Abstract class for custom file input streams.
Definition: InputStream.hpp:40
virtual Int64 read(void *data, Int64 size)
Read data from the stream.
virtual Int64 tell()
Get the current reading position in the stream.
virtual Int64 seek(Int64 position)
Change the current reading position.
virtual ~FileInputStream()
Default destructor.
virtual Int64 getSize()
Return the size of the stream.
Utility class that makes any derived class non-copyable.
Definition: NonCopyable.hpp:35
bool open(const std::string &filename)
Open the stream from a file path.
FileInputStream()
Default constructor.
Implementation of input stream based on a file.
