Constructor Details

VariableStorageManagerDB

public VariableStorageManagerDB(DBHandle handle,
 AddressMap addrMap,
 OpenMode openMode,
 ErrorHandler errorHandler,
 Lock lock,
 TaskMonitor monitor)
                         throws VersionException,
IOException,
CancelledException

Construct a new variable manager.

Parameters:

handle - the database handle.

addrMap - the address map (required for legacy adpter use only)

openMode - the open mode

errorHandler - database error handler

lock - the program synchronization lock

monitor - the task monitor.

Throws:

IOException - if a database error occurs.

VersionException - if the table version is different from this adapter.

IOException - if an IO error occurs

CancelledException - if the user cancels the upgrade.

Method Details

setProgramArchitecture

public void setProgramArchitecture(ProgramArchitecture arch)

Set program architecture.

Parameters:

arch - program architecture

delete

public static void delete(DBHandle dbHandle)
                   throws IOException

Delete the DB table which correspnds to this variable storage implementation

Parameters:

dbHandle - database handle

Throws:

IOException - if an IO error occurs

exists

public static boolean exists(DBHandle dbHandle)

Determine if the variable storage manager table already exists

Parameters:

dbHandle - database handle

Returns:

true if storage table exists

getVariableStorageAddress

public Address getVariableStorageAddress(VariableStorage storage,
 boolean create)
                                  throws IOException

Get a variable address for the given storage specification. NOTE: The program architecture and error handler must be set appropriately prior to invocation of this method (see setProgramArchitecture(ProgramArchitecture).

Specified by:

getVariableStorageAddress in interface VariableStorageManager

Parameters:

storage - variable storage specification

create - if true a new variable address will be allocated if needed

Returns:

variable address which corresponds to the storage specification or null if not found and create is false.

Throws:

IOException - if an IO error occurs

setLanguage

public void setLanguage(LanguageTranslator translator,
 TaskMonitor monitor)
                 throws CancelledException

Perform language translation. Following the invocation of this method it is important to ensure that the program architecure is adjusted if neccessary. Update variable storage specifications to reflect address space and register mappings

Parameters:

translator - language translator to be used for mapping storage varnodes to new architecture.

monitor - task monitor

Throws:

CancelledException - if task is cancelled
