public ClassFileManager getClassFileManager()

Returns ClassFileManager that is related to this ClassLoader

Returns:

classFileManager of this classLoader

getCompiledClasses

public Set<String> getCompiledClasses()

Retuns unmodifiable set of class names that were compiled

Specified by:

getCompiledClasses in class ScriptClassLoader

Returns:

unmodifiable set of class names that were compiled

getClassesForPackage

public Set<JavaFileObject> getClassesForPackage(String packageName)
                                         throws IOException

Returns list of classes that are members of a package

Parameters:

packageName - package to search for classes

Returns:

list of classes that are package members

Throws:

IOException - if was unable to load class

getRawClassByName

protected byte[] getRawClassByName(String name)
                            throws IOException

Finds class with the specified name from the URL search path. Any URLs referring to JAR files are loaded and opened as needed until the class is found.

Parameters:

name - the name of the class

Returns:

the resulting class data

Throws:

IOException - if failed to load class

IllegalArgumentException - if failed to open input stream for class

getByteCode

public byte[] getByteCode(String className)

Returns bytecode for given className. Array is copy of actual bytecode, so modifications will not harm.

Specified by:

getByteCode in class ScriptClassLoader

Parameters:

className - class name

Returns:

bytecode

getDefinedClass

public Class<?> getDefinedClass(String name)

Returns cached class instance for give name or null if is not cached yet

Specified by:

getDefinedClass in class ScriptClassLoader

Parameters:

name - class name

Returns:

cached class instance or null

setDefinedClass

public void setDefinedClass(String name,
                            Class<?> clazz)

Sets defined class into cache

Specified by:

setDefinedClass in class ScriptClassLoader

Parameters:

name - class name

clazz - class object
