createJarWithClasses

public static java.net.URL createJarWithClasses(scala.collection.Seq<String> classNames,
                                String toStringValue,
                                scala.collection.Seq<scala.Tuple2<String,String>> classNamesWithBase,
                                scala.collection.Seq<java.net.URL> classpathUrls)

Create a jar that defines classes with the given names.

Note: if this is used during class loader tests, class names should be unique in order to avoid interference between tests.

Parameters:

classNames - (undocumented)

toStringValue - (undocumented)

classNamesWithBase - (undocumented)

classpathUrls - (undocumented)

Returns:

(undocumented)

createJarWithFiles

public static java.net.URL createJarWithFiles(scala.collection.immutable.Map<String,String> files,
                              java.io.File dir)

Create a jar file containing multiple files. The files map contains a mapping of file names in the jar file to their contents.

Parameters:

files - (undocumented)

dir - (undocumented)

Returns:

(undocumented)

createJar

public static java.net.URL createJar(scala.collection.Seq<java.io.File> files,
                     java.io.File jarFile,
                     scala.Option<String> directoryPrefix)

Create a jar file that contains this set of files. All files will be located in the specified directory or at the root of the jar.

Parameters:

files - (undocumented)

jarFile - (undocumented)

directoryPrefix - (undocumented)

Returns:

(undocumented)

createCompiledClass

public static java.io.File createCompiledClass(String className,
                               java.io.File destDir,
                               org.apache.spark.TestUtils.JavaSourceFromString sourceFile,
                               scala.collection.Seq<java.net.URL> classpathUrls)
