Interface HierarchicalReader

All Superinterfaces:

FactoryManaged, Reader, SourceLocationBound

All Known Implementing Classes:

GenericHierarchicalReader

public interface HierarchicalReader
extends Reader

A hierarchical reader can include sources into the string of characters read returned by another reader. Implementation usually do not directly read any source, but rather use a non hierarchical reader to read the source.

To give the hierarchical reader to a Lexical Analyzer is done usually following the pattern:

 Reader reader = someSourceProvider.get("some source name");
 
 HierarchicalReader hierarchicalReader = new SomeHierarchicalReader();
 hierarchicalReader.include(reader);
 
 LexicalAnalyzer lexicalAnalyzer = new ScriptBasicLexicalAnalyzer();
 la.set(hierarchicalReader);
