Constructor Detail

MemoryClassFactoryImpl

public MemoryClassFactoryImpl()

Method Detail

setInput

public void setInput(java.util.Map sourceMap)

Description copied from interface: MemoryClassFactory

Set the input source files to be compiled.

Specified by:

setInput in interface MemoryClassFactory

Parameters:

sourceMap - a map of {className -> source code} pairs. Both the keys and values of the map must be instances of java.lang.String

getOutput

public java.util.Map getOutput()

Description copied from interface: MemoryClassFactory

Get the compiled output files as a map

Specified by:

getOutput in interface MemoryClassFactory

Returns:

a map of {className -> compiled code} pairs. The keys in this map are instances of java.lang.String and the values are instances of byte[]

getSourceReader

public JavaSourceReader getSourceReader(java.lang.String className)
                                 throws java.io.IOException

Description copied from interface: JavaSourceReaderFactory

Get a source reader for a Java class. Called by the compiler for each class it is instructed to compile

Specified by:

getSourceReader in interface JavaSourceReaderFactory

Returns:

a JavaSourceReader for the specified class or null if the source code cannot be found

Throws:

java.io.IOException - if the source code exists but an error obtaining it occured

getClassReader

public JavaClassReader getClassReader(java.lang.String className)
                               throws java.io.IOException

Description copied from interface: JavaClassReaderFactory

Returns a JavaClassReader for the specified class name

Specified by:

getClassReader in interface JavaClassReaderFactory

Parameters:

className - name of class to be read

Returns:

a JavaClassReader for className or null if the class can't be found

Throws:

java.io.IOException - if an error occurs

getClassWriter

public JavaClassWriter getClassWriter(java.lang.String className)
                               throws java.io.IOException

Description copied from interface: JavaClassWriterFactory

Called by the compiler for each class it compiles, to handle the generated output.

Specified by:

getClassWriter in interface JavaClassWriterFactory

Parameters:

className - name of compiled class

Returns:

JavaClassWriter to handle the compiled class

java.io.IOException

setClassLoader

public void setClassLoader(java.lang.ClassLoader cl)

Description copied from interface: MemoryClassFactory

Set the class loader to use to locate existing classes. If not set this defaults to the system class loader. The implementation will use cl.getResource() or equivalent to attempt to locate an existing class

Specified by:

setClassLoader in interface MemoryClassFactory

Parameters:

cl - class loader

loadClass

public java.lang.Class loadClass(java.lang.String className)
                          throws java.lang.ClassNotFoundException

Description copied from interface: MemoryClassFactory

Convenience method to load a class you just compiled in memory

Specified by:

loadClass in interface MemoryClassFactory

Returns:

The loaded class. The implementation will create a new class loader as a child of the class loader assigned in setClassLoader() to load the class.

Throws:

java.lang.ClassNotFoundException
