Method Detail

delete

public static void delete(int cuid,
                          int addr)
                   throws java.sql.SQLException

Delete bytecode (should only be one) for cuID and address.

Throws:

java.sql.SQLException

deleteAll

public static void deleteAll(int cuid)
                      throws java.sql.SQLException

Delete all bytecode for cuID.

Throws:

java.sql.SQLException

fetchAddressesFor

public static java.util.ArrayList<java.lang.Integer> fetchAddressesFor(int cuid,
                                                                       Opcode opcode)
                                                                throws java.sql.SQLException

Fetch addresses for a particular Opcode in a cu.

Throws:

java.sql.SQLException

fetchAll

public static java.util.TreeMap<java.lang.Integer,Bytecode> fetchAll(int cuid)
                                                              throws java.sql.SQLException

Fetch all for a CU.

Throws:

java.sql.SQLException

fetchAllWithData

public static java.util.TreeMap<java.lang.Integer,Bytecode> fetchAllWithData(int cuid)
                                                                      throws java.sql.SQLException,
                                                                             java.io.IOException

Fetch all for a CU, with data bytes.

Throws:

java.sql.SQLException

java.io.IOException

fetchData

public static byte[] fetchData(int cuid,
                               int address)
                        throws java.sql.SQLException

Fetch the data bytes[] into a Bytecode object.

Throws:

java.sql.SQLException

fetch

public static Bytecode fetch(int cuid,
                             int address)
                      throws java.sql.SQLException

This does not populate the bytecode data field. That field is lazy-loaded.

Returns:

null if no matching record or if there is a bad Opcode.

Throws:

java.sql.SQLException

fetchOpcode

public static Opcode fetchOpcode(int cuid,
                                 int address)
                          throws java.sql.SQLException

This fetches the matching record and returns the Opcode enum. You might use this if you just need the Opcode for the address, but don't need to fetch the Bytecode object (a small amount less overhead).

Returns:

null if no matching record or if there is a bad Opcode.

Throws:

java.sql.SQLException

fetchOpcodes

public static java.util.TreeMap<java.lang.Integer,java.lang.Integer> fetchOpcodes(int cuid)
                                                                           throws java.sql.SQLException

Fetch a TreeMap of a compile unit's opcodes, sorted by address.

Throws:

java.sql.SQLException

fetchWithData

public static Bytecode fetchWithData(int cuid,
                                     int address)
                              throws java.sql.SQLException,
                                     java.io.IOException

Fetch the entire bytecode record, including the data in the bytes field.

Returns:

null if no matching record or if there is a bad Opcode.

Throws:

java.sql.SQLException

java.io.IOException

insert

public static void insert(java.util.Collection<Bytecode> list)
                   throws java.sql.SQLException,
                          java.io.IOException

Store a collection of Bytecode objects into the database. If the bytecode was originally from the database, then just the data segment is written (if modified). It is otherwise up to the application to make sure that it's not creating duplicate entries.

Throws:

java.io.IOException

java.sql.SQLException

insert

public static void insert(Bytecode bytecode)
                   throws java.sql.SQLException,
                          java.io.IOException

Store one Bytecode record. If this was originally from the database, then just the data segment is written (if modified). It otherwise is up to the application to make sure it's not creating duplicate entries.

Throws:

java.io.IOException

java.sql.SQLException

updateData

public static void updateData(Bytecode bytecode)
                       throws java.sql.SQLException,
                              java.io.IOException

Store changes to the parameters/data byte[] for an instruction that is already in the DB.

Throws:

java.io.IOException

java.sql.SQLException
