Class SimpleCompiler

Method Details

• main

  public static void main(String[] args) throws Exception

  Throws:

  Exception

• setParentClassLoader

  public void setParentClassLoader(ClassLoader optionalParentClassLoader)

  Description copied from interface: ICookable

  The "parent class loader" is used to load referenced classes. Useful values are:

  System.getSystemClassLoader()	The running JVM's class path
  Thread.currentThread().getContextClassLoader() or null	The class loader effective for the invoking thread
  ICookable.BOOT_CLASS_LOADER	The running JVM's boot class path

  The parent class loader defaults to the current thread's context class loader.

  Specified by:

  setParentClassLoader in interface ICookable

• setDebuggingInformation

  public void setDebuggingInformation(boolean debugSource, boolean debugLines, boolean debugVars)

  Description copied from interface: ICookable

  Determines what kind of debugging information is included in the generates classes. The default is typically '-g:none', and '-g:all' if the system property 'org.codehaus.janino.source_debugging.enable' is set to 'true'.

  Specified by:

  setDebuggingInformation in interface ICookable

• cook

  public final void cook(String optionalFileName, Reader r) throws CompileException, IOException

  Scans, parses and compiles a given compilation unit from the given Reader. After completion, getClassLoader() returns a ClassLoader that allows for access to the compiled classes.

  Specified by:

  cook in interface ICookable

  Specified by:

  cook in class Cookable

  Parameters:

  optionalFileName - Used when reporting errors and warnings.

  Throws:

  CompileException

  IOException

  See Also:

  • ICookable.cook(String, Reader)

• cook

  public void cook(Scanner scanner) throws CompileException, IOException

  Scans, parses and ompiles a given compilation unit from the given scanner. After completion, getClassLoader() returns a ClassLoader that allows for access to the compiled classes.

  Throws:

  CompileException

  IOException

• cook

  public void cook(Java.CompilationUnit compilationUnit) throws CompileException

  Cook this compilation unit directly. See Cookable.cook(java.lang.String, java.io.Reader)

  Throws:

  CompileException

• getClassLoader

  public ClassLoader getClassLoader()

  Description copied from interface: ISimpleCompiler

  Returns a ClassLoader object through which the previously compiled classes can be accessed. This ClassLoader can be used for subsequent ISimpleCompilers in order to compile compilation units that use types (e.g. declare derived types) declared in the previous one.

  This method must only be called after exactly on of the ICookable.cook(String, java.io.Reader) methods was called.

  Specified by:

  getClassLoader in interface ISimpleCompiler

• equals

  public boolean equals(Object o)

  Two SimpleCompilers are regarded equal iff

  • Both are objects of the same class (e.g. both are ScriptEvaluators)
  • Both generated functionally equal classes as seen by ByteArrayClassLoader.equals(Object)

  Overrides:

  equals in class Object

• hashCode

  public int hashCode()

  Overrides:

  hashCode in class Object

• classToType

  protected Java.Type classToType(Location location, Class clazz)

  Wrap a reflection Class in a Java.Type object.

• classesToTypes

  protected Java.Type[] classesToTypes(Location location, Class[] classes)

  Convert an array of Classes into an array ofJava.Types.

• compileToClassLoader

  protected final ClassLoader compileToClassLoader(Java.CompilationUnit compilationUnit) throws CompileException

  Compile the given compilation unit. (A "compilation unit" is typically the contents of a Java™ source file.)

  Parameters:

  compilationUnit - The parsed compilation unit

  Returns:

  The ClassLoader into which the compiled classes were defined

  Throws:

  CompileException

• assertNotCooked

  protected void assertNotCooked()

  Throw an IllegalStateException if this Cookable is already cooked.
