PeekCodePoint()

bool ON_TextIterator::PeekCodePoint

(

const

Parameters: unicode_code_point - [out] current unicode code point returned here. 0 = end of string Returns: true if returned unicode_code_point is not zero

ReadCodePoint()

bool ON_TextIterator::ReadCodePoint

(

ON__UINT32 &

unicode_code_point

)

Description: Gets the current unicode code point and calls Step() to advance the text iterator by one code point. Parameters: unicode_code_point - [out] current unicode code point returned here. 0 = end of string Returns: true if returned unicode_code_point is not zero

Step()

bool ON_TextIterator::Step

(

)

Get the next UNICODE code point encoded in m_text beginning at m_text[m_next_text_ci]; Save this code point in m_cur_codepoint. Advance m_next_text_ci.
