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