template<typename BasicJsonType>

strong

Enumerator
uninitialized	indicating the scanner is uninitialized
literal_true	the true literal
literal_false	the false literal
literal_null	the null literal
value_string	a string – use get_string() for actual value
value_unsigned	an unsigned integer – use get_number_unsigned() for actual value
value_integer	a signed integer – use get_number_integer() for actual value
value_float	an floating point number – use get_number_float() for actual value
begin_array	the character for array begin [
begin_object	the character for object begin {
end_array	the character for array end ]
end_object	the character for object end }
name_separator	the name separator :
value_separator	the value separator ,
parse_error	indicating a parse error
end_of_input	indicating the end of the input buffer
literal_or_value	a literal or the begin of a value (only for diagnostics)
