Method Details

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 AbstractLibrarySupportLoader

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 AbstractLibrarySupportLoader

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.

shouldSearchAllPaths

protected boolean shouldSearchAllPaths(Program program,
 List<Option> options,
 MessageLog log)

Description copied from class: AbstractLibrarySupportLoader

Checks whether or not to search for libraries using all possible search paths, regardless of what options are set

Overrides:

shouldSearchAllPaths in class AbstractLibrarySupportLoader

Parameters:

program - The Program being loaded

options - a List of Options

log - The log

Returns:

True if all possible search paths should be used, regardless of what options are set

processLibrary

protected void processLibrary(Program lib,
 String libName,
 FSRL libFsrl,
 ByteProvider provider,
 Queue<AbstractLibrarySupportLoader.UnprocessedLibrary> unprocessed,
 int depth,
 LoadSpec loadSpec,
 List<Option> options,
 MessageLog log,
 TaskMonitor monitor)
                       throws IOException,
CancelledException

Description copied from class: AbstractLibrarySupportLoader

Performs optional follow-on actions after an the given library has been loaded

Overrides:

processLibrary in class AbstractLibrarySupportLoader

Parameters:

lib - The loaded library Program

libName - The name of the library

libFsrl - The library FSRL

provider - The library bytes

unprocessed - The Queue of unprocessed libraries

depth - The load depth of the library to load

loadSpec - The LoadSpec used for the load

options - The options

log - The log

monitor - A cancelable monitor

Throws:

IOException - If an IO-related error occurred

CancelledException - If the user cancelled the action

postLoadProgramFixups

protected void postLoadProgramFixups(List<Loaded<Program>> loadedPrograms,
 Project project,
 LoadSpec loadSpec,
 List<Option> options,
 MessageLog messageLog,
 TaskMonitor monitor)
                              throws CancelledException,
IOException

Description copied from class: AbstractLibrarySupportLoader

This gets called after the given list of loaded programss is finished loading. It provides subclasses an opportunity to do follow-on actions to the load.

Fix up program's external library entries so that they point to a path in the project.

Overrides:

postLoadProgramFixups in class AbstractLibrarySupportLoader

Parameters:

loadedPrograms - The loaded programs to be fixed up.

project - The Project to load into. Could be null if there is no project.

loadSpec - The LoadSpec to use during load.

options - The load options.

messageLog - The message log.

monitor - A cancelable task monitor.

Throws:

CancelledException - if the user cancelled the load.

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

postLoadCleanup

protected void postLoadCleanup(boolean success)

Description copied from class: AbstractProgramLoader

This gets called as the final step of the load process. Subclasses may override it to ensure any resources they created can be cleaned up after the load finishes.

NOTE: Subclasses should not use this method to release any Programs they created when failure occurs. That should be done by the subclass as soon as it detects failure has occurred.

Overrides:

postLoadCleanup in class AbstractProgramLoader

Parameters:

success - True if the load completed successfully; otherwise, false
