Class CompilerDriver

java.lang.Object
  coins.driver.CompilerDriver

public final class CompilerDriver

extends java.lang.Object

A framework of COINS compiler driver.
A CompilerDriver object represents an execution of whole compilation process which is divided into four passes: preprocess, compile, assemble and link. An object which implements CompilerImplementation must be provided to implement these four passes.
The semantics of driver control options such as -E, -c, -pipe, etc. are determined by this class.

Constructor Summary

CompilerDriver(CompileSpecification spec)
Constructs a framework object.

Method Summary

static java.io.InputStream	getAttachedFileInputStream(java.lang.Class clazz, java.lang.String path) Returns an InputStream of a file, which is in a directory where a loadable class file is in it (or one of sub-directories of the directory).
int	go(CompilerImplementation implementation) Drives compilation processes: preprocess, compile, assemble and link.

getAttachedFileInputStream

public static java.io.InputStream getAttachedFileInputStream(java.lang.Class clazz,
                                                             java.lang.String path)
                                                      throws java.lang.ClassNotFoundException,
                                                             java.io.IOException

Returns an InputStream of a file, which is in a directory where a loadable class file is in it (or one of sub-directories of the directory). Note that the file and the directory may be on a jar/zip file.

Parameters:

clazz - a class object the class

path - a relative path of the directory where the file exists

Returns:

the InputStream object.

Throws:

java.io.IOException - failed to get InputStream

java.lang.ClassNotFoundException - failed to find `clazz' from class-path.

go

public int go(CompilerImplementation implementation)

Drives compilation processes: preprocess, compile, assemble and link.

Parameters:

implementation - a compiler implementation

Returns:

0 if no error, 1 otherwise
