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,
CancelledException

Description copied from class: AbstractProgramWrapperLoader

Loads bytes in a particular format into the given Program.

Specified by:

load in class AbstractProgramWrapperLoader

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.

CancelledException - if the user cancelled the load.

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.
