Constructor Summary

OldXpandRegistry(java.lang.Object specificData)

Method Summary

boolean	canHandle(java.lang.String xpandFile) gives the middle end a way to declare if it can and wants to handle a given source file / resource.
java.lang.String	getName()
boolean	mayHandle(java.lang.String resourceName) gives the middle end a way to declare if it could possibly handle the given source file / resource based some weaker checks like filename extensions.
ParsedResource	parseResource(java.lang.String xpandFile) This method asks the middle end to parse a resource for which it declared that it is the appropriate handler, and return the functions contained therein. Implementations are not required to perform any caching because the MiddleEnd implementation takes care of that.
void	setMiddleEnd(MiddleEnd middleEnd) This method is used to break the circular dependency between MiddleEnd and the language specific handlers.
