Field Details

DBG_NAME

public static final String DBG_NAME

DBG files are portable executable (PE) format files that contain debug information in Codeview format for the Visual Studio debugger (and possibly other formats, depending on how the DBG was created). When you do not have source for certain code, such libraries or Windows APIs, DBG files permit debugging. DBG files also permit you to do OLE RPC debugging. Microsoft Corporation.

Method Details

findSupportedLoadSpecs

public Collection<LoadSpec> findSupportedLoadSpecs(ByteProvider provider)
                                            throws IOException

Description copied from interface: Loader

If this Loader supports loading the given ByteProvider, this methods returns a Collection of all supported LoadSpecs that contain discovered load specification information that this Loader will need to load. If this Loader cannot support loading the given ByteProvider, an empty Collection is returned.

Parameters:

provider - The bytes being loaded.

Returns:

A Collection of LoadSpecs that this Loader supports loading, or an empty Collection if this Loader doesn't support loading the given ByteProvider.

Throws:

IOException - if there was an IO-related issue finding the LoadSpecs.

load

public void load(ByteProvider provider,
 LoadSpec loadSpec,
 List<Option> options,
 Program prog,
 TaskMonitor monitor,
 MessageLog log)
          throws IOException

Description copied from class: AbstractLibrarySupportLoader

Loads bytes in a particular format into the given Program.

Specified by:

load in class AbstractLibrarySupportLoader

Parameters:

provider - The bytes to load.

loadSpec - The LoadSpec to use during load.

options - The load options.

prog - The Program to load into.

monitor - A cancelable task monitor.

log - The message log.

Throws:

IOException - if there was an IO-related problem loading.

getName

public String getName()

Description copied from interface: Loader

Gets the Loader's name, which is used both for display purposes, and to identify the Loader in the opinion files.

Returns:

The Loader's name.

supportsLoadIntoProgram

public boolean supportsLoadIntoProgram()

Description copied from interface: Loader

Checks to see if this Loader supports loading into an existing Program.

The default behavior of this method is to return false.

Returns:

True if this Loader supports loading into an existing Program; otherwise, false.

getDefaultOptions

public List<Option> getDefaultOptions(ByteProvider provider,
 LoadSpec loadSpec,
 DomainObject domainObject,
 boolean loadIntoProgram)

Description copied from interface: Loader

Gets the default Loader options.

Specified by:

getDefaultOptions in interface Loader

Overrides:

getDefaultOptions in class AbstractOrdinalSupportLoader

Parameters:

provider - The bytes of the thing being loaded.

loadSpec - The LoadSpec.

domainObject - The DomainObject being loaded.

loadIntoProgram - True if the load is adding to an existing DomainObject; otherwise, false.

Returns:

A list of the Loader's default options.

validateOptions

public String validateOptions(ByteProvider provider,
 LoadSpec loadSpec,
 List<Option> options,
 Program program)

Description copied from interface: Loader

Validates the Loader's options and returns null if all options are valid; otherwise, an error message describing the problem is returned.

Specified by:

validateOptions in interface Loader

Overrides:

validateOptions in class AbstractOrdinalSupportLoader

Parameters:

provider - The bytes of the thing being loaded.

loadSpec - The proposed LoadSpec.

options - The list of Options to validate.

program - existing program if the loader is adding to an existing program. If it is a fresh import, then this will be null.

Returns:

null if all Options are valid; otherwise, an error message describing the problem is returned.
