Matches the closing bracket.

recursively converts all nodes inside a root node. Args: root_node (ET.Element): the root node to start the conversion.

converts a leaf node from V3 to V4. Args: node (ET.Element): the node to convert.

Converts the behavior tree V3 xml from in_file to V4, and writes to out_file. Args: in_stream (typing.TextIO): The input file stream.

@brief returns a const reverse iterator to the last element @sa https://json.nlohmann.me/api/basic_json/crbegin/

@brief returns a const reverse iterator to one before the first @sa https://json.nlohmann.me/api/basic_json/crend/

! @brief dump a floating-point number Dump a given floating-point number to output stream @a o. Works internally with @a number_buffer.

fill() is most frequently called with small byte counts (<= 4), which is why we're using loops rather than calling memset.

! For n != 0, returns k, such that pow10 := 10^(k-1) <= n < 10^k. For n == 0, returns 1 and sets pow10 := 1. */
