public Parser(Scale top,
              java.lang.String extension)

Method Detail

parse

public abstract CallGraph parse(java.lang.String name,
                                Suite suite,
                                Vector<java.lang.String> macroText)

Parse the specified file. If macroText is not null, the set of defined macros is added to it.

Parameters:

name - the name of the Clef AST (i.e., the file name)

suite - is the collection of call graphs

macroText - is null or is used to collect macro definitions as text strings

Returns:

new CallGraph

getParser

public static Parser getParser(java.lang.String filename,
                               Scale top)

Return the parser to use for the specified file. The file extension is used to look up the appropriate parser.

runPreprocessor

public static void runPreprocessor(java.io.PrintStream out,
                                   java.lang.String filename,
                                   Scale top)
                            throws java.io.IOException

Return the reader to use for the specified file. The file extension is used to look up the appropriate reader.

Throws:

java.io.IOException

getSourceLanguage

public abstract SourceLanguage getSourceLanguage()

Return the correct source langauge instance for this parser.
