Detailed Description

A class that provides a source for lines of text buffered in memory.

It keeps track of the current position in the buffer and allows retrieving lines one by one. The buffer is represented as a contiguous block of memory, and the class provides methods to access the lines without copying the data, using std::string_view. The class also stores a name for the source, which can be used for error reporting or debugging purposes.

Note

The buffer is not owned by the BufferLineSource, and it is the caller's responsibility to ensure that the buffer remains valid for the lifetime of the BufferLineSource object.

Member Function Documentation

initialize()

void delpi::BufferLineSource::initialize ( const char * data, std::size_t length )

protected

Force a reinitialization of the object, setting cur_ and end_ to the new values.

Parameters

data	new buffer of data
length	length of the new buffer

Definition at line 28 of file BufferLineSource.cpp.

nextLine()

bool delpi::BufferLineSource::nextLine

(

std::string_view &

out

)

Retrieve the next line from the buffer.

A line terminates with an '\n' or the end of the buffer. Moreover, if an '\r' character precedes the '\n' character, it is removed from the returned view.

Parameters

out	view of a line in the buffer, stripped of any newline characters

Returns

true if there is still some buffer left to read

false if the end of the buffer has been reached
