Detailed Description

template<typename StringT = CTTL_STD_STRING>
class cttl_impl::xtl_text_container_impl< StringT >

defines core functionality of the CTTL text container class.

StringT

Template parameter specifying type of the encapsulated string. The default is std::string

Member Function Documentation

size_t line_2_offset (  int  line_  )  const [inline, protected]

Converts line number to offset. Parameters: line_  Source line number to be converted to the offset Returns: Offset corresponding to the beginning of the source line. Postcondition: If specified source line number is too big (there is no such line) then the returned offset is length of the encapsulated string, xtl_text_container_impl::m_client_str. Definition at line 146 of file xtl_container_impl.h.

size_t offset_2_line (  size_t  offset_  )  const [inline, protected]

Converts specified offset_ to the line number. Complexity linear. Exactly last - first comparisons. Definition at line 164 of file xtl_container_impl.h.

size_t offset_2_line_end_offset (  size_t  offset_  )  const [inline, protected]

Converts specified offset_ to the offset of the current line end offset. Complexity: linear. The following diagram demonstrates how line numbers are calculated: one\r\ntwo 111----222- B E B E Definition at line 220 of file xtl_container_impl.h.

size_t offset_2_line_home_offset (  size_t  offset_  )  const [inline, protected]

Converts specified offset_ to the offset of the current line home offset. Complexity linear. The following diagram demonstrates how line numbers are calculated: one\r\ntwo 111----222- B E B E Definition at line 197 of file xtl_container_impl.h.

size_t offset_2_next_line_offset (  size_t  offset_  )  const [inline, protected]

Converts specified offset_ to the offset of the next line home offset. Complexity linear. Definition at line 177 of file xtl_container_impl.h.
