Structtype objects contain a list of structfield objects that define the name, type, and nullable flag for each column in. Structtype objects define the schema of spark dataframes. Some operations are supported by several object types. The principal builtin types are numerics, sequences, mappings, classes, instances and exceptions. If you need to check the type of an object, it is better to use the python isinstance function instead. Clean preceeding and trailing whitespace in complex list.
The structure and test tools are mostly copied from csv data source for spark.
