Detailed Description

Read bytes from a file, usually text.

This is basically a simple wrapper around FILE structures, with correct closing and error checking. Mostly provided because I always forget how to interact with ifstream objects when I want a sequence of bytes.

Constructor & Destructor Documentation

RawFileReader() [1/2]

byteme::RawFileReader::RawFileReader ( const char * path, size_t buffer_size = 65536 )

inline

Parameters

path	Path to the file.
buffer_size	Size of the buffer to use for reading.

RawFileReader() [2/2]

byteme::RawFileReader::RawFileReader ( const std::string & path, size_t buffer_size = 65536 )

inline

Parameters

path	Path to the file.
buffer_size	Size of the buffer to use for reading.

Member Function Documentation

available()

size_t byteme::RawFileReader::available ( ) const

inlinevirtual

This method should only be called after load() has been called and returns true. The return value is generally expected to be positive; however, it is possible to return a zero. Note that zero values should not be interpreted as the end of the source, which is strictly only defined by load() returning false.

Returns

Number of available bytes in buffer().

Implements byteme::Reader.

buffer()

const unsigned char * byteme::RawFileReader::buffer ( ) const

inlinevirtual

This method should only be called after load() has been called and returns true.

Returns

Pointer to the start of an array containing the available bytes. The number of available bytes is provided in available().

Implements byteme::Reader.

load()

bool byteme::RawFileReader::load ( )

inlinevirtual

Read the next chunk of bytes from the input source. To read the entire source, this function should be called repeatedly until false is returned.

Returns

Boolean indicating whether the read was successful. If false, it can be assumed that the end of the source was reached.

Implements byteme::Reader.
