An RIFF file class with some useful methods specific to RIFF. More...
#include <rifffile.h>
Public Member Functions | |
virtual | ~File () |
Destroys this instance of the File. More... | |
![]() | |
FileName | name () const |
Returns the file name in the local file system encoding. More... | |
virtual Tag * | tag () const =0 |
Returns a pointer to this file's tag. More... | |
PropertyMap | properties () const |
Exports the tags of the file as dictionary mapping (human readable) tag names (uppercase Strings) to StringLists of tag values. More... | |
void | removeUnsupportedProperties (const StringList &properties) |
Removes unsupported properties, or a subset of them, from the file's metadata. More... | |
PropertyMap | setProperties (const PropertyMap &properties) |
Sets the tags of this File to those specified in properties. More... | |
virtual AudioProperties * | audioProperties () const =0 |
Returns a pointer to this file's audio properties. More... | |
virtual bool | save ()=0 |
Save the file and its associated tags. More... | |
ByteVector | readBlock (unsigned long length) |
Reads a block of size length at the current get pointer. More... | |
void | writeBlock (const ByteVector &data) |
Attempts to write the block data at the current get pointer. More... | |
long | find (const ByteVector &pattern, long fromOffset=0, const ByteVector &before=ByteVector()) |
Returns the offset in the file that pattern occurs at or -1 if it can not be found. More... | |
long | rfind (const ByteVector &pattern, long fromOffset=0, const ByteVector &before=ByteVector()) |
Returns the offset in the file that pattern occurs at or -1 if it can not be found. More... | |
void | insert (const ByteVector &data, unsigned long start=0, unsigned long replace=0) |
Insert data at position start in the file overwriting replace bytes of the original content. More... | |
void | removeBlock (unsigned long start=0, unsigned long length=0) |
Removes a block of the file starting a start and continuing for length bytes. More... | |
bool | readOnly () const |
Returns true if the file is read only (or if the file can not be opened). More... | |
bool | isOpen () const |
Since the file can currently only be opened as an argument to the constructor (sort-of by design), this returns if that open succeeded. More... | |
bool | isValid () const |
Returns true if the file is open and readable. More... | |
void | seek (long offset, Position p=Beginning) |
Move the I/O pointer to offset in the file from position p. More... | |
void | clear () |
Reset the end-of-file and error flags on the file. More... | |
long | tell () const |
Returns the current offset within the file. More... | |
long | length () |
Returns the length of the file. More... | |

static unsigned int | bufferSize () |
Returns the buffer size that is used for internal buffering. More... | |
An RIFF file class with some useful methods specific to RIFF.
This implements the generic TagLib::File API and additionally provides access to properties that are distinct to RIFF files, notably access to the different ID3 tags.
