Initialize a new connection thread

Method Detail

run

public void run()

Wait for connections (forever) parse clients requests and trigger the appropriate actions

Specified by:

run in interface java.lang.Runnable

Overrides:

public void getExtract(Request req,
              java.io.PrintWriter os)

Retrieve a bit of text surrounding a given keyword

Parameters:

req - A pre-parsed client request (key-value pairs)

os - the output stream (to be received by client)

See Also:

Request, TecCorpusFile

getHeaderBaseURL

public void getHeaderBaseURL(java.io.PrintWriter os)

getFreqList

public void getFreqList(Request req,
               java.io.PrintWriter os)

Retrieve a (case-insensitive) frequency list

Parameters:

req - A pre-parsed client request (key-value pairs)

os - the output stream (to be received by client)

getFreqWord

public void getFreqWord(Request req,
               java.io.PrintWriter os)

Retrieve the frequency of a keyword (possibly in a case-insensitive way). Parameters to be passed through the GET-like request by the client are: casesensitive to indicate whether case matters in searching for the keyword, and xquerywhere to specify subcorpus search constraints.
