Method Details

createURI

URI createURI(String name)

createCompiledClass

File createCompiledClass(String className,
 File destDir,
 SparkTestUtils.JavaSourceFromString sourceFile,
 scala.collection.immutable.Seq<URL> classpathUrls)

Creates a compiled class with the source file. Class file will be placed in destDir.

createCompiledClass

File createCompiledClass(String className,
 File destDir,
 String toStringValue,
 String baseClass,
 scala.collection.immutable.Seq<URL> classpathUrls,
 scala.collection.immutable.Seq<String> implementsClasses,
 String extraCodeBody,
 scala.Option<String> packageName)

Creates a compiled class with the given name. Class file will be placed in destDir.

createJarWithJavaSources

URL createJarWithJavaSources(scala.collection.immutable.Map<String,String> sources,
 File jarFile,
 scala.collection.immutable.Seq<URL> classpathUrls)

Compile Java source code and package the resulting class files into a JAR. Supports classes with package declarations - the JAR will contain the proper directory structure (e.g., org/apache/spark/Foo.class).

Parameters:

sources - map of fully-qualified class name to Java source code

jarFile - the JAR file to create

classpathUrls - additional classpath URLs needed for compilation

Returns:

URL of the created JAR file

createJarWithScalaSources

URL createJarWithScalaSources(scala.collection.immutable.Seq<File> sourceFiles,
 File jarFile,
 scala.collection.immutable.Seq<URL> classpathUrls,
 scala.collection.immutable.Seq<String> excludeClassPrefixes)

Compile Scala source files and package the resulting class files into a JAR.

Parameters:

sourceFiles - Scala source files to compile

jarFile - the JAR file to create

classpathUrls - additional classpath URLs needed for compilation

excludeClassPrefixes - class name prefixes to exclude from the JAR (e.g., Seq("A") excludes A.class, A$.class)

Returns:

(undocumented)

expandManifestClasspath

scala.collection.immutable.Seq<URL> expandManifestClasspath(URL url)

If url points to a "pathing JAR" (a JAR whose manifest declares a Class-Path attribute), return the URLs referenced by that attribute (resolved relative to the JAR's parent directory) followed by the original URL. Otherwise return the original URL unchanged.

Parameters:

url - (undocumented)

Returns:

(undocumented)

listFilesRecursively

scala.collection.immutable.Seq<File> listFilesRecursively(File dir)
