Detailed Description

TODO: For now, our parse_url may not behave exactly like Hive when given malformed URLs. If necessary, we can closely follow Java's URL implementation to behave exactly like Hive. Example for explaining URL parts: http://user:pass@example.com:80/docs/books/tutorial/index.html?name=networking#DOWNLOADING PROTOCOL = http AUTHORITY = example.com:80 HOST = example.com PATH = /docs/books/tutorial/index.html QUERY = name=networking FILENAME = /docs/books/tutorial/index.html?name=networking REF = DOWNLOADING USERINFO = user:pass More details on what exactly the URL parts mean can be found here: http://docs.oracle.com/javase/tutorial/networking/urls/urlInfo.html

Member Function Documentation

UrlParser::UrlPart impala::UrlParser::GetUrlPart ( const StringValue &  part)
static

Compares part against url_authority, url_file, url_host, etc., and returns the corresponding enum. If part did not match any of the url part constants, returns INVALID.

bool impala::UrlParser::ParseUrl ( const StringValue &  url,
UrlPart  part,
StringValue *  result 
)
static

Tries to parse the part from url. Places the result in result. Returns false if the URL is malformed or if part is invalid. True otherwise. If false is returned the contents of results are undefined.

bool impala::UrlParser::ParseUrlKey ( const StringValue &  url,
UrlPart  part,
const StringValue &  key,
StringValue *  result 
)
static

Tries to parse key from url. Places the result in result. Returns false if the URL is malformed or if part is invalid. True otherwise. If false is returned the contents of results are undefined.
