\class ListBuilder \brief Builder class for variable-length list array value types To use this class, you must append values to the child array builder and use the Append function to delimit each distinct list value (once the values have been appended to the child array) or use the bulk API to append a sequence of offsets and null values. A note on types. Per arrow/type.h all types in the c++ implementation are logical so even though this class always builds list array, this can represent multiple different logical types. If no logical type is provided at construction time, the class defaults to List where t is taken from the value_builder/values that the object is constructed with.
