fixtureApiVersionsXml function

String fixtureApiVersionsXml(DirectoryClassSource classes)

Builds a complete synthetic api-versions.xml for classes: every public class and member is listed at since="1", except fixtureNonSdkClasses; classes present in the hand-written fixtures/java/basic/api-versions.xml are taken verbatim from it (so availability tests control them exactly).

Implementation

String fixtureApiVersionsXml(DirectoryClassSource classes) {
  final overridesText = File(
    p.join(findRepoRoot(), 'fixtures', 'java', 'basic', 'api-versions.xml'),
  ).readAsStringSync();
  final overrides = ApiVersionsIndex.parse(overridesText);
  final body = StringBuffer();
  final start = overridesText.indexOf('<class ');
  final end = overridesText.lastIndexOf('</api>');
  body.writeln(overridesText.substring(start, end).trimRight());
  for (final name in classes.classNames) {
    if (overrides.classes.containsKey(name) ||
        fixtureNonSdkClasses.contains(name)) {
      continue;
    }
    final cf = ClassFile.parse(classes.read(name)!);
    final internal = name.replaceAll('.', '/');
    body.writeln('\t<class name="$internal" since="1">');
    if (cf.superName != null) {
      body.writeln('\t\t<extends name="${cf.superName}"/>');
    }
    for (final i in cf.interfaces) {
      body.writeln('\t\t<implements name="$i"/>');
    }
    for (final m in cf.methods) {
      if (m.has(AccessFlags.public | AccessFlags.protected) &&
          !m.has(AccessFlags.synthetic)) {
        body.writeln(
          '\t\t<method name="${m.name.replaceAll('<', '&lt;')}${m.descriptor}"/>',
        );
      }
    }
    for (final f in cf.fields) {
      if (f.has(AccessFlags.public | AccessFlags.protected)) {
