<div class="textblock"><p>Implementation of input stream based on a file. </p>
|

<p>This class is a specialization of <a class="el" href="classsf_1_1InputStream.html" title="Abstract class for custom file input streams. ">InputStream</a> that reads from a file on disk.</p>
|
||||
<p>It wraps a file in the common <a class="el" href="classsf_1_1InputStream.html" title="Abstract class for custom file input streams. ">InputStream</a> interface and therefore allows to use generic classes or functions that accept such a stream, with a file on disk as the data source.</p>

<p>In addition to the virtual functions inherited from <a class="el" href="classsf_1_1InputStream.html" title="Abstract class for custom file input streams. ">InputStream</a>, <a class="el" href="classsf_1_1FileInputStream.html" title="Implementation of input stream based on a file. ">FileInputStream</a> adds a function to specify the file to open.</p>
