Class ResourceManager

java.lang.Object

public class ResourceManager

extends Object

Description: manages Plb includes of a program to access all interesting resources of a program (other includes, variable declaration, label definitions).
Notice that on an include not everything may be resolved because the resources are always relative to the source-file and contain everything defined in the souce file and its includes (recursively).
