<hr><a name="_details"></a><h2>Detailed Description</h2>
A single input source for an XML entity.
<p>
<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 <a class="el" href="class_Parser.html#a6">Parser::parse</a> method, or as the return value of the <a class="el" href="class_EntityResolver.html#a2">EntityResolver::resolveEntity</a> 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 <a class="el" href="class_InputSource.html#a1">makeStream</a>() method, and provides a type of stream of the correct type for the input source it represents.
<p>
<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>
An input source can be set to force the parser to assume a particular encoding for the data that input source reprsents, via the <a class="el" href="class_InputSource.html#a5">setEncoding</a>() method.
<p>
This method returns name of the encoding that is to be forced. If the encoding has never been forced, it returns a null pointer.
<p>
<dl compact><dt>
<b>Returns: </b><dd>
The forced encoding, or null if none was supplied. </dl><dl compact><dt>
