1 | \section{\class{wxFileInputStream}}\label{wxfileinputstream} |
2 | ||
3 | This class represents data read in from a file. There are actually | |
4 | two such groups of classes: this one is based on \helpref{wxFile}{wxfile} | |
5 | whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in | |
6 | the \helpref{wxFFile}{wxffile} class. | |
7 | ||
8 | Note that \helpref{wxFile}{wxfile} and \helpref{wxFFile}{wxffile} differ | |
9 | in one aspect, namely when to report that the end of the file has been | |
10 | reached. This is documented in \helpref{wxFile::Eof}{wxfileeof} and | |
11 | \helpref{wxFFile::Eof}{wxffileeof} and the behaviour of the stream | |
12 | classes reflects this difference, i.e. wxFileInputStream will report | |
13 | wxSTREAM\_EOF after having read the last byte whereas wxFFileInputStream | |
14 | will report wxSTREAM\_EOF after trying to read {\it past} the last byte. | |
