~IStreamMem ()
size_t

readDataAvailable (void *dest, size_t maxSize)
void

seekAbsolute (off_t absoluteOffset)

Sets the current position of the stream to byte absoluteOffset . A negative offset is relative to the end of the file.
void

seekRelative (off_t relativeOffset)

Moves the current position of the stream by relativeOffset bytes.
off_t

tell () const

Returns the current offset into the stream in bytes.
off_t

size () const

Returns the total length of stream in bytes.
bool

isEof () const

Returns whether the stream is currently pointed at the end of the file.
const void *

getData ()

Returns a pointer to the data which the stream wraps.
void

read (T *t)
void

read (std::string *s)

Reads characters until a null terminator.
void

read (fs::path *p)
void

readEndian (T *t, uint8_t endian)

std::string

readLine ()
void

readData (void *dest, size_t size)
const fs::path &

getFileName () const

Returns the file name of the path from which a Stream originated when relevant. Empty string when undefined.
void

setFileName (const fs::path &aFileName)

Sets the file name of the path from which a Stream originated when relevant. Empty string when undefined.
bool

getDeleteOnDestroy () const

Returns whether the Stream has been requested to destroy its source upon its own destruction. For example, IStreamFile will delete its source file. Ignored in some types of streams. Defaults to false .
void

setDeleteOnDestroy (bool enable=true)

Sets whether the Stream has been requested to destroy its source upon its own destruction. For example, IStreamFile will delete its source file. Ignored in some types of streams. Defaults to false .

IStreamMemRef

create (const void *data, size_t size)

Creates a new IStreamMemRef from the memory pointed to by data which is of size size bytes.
uint8_t

getNativeEndianness ()

Returns the platform's endianness as a StreamBase::Endianness .
