Method Details

getMatchingPVs

public static LinkedList<String> getMatchingPVs(javax.servlet.http.HttpServletRequest req,
 ConfigService configService,
 int defaultLimit)

getMatchingPVs

public static LinkedList<String> getMatchingPVs(javax.servlet.http.HttpServletRequest req,
 ConfigService configService,
 boolean includePVSThatDontExist,
 int defaultLimit)

Given a BPL request, get all the matching PVs

Parameters:

req - HttpServletRequest

configService - ConfigService

includePVSThatDontExist - Some BPL requires us to include PVs that don't exist so that they can give explicit status

defaultLimit - The default value for the limit if the limit is not specified in the request.

Returns:

LinkedList Matching PVs

getRequestParameters

public static Map<String,String> getRequestParameters(javax.servlet.http.HttpServletRequest req)

Parameters:

pvs - List of pvs and regexes

regex - Single regex search

limit - Limit of query on pvs
