Class GoloClassLoader

java.lang.Object

java.lang.ClassLoader

org.eclipse.golo.compiler.GoloClassLoader

public final class GoloClassLoader
extends java.lang.ClassLoader

Provides a facility to dynamically load Golo source code and access the generated code from a dedicated class loader.

Golo source files can be compiled and the resulting JVM bytecode be injected into the class loader. It is important to note that this class loader definition is not thread safe.

This class loader does not support reloading. Attempts to load source files that may produce the same bytecode definitions will resulting in exceptions.

Method Detail

getCompiler

public GoloCompiler getCompiler()

load

public java.lang.Class<?> load(java.lang.String goloSourceFilename,
                               java.io.Reader sourceCode)
                        throws GoloCompilationException

Compiles and loads the resulting JVM bytecode for a Golo source file.

Parameters:

goloSourceFilename - the source file name.

sourceCode - the source reader.

Returns:

the class matching the Golo module defined in the source.

Throws:

GoloCompilationException - if either of the compilation phase failed.

load

public java.lang.Class<?> load(java.io.File goloSourceFile)
                        throws GoloCompilationException,
                               java.io.IOException

Throws:

GoloCompilationException

java.io.IOException

load

public java.lang.Class<?> load(GoloModule module)

Compiles and loads the resulting JVM bytecode for a Golo module IR.

Parameters:

module - the Golo module IR to load.

Returns:

the class matching the Golo module defined in the IR.

Throws:

GoloCompilationException - if either of the compilation phase failed.
