class
Extractor¶ Buffer wrapper for input of binary data from a buffer.
Subclassed by pdal::BeExtractor, pdal::LeExtractor, pdal::SwitchableExtractor
Public Functions
-
Extractor(const char *buf, std::size_t size)¶ Construct an extractor to operate on a buffer.
- Parameters
buf: Buffer to extract from.size: Buffer size.
-
operator bool()¶ Determine if the buffer is good.
- Return
Whether the buffer is good.
-
void
seek(std::size_t pos)¶ Seek to a position in the buffer.
- Parameters
pos: Position to seek in buffer.
-
void
skip(std::size_t cnt)¶ Advance buffer position.
- Parameters
cnt: Number of bytes to skip in buffer.
-
size_t
position() const¶ Return the get position of buffer.
- Return
Get position.
-
bool
good() const¶ Determine whether the extractor is good (the get pointer is in the buffer).
- Return
Whether the get pointer is valid.
-
void
get(std::string &s, size_t size)¶ Extract a string of a particular size from the buffer.
Trim trailing null bytes.
- Parameters
s: String to extract to.size: Number of bytes to extract from buffer into string.
-
void
get(std::vector<char> &buf)¶ Extract data to char vector.
Vector must be sized to indicate number of bytes to extract.
- Parameters
buf: Vector to which bytes should be extracted.
-
void
get(std::vector<unsigned char> &buf)¶ Extract data to unsigned char vector.
Vector must be sized to indicate number of bytes to extract.
- Parameters
buf: Vector to which bytes should be extracted.
-
void
get(char *buf, size_t size)¶ Extract data into a provided buffer.
- Parameters
buf: Pointer to buffer to which bytes should be extracted.size: Number of bytes to extract.
-
void
get(unsigned char *buf, size_t size)¶ Extract data into a provided unsigned buffer.
- Parameters
buf: Pointer to buffer to which bytes should be extracted.size: Number of bytes to extract.
