| /** |
| * 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> |
