Method Detail

addSessionSuper

public static void addSessionSuper(int cuid)
                            throws java.sql.SQLException,
                                   java.io.IOException

Ensure that a super CUID is indexed and cross referenced. Ensures that there is a DeclsnsupInstr record for the CUID. If it's not already there, then it's added, and cross reference updates are done for the procedure names it defines.

Throws:

java.sql.SQLException

java.io.IOException

checkForDropped

public static void checkForDropped()
                            throws java.sql.SQLException,
                                   java.io.IOException

Check if any session supers are no longer being instantiated as such. This is called at the start of Checkvals. We examine each of the bytecode instructions in CUID_SESSIONSUPERS, and if there are no xref links from an AddsnsuperInstr to it, then it is no longer being instantiated.

Throws:

java.sql.SQLException

java.io.IOException

lookupForProcNameID

public static java.util.HashSet<int[]> lookupForProcNameID(int procnameID)
                                                    throws java.sql.SQLException,
                                                           java.io.IOException

Lookup a set of session supers {cuid, procaddress} for a procedure name ID.

Returns:

An empty set if none found. (Does not return null.)

Throws:

java.sql.SQLException

java.io.IOException
