Wrapper around an AutoFile& that implements a ring buffer to deserialize from. It guarantees the ability to rewind a given number of bytes.
Declared in <streams.h>
class BufferedFile;Will automatically close the file when it goes out of scope if not null. If you need to close the file early, use file.fclose() instead of fclose(file).
| Name | Description |
|---|---|
BufferedFile [constructor] | Wrap a source file with a ring buffer of nBufSize bytes, guaranteeing nRewindIn bytes of rewind. |
FindByte | search for a given byte in the stream, and remain positioned on it |
GetPos | return the current reading position |
SetLimit | prevent reading beyond a certain position no argument removes the limit |
SetPos | rewind to a given reading position |
SkipTo | Move the read position ahead in the stream to the given position. Use SetPos() to back up in the stream, not SkipTo(). |
eof | check whether we're at the end of the source file |
operator>> | Deserialize an object from the buffered file and return this wrapper. |
read | read a number of bytes |
