java_generator.h

This section contains reference documentation for working with protocol buffer classes in C++.

#include <google/protobuf/compiler/java/java_generator.h>
namespace google::protobuf::compiler::java

Generates Java code for a given .proto file.

Classes in this file

CodeGenerator implementation which generates Java code.

class JavaGenerator: public CodeGenerator

#include <google/protobuf/compiler/java/java_generator.h>
namespace google::protobuf::compiler::java

CodeGenerator implementation which generates Java code.

If you create your own protocol compiler binary and you want it to support Java output, you can do so by registering an instance of this CodeGenerator with the CommandLineInterface in your main() function.

virtual bool JavaGenerator::Generate(
        const FileDescriptor * file,
        const std::string & parameter,
        GeneratorContext * generator_context,
        std::string * error) const

Generates code for the given proto file, generating one or more files in the given output directory.

A parameter to be passed to the generator can be specified on the command line. This is intended to be used to pass generator specific parameters. It is empty if no parameter was given. ParseGeneratorParameter (below), can be used to accept multiple parameters within the single parameter command line flag.

Returns true if successful. Otherwise, sets *error to a description of the problem (e.g. "invalid parameter") and returns false.

virtual uint64_t JavaGenerator::GetSupportedFeatures() const

Implement this to indicate what features this code generator supports.

This should be a bitwise OR of features from the Features enum in plugin.proto.
