Class CxxStubSource

java.lang.Object

gov.llnl.babel.backend.ucxx.CxxStubSource

public class CxxStubSource
extends java.lang.Object

Create and write a header for a Cxx C extension class to wrap a BABEL extendable in a Cxx object. The header has to expose a function to create a wrapped IOR, a function to check if a PyObject is an instance of this extension type, and an import macro.

Constructor Detail

CxxStubSource

public CxxStubSource(Extendable ext,
             Context context)

Create an object capable of generating the header file for a BABEL extendable.

Parameters:

ext - an interface or class symbol that needs a header file for a Cxx C extension class.

CxxStubSource

public CxxStubSource(Extendable ext,
             LanguageWriterForCxx writer,
             Context context)

Create an object capable of generating the header file for a BABEL extendable.

Parameters:

ext - an interface or class symbol that needs a header file for a Cxx C extension class.

Method Detail

generateSupers

public static void generateSupers(Class cls,
                  LanguageWriterForCxx writer,
                  Context context)
                           throws CodeGenerationException

This is a convenience utility function specifically for the generation of super "Stub" functions in the Impl files. The output stream is not closed on exit. A code generation exception is thrown if an error is detected.

Parameters:

cls - The class in which these supers are to be generated

writer - the output writer to which the stub source will be written. This will not be closed.

Throws:

CodeGenerationException - this is a catch all exception. It can be caused by I/O trouble or violations of the data type invariants.

generateCode

public void generateCode()
                  throws CodeGenerationException

Generate the header file for the extendable with which this object was created.

Throws:

CodeGenerationException - this is a catch all exception for problems during the code generation phase.
