• 1st param: base URL (with trailing query parameter name e.g. "qd=")
• 2nd param: timeout (seconds)
• 3rd param: debug (int~bool)
• 4th param: map-mode (int~bool)

Here is the caller graph for this function:

expand()

void TxCab::expand ( const set< string > &  src, set< string > &  dst  )

Member Data Documentation

m_UrlBase

string TxCab::m_UrlBase

base URL; newline-separated query argument(s) will be appended for each expansion query

m_Debug

int TxCab::m_Debug

debug?

m_MapMode

int TxCab::m_MapMode

• if true ("map-mode"), argument term(s) must occur in the query response to be included in the output set
• otherwise ("union-mode", default), literal argument term(s) will always be included in output set
