MibCompiler implements high-level MIB transformation processing logic. It executes its actions by calling the following specialized objects: * *readers* - to acquire ASN.1 MIB data * *searchers* - to see if transformed MIB already exists and no processing is necessary * *parser* - to parse ASN.1 MIB into AST * *code generator* - to perform actual MIB transformation * *borrowers* - to fetch pre-transformed MIB if transformation is impossible * *writer* - to store transformed MIB data Required components must be passed to MibCompiler on instantiation. Those components are: *parser*, *codegenerator* and *writer*. Optional components could be set or modified at later phases of MibCompiler life. Unlike singular, required components, optional one can be present in sequences to address many possible sources of data. They are *readers*, *searchers* and *borrowers*. indexcCs0||_||_t|_||_g|_g|_g|_dS)zCreates an instance of *MibCompiler* class.

The *compile* method should be invoked when *MibCompiler* object is operational meaning at least *sources* are specified. Once called with a MIB module name, *compile* will: * fetch ASN.1 MIB module with given name by calling *sources* * make sure no such transformed MIB already exists (with *searchers*) * parse ASN.1 MIB text with *parser* * perform actual MIB transformation into target format with *code generator* * may attempt to borrow pre-transformed MIB through *borrowers* * write transformed MIB through *writer* The above sequence will be performed for each MIB name given in *mibnames* and may be performed for all MIBs referred to from MIBs being processed.
