Member Function Documentation

template<typename Reader>

std::vector< char >::size_type nds_impl::Socket::BufferedReader< Reader >::__buffered_bytes ( ) const

inline

A debugging function

Returns

Return the number of bytes in the current buffer

template<typename Reader>

void nds_impl::Socket::BufferedReader< Reader >::consume ( std::vector< char >::size_type  count )

inlineprivate

template<typename Reader>

void nds_impl::Socket::BufferedReader< Reader >::fill_buffer ( )

inlineprivate

template<typename Reader>

char* nds_impl::Socket::BufferedReader< Reader >::peek ( char *  start, const char *  end  )

inline

Return the next data (enough to fill [start, end)). No data will be removed from the internal buffer, only added if needed. The data will still be avaialble in the buffered reader for retreival.

Parameters

start	Start of the destination
end	Byte just past the end of the destination

Returns

end

template<typename Reader>

char* nds_impl::Socket::BufferedReader< Reader >::read_available ( char *  start, char *  end  )

inline

A read the data that is currently available. This will only result in a read on the underlying reader if the internal buffer is empty.

Parameters

start	Start address of the destination
end	Address of the byte past the last in the destination

Returns

A pointer in [start, end] that is the next location

template<typename Reader>

char* nds_impl::Socket::BufferedReader< Reader >::read_exactly ( char *  start, const char *  end  )

inline

Read exactly enough data to fill the range [start,end)

Parameters

start	Start of the destination
end	Byte just past the end of the destination

Returns

end

template<typename Reader>

template<typename It >

std::vector< char > nds_impl::Socket::BufferedReader< Reader >::read_until ( It  begin_set, It  end_set  )

inline

Read until a value in [begin_set,end_set) is found in the input stream.

Template Parameters

It	An iterator that dereferences chars

Parameters

begin_set	Start of the list of terminators
end_set	End of the list of terminators

Returns

A std::vector<char> of the data that was read in, including the terminator that was found.

This will retrieve data from the underlying reader as needed

template<typename Reader>

template<typename It , typename OutIt >

OutIt nds_impl::Socket::BufferedReader< Reader >::read_until ( It  begin_set, It  end_set, OutIt  dest_start, OutIt  dest_end  )

inline

Read until a value in [begin_set,end_set) is found in the input stream. This will write a bounded amount of data up to [dest_start, dest_end)

Template Parameters

It	An iterator that dereferences chars

Parameters

begin_set	Start of the list of terminators
end_set	End of the list of terminators
dest_start	Start of the destination
dest_end	one past the last destination point

This will retrieve data from the underlying reader as needed

template<typename Reader>

void nds_impl::Socket::BufferedReader< Reader >::write_all ( const char *  start, const char *  end  )

inline

Write data through to the underlying reader object.

Parameters

start	Bytes to start at
end	Address just past the last byte to send
