that access options that will soon be offered per project as well: CodeFormatterUtil.getTabWidth() -> CodeFormatterUtil.getTabWidth(IJavaProject) CodeFormatterUtil.createIndentString(int) -> CodeFormatterUtil.createIndentString(int, IJavaProject) JavaPreferencesSettings.getCodeGenerationSettings() -> JavaPreferencesSettings.getCodeGenerationSettings(IJavaProject) JavaPreferencesSettings.getImportNumberThreshold(IPreferenceStore) -> JavaPreferencesSettings.getImportNumberThreshold(IJavaProject) JavaPreferencesSettings.getImportOrderPreference(IPreferenceStore) -> JavaPreferencesSettings.getImportOrderPreference(IJavaProject) Also make sure to not directly access to the following preference constants: PreferenceConstants.CODEGEN_* PreferenceConstants.ORGIMPORTS_* PreferenceConstants.FORMATTER_COMMENT_* -> Use PreferenceConstants.getPreference(String key, IJavaProject project) to get a JDT.UI preference value using the given project scope DefaultCodeFormatterConstants.* -> Use javaProject.getOption(key, true) to get a preference value using the given scope I fixed most of the references. What is still open: Refactoring:, fix the accesses to the deprecated methods listed above Java Editor, IndentAction, JavaAutoIndentStrategy, ...: Check all accesses to DefaultCodeFormatterConstants, e.g. FORMATTER_TAB_SIZE, FORMATTER_TAB_CHAR to see if the OverlayPreferenceStore is used
