  • Method Details

    • getFileJavaPackage

      public static String getFileJavaPackage(DescriptorProtos.FileDescriptorProtoOrBuilder file)
      Returns the generated package for the given file descriptor proto.

    • getFileJavaPackage

      public static String getFileJavaPackage(Descriptors.FileDescriptor file)
      Returns the generated package for the given file descriptor.

    • getDefaultJavaPackage

      static String getDefaultJavaPackage(DescriptorProtos.FileOptions fileOptions, String filePackage)
      Returns the default java package for the given file.

    • joinPackage

      static String joinPackage(String a, String b)
      Joins two package segments into a single package name with a dot separator.

    • getProto2ApiDefaultJavaPackage

      static String getProto2ApiDefaultJavaPackage(DescriptorProtos.FileOptions fileOptions, String filePackage)
      Returns the package name to use for a file that is being compiled as proto2-API. If the file is declared as proto1-API, this may involve using the alternate package name.

    • getFileClassName

      public static String getFileClassName(DescriptorProtos.FileDescriptorProtoOrBuilder file)
      Returns the generated unqualified outer file class name for the given file descriptor proto.

    • getFileClassName

      public static String getFileClassName(Descriptors.FileDescriptor file)
      Returns the generated unqualified outer file class name for the given file descriptor.

    • getFileClassNameImpl

      private static String getFileClassNameImpl(DescriptorProtos.FileDescriptorProtoOrBuilder file, JavaFeaturesProto.JavaFeatures resolvedFeatures)

    • getResolvedFileFeatures

      static <T extends Message> T getResolvedFileFeatures(GeneratedMessage.GeneratedExtension<DescriptorProtos.FeatureSet, T> ext, DescriptorProtos.FileDescriptorProtoOrBuilder file)
      Returns the resolved features for the given descriptor proto.

      This method isn't actually naming-specific, but lives here for now because it's the only place it's needed. Once we have a better home for dealing with features in code generators, this should move.

    • getDefaultFileClassName

      static String getDefaultFileClassName(DescriptorProtos.FileDescriptorProtoOrBuilder file, boolean useOldOuterClassnameDefault)
      Returns the default unqualified file class name for the given file.
      Parameters:
      file - the file descriptor proto
      useOldOuterClassnameDefault - whether to use the old default for the outer classname

    • stripProto

      private static String stripProto(String filename)

    • hasConflictingClassName

      private static boolean hasConflictingClassName(DescriptorProtos.FileDescriptorProtoOrBuilder file, String name)
      Checks whether any generated classes conflict with the given name.

    • hasConflictingClassName

      private static boolean hasConflictingClassName(DescriptorProtos.DescriptorProto messageDesc, String name)
      Used by the other overload, descends recursively into messages.

    • underscoresToCamelCase

      static String underscoresToCamelCase(String input, boolean capitalizeNextLetter)
      Converts a name to camel-case.
      Parameters:
      input - the input string to convert
      capitalizeNextLetter - whether to capitalize the first letter

    • underscoresToCamelCase

      static String underscoresToCamelCase(String input)

    • getBytecodeClassName

      public static String getBytecodeClassName(Descriptors.Descriptor message)
      Returns the fully qualified Java bytecode class name for the given message descriptor.

      Nested classes will use '$' as the separator, rather than '.'.

    • getBytecodeClassName

      public static String getBytecodeClassName(Descriptors.EnumDescriptor enm)
      Returns the fully qualified Java bytecode class name for the given enum descriptor.

      Nested classes will use '$' as the separator, rather than '.'.

    • getBytecodeClassName

      static String getBytecodeClassName(Descriptors.ServiceDescriptor service)
      Returns the fully qualified Java bytecode class name for the given service descriptor.

      Nested classes will use '$' as the separator, rather than '.'.

    • getQualifiedFromBytecodeClassName

      static String getQualifiedFromBytecodeClassName(String bytecodeClassName)

    • getQualifiedClassName

      public static String getQualifiedClassName(Descriptors.Descriptor message)
      Returns the fully qualified Java class name for the given message descriptor.

      Nested classes will use '.' as the separator, rather than '$'.

    • getQualifiedClassName

      public static String getQualifiedClassName(Descriptors.EnumDescriptor enm)
      Returns the fully qualified Java class name for the given enum descriptor.

      Nested classes will use '.' as the separator, rather than '$'.

    • getQualifiedClassName

      public static String getQualifiedClassName(Descriptors.ServiceDescriptor service)
      Returns the fully qualified Java class name for the given service descriptor.

      Nested classes will use '.' as the separator, rather than '$'.

    • getClassFullName

      private static String getClassFullName(String nameWithoutPackage, Descriptors.FileDescriptor file, boolean isOwnFile)

    • getNestInFileClass

      private static boolean getNestInFileClass(Descriptors.FileDescriptor file, JavaFeaturesProto.JavaFeatures resolvedFeatures)
      Returns the nest_in_file_class behavior for a given set of features in a specific file.

    • getNestInFileClass

      public static boolean getNestInFileClass(Descriptors.Descriptor descriptor)

    • getNestInFileClass

      public static boolean getNestInFileClass(Descriptors.EnumDescriptor descriptor)
