- * $Log: InputSource.hpp,v $
- * Revision 1.10 2001/11/21 16:14:32 tng
- * Schema: New method InputSource::get/setIssueFatalErrorIfNotFound to tell the parser whether to issue fatal error or not if cannot find it (the InputSource). This is required for schema processing as it shouldn't be a fatal error if the schema is not found.

- * A single input source for an XML entity.
- *
- * <p>This class encapsulates information about an input source in a
- * single object, which may include a public identifier or a system
- * identifier</p>
- *
- * <p>There are two places that the application will deliver this input
- * source to the parser: as the argument to the Parser::parse method, or as
- * the return value of the EntityResolver::resolveEntity method.</p>
- *
- * <p>InputSource is never used directly, but is the base class for a number
- * of derived classes for particular types of input sources. Derivatives are
- * provided (in the internal/ directory) for URL input sources, memory buffer
- * input sources, and so on.</p>
- *
- * <p>When it is time to parse the input described by an input source, it
- * will be asked to create a binary stream for that source. That stream will
- * be used to input the data of the source. The derived class provides the
- * implementation of the makeStream() method, and provides a type of stream
- * of the correct type for the input source it represents.
- *
- * <p>An InputSource object belongs to the application: the parser never
- * modifies them in any way. They are always passed by const reference so
- * the parser will make a copy of any input sources that it must keep
- * around beyond the call.</p>
