Typedef Documentation

typedef std::pair<UnicodeEncodingForm, unsigned> EncodingInfo

EncodingInfo - Holds the encoding type and length of the byte order mark if it exists. Length is in {0, 2, 3, 4}.

Definition at line 39 of file YAMLParser.cpp.

typedef ilist<Token> TokenQueueT

Definition at line 177 of file YAMLParser.cpp.

typedef std::pair<uint32_t, unsigned> UTF8Decoded

The Unicode scalar value of a UTF-8 minimal well-formed code unit subsequence and the subsequence's length in code units (uint8_t). A length of 0 represents an error.
