class Extractor
Buffer wrapper for input of binary data from a buffer.
Subclassed by pdal::BeExtractor, pdal::LeExtractor, pdal::SwitchableExtractor
Public Functions
-
inline 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.
-
inline operator bool()
Determine if the buffer is good.
- Returns
Whether the buffer is good.
-
inline void seek(std::size_t pos)
Seek to a position in the buffer.
- Parameters
pos – Position to seek in buffer.
-
inline void skip(std::size_t cnt)
Advance buffer position.
- Parameters
cnt – Number of bytes to skip in buffer.
-
inline size_t position() const
Return the get position of buffer.
- Returns
Get position.
-
inline bool good() const
Determine whether the extractor is good (the get pointer is in the buffer).
- Returns
Whether the get pointer is valid.
-
inline 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.
-
inline 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.
-
inline 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.
-
inline 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.
-
inline 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.
