executeParserOperation

public static <ResponseType> ResponseType executeParserOperation(RequestIds requestIds,
                                                 com.endeca.portal.mdex.LQLParserUtil.ParserOperator<ResponseType> op,

                                           throws DataSourceException,
                                                  LQLException

Throws:

DataSourceException

LQLException

setupNamedStates

protected static void setupNamedStates(com.endeca.mdex.eql_parser.types.ParseQuery parseQuery,
                    java.util.Collection<CollectionBaseView> baseViews)

Sets up named states for use as context when parsing queries with validation enabled. The set of named states should match those created in DiscoveryServiceUtil#setupNamedStates(com.endeca.mdex.conversation.Request, java.util.Collection).

Parameters:

parseQuery - a request to eql_parser

baseViews - collections in current project's context

Since:

3.2

DiscoveryServiceUtil#setupNamedStates(com.endeca.mdex.conversation.Request, java.util.Collection)

getOrCreateNamedState

protected static com.endeca.mdex.eql_parser.types.State getOrCreateNamedState(com.endeca.mdex.eql_parser.types.ParseQuery parseQuery,
                                                           java.lang.String stateName)

Tries to find the named state if it already exists on the parser request. If it doesn't yet exist, a new State is created and added to the request. Very similar to DiscoveryServiceUtil.getOrCreateNamedState(Request, String).

Parameters:

parseQuery - a request to eql_parser

stateName - name of a State to seek in parseQuery

Returns:

State matching specified name or a newly created one

Since:

3.2

getNamedState

protected static com.endeca.mdex.eql_parser.types.State getNamedState(com.endeca.mdex.eql_parser.types.ParseQuery parseQuery,
                                                   java.lang.String stateName)
                                                               throws StateNotFoundException

Find a named State in a parser service request. Very similar to DiscoveryServiceUtil.getNamedState(Request, String).

Parameters:

parseQuery - a request to eql_parser

stateName - name of the State to seek in req

Returns:

matching State

Throws:

StateNotFoundException - if the specified named state cannot be found in the Request

Since:

3.2
