Method Details

getLinkerDataOffset

public int getLinkerDataOffset()

Description copied from class: LoadCommand

Gets the file offset of this load command's "linker data". Not all load commands with data will have linker data. Linker data typically resides in the __LINKEDIT segment.

Overrides:

getLinkerDataOffset in class LoadCommand

Returns:

The file offset of this load command's "linker data", or 0 if it has no linker data

getLinkerDataSize

public int getLinkerDataSize()

Description copied from class: LoadCommand

Gets the file size of this load command's "linker data". Not all load commands with data will have linker data. Linker data typically resides in the __LINKEDIT segment.

Overrides:

getLinkerDataSize in class LoadCommand

Returns:

The file size of this load command's "linker data", or 0 if it has no linker data

getCommandName

public String getCommandName()

Description copied from class: LoadCommand

Gets the name of this load command

Specified by:

getCommandName in class LoadCommand

Returns:

The name of this load command

markup

public void markup(Program program,
 MachHeader header,
 String source,
 TaskMonitor monitor,
 MessageLog log)
            throws CancelledException

Description copied from class: LoadCommand

Marks up this LoadCommand data with data structures and comments. Assumes the program was imported as a Mach-O.

Overrides:

markup in class LoadCommand

Parameters:

program - The Program to mark up

header - The Mach-O header

source - A name that represents where the header came from (could be null)

monitor - A cancellable task monitor

log - The log

Throws:

CancelledException - if the user cancelled the operation

markupRawBinary

public void markupRawBinary(MachHeader header,
 FlatProgramAPI api,
 Address baseAddress,
 ProgramModule parentModule,
 TaskMonitor monitor,
 MessageLog log)

Description copied from class: LoadCommand

Marks-up this LoadCommand with data structures and comments. Assumes the program was imported as a Raw Binary.

Overrides:

markupRawBinary in class LoadCommand

Parameters:

header - The Mach-O header

api - A FlatProgramAPI

baseAddress - The base address of the program

parentModule - The parent module to create fragments

monitor - A cancellable task monitor

log - The log

toDataType

public DataType toDataType()
                    throws DuplicateNameException,
IOException

Description copied from interface: StructConverter

Returns a structure datatype representing the contents of the implementor of this interface.

For example, given:

 class A {
     int foo;
     double bar;
 }
 

The return value should be a structure data type with two data type components; an INT and a DOUBLE. The structure should contain field names and, if possible, field comments.

Returns:

returns a structure datatype representing the implementor of this interface

Throws:

DuplicateNameException - when a datatype of the same name already exists

IOException
