Method Detail

enhanceClassFile

public boolean enhanceClassFile(InputStream inByteCode,
                                OutputStream outByteCode)
                         throws EnhancerUserException,
                                EnhancerFatalError

Description copied from interface: ByteCodeEnhancer

Enhances a given class according to the JDO meta-data. If the input class has been enhanced or not - the output stream is always written, either with the enhanced class or with the non-enhanced class.

Specified by:

enhanceClassFile in interface ByteCodeEnhancer

Parameters:

inByteCode - The byte-code of the class to be enhanced.

outByteCode - The byte-code of the enhanced class.

Returns:

true if the class has been enhanced, false otherwise.

Throws:

EnhancerUserException

EnhancerFatalError

enhanceClassFile

public boolean enhanceClassFile(InputStream inByteCode,
                                OutputStreamWrapper outByteCode)
                         throws EnhancerUserException,
                                EnhancerFatalError

Description copied from interface: ByteCodeEnhancer

Enhances a given class according to the JDO meta-data. If the input class has been enhanced or not - the output stream is always written, either with the enhanced class or with the non-enhanced class.
Furthermore the enhancer has to set the classname of the enhanced class to the output stream wrapper object (it's possible to get the input stream without knowing the classname).

Specified by:

enhanceClassFile in interface ByteCodeEnhancer

Parameters:

inByteCode - The byte-code of the class to be enhanced.

outByteCode - The byte-code of the enhanced class.

Returns:

true if the class has been enhanced, false otherwise.

Throws:

EnhancerUserException

EnhancerFatalError
