Class JGrep

java.lang.Object
  extended by org.codehaus.janino.tools.JGrep

public class JGrep
extends Object

Reads a set of compilation units from the file system and searches it for specific JavaTM constructs, e.g. invocations of a particular method. Usage:

 java org.codehaus.janino.JGrep \
           [ -dirs directory-name-patterns ] \
           [ -files file-name-patterns ] \
           { directory-path } \
           -method-invocation class.method(arg-types)
 java org.codehaus.janino.JGrep -help
 
If "-dirs" is not given, then all directory-pathes are scanned for files. The directory-name-patterns work as described in StringPattern.parseCombinedPattern(String).

If "-files" is not given, then all files ending in ".java" are read. The file-name-patterns work as described in StringPattern.parseCombinedPattern(String).

           throws Scanner.ScanException,
                  Parser.ParseException,

getClassFile

public static File getClassFile(String className,
                                File sourceFile,
                                File optionalDestinationDirectory)
Construct the name of a file that could store the byte code of the class with the given name.

If optionalDestinationDirectory is non-null, the returned path is the optionalDestinationDirectory plus the package of the class (with dots replaced with file separators) plus the class name plus ".class". Example: "destdir/pkg1/pkg2/Outer$Inner.class"

If optionalDestinationDirectory is null, the returned path is the directory of the sourceFile plus the class name plus ".class". Example: "srcdir/Outer$Inner.class"

Parameters:
className - E.g. "pkg1.pkg2.Outer$Inner"
sourceFile - E.g. "srcdir/Outer.java"
optionalDestinationDirectory - E.g. "destdir"
