Class SourceFileIndexer

java.lang.Object
ghidra.sleigh.grammar.SourceFileIndexer
public class SourceFileIndexer extends Object
This class is used to index source files in a SLEIGH language module. The SLEIGH compiler records the index of the source file for a constructor rather than the file name. This is an optimization to avoid repeating the file name in the .sla files.
