Class CoffArchiveHeader

java.lang.Object

ghidra.app.util.bin.format.coff.archive.CoffArchiveHeader

All Implemented Interfaces:

StructConverter

public final class CoffArchiveHeader
extends Object
implements StructConverter

A class that represents a COFF archive file (ie. MS .lib files, Unix .ar files)

COFF archives are very primitive compared to containers like ZIP or even TAR.

The name of entries (ie. files) inside the archive is limited to 16 bytes, and to support longer names a couple of different schemes have been invented. See the comments in CoffArchiveMemberHeader.read(BinaryReader, LongNamesMember) for decoding the name.

Method Details

isMatch

public static boolean isMatch(ByteProvider provider)
                       throws IOException

Returns true if the data contained in the provider contains a COFF Archive file.

Parameters:

provider -

Returns:

Throws:

IOException

read

public static CoffArchiveHeader read(ByteProvider provider,
 TaskMonitor monitor)
                              throws CoffException,
IOException

Reads and parses the headers and meta-data in a COFF Archive file.

Returns a CoffArchiveHeader that has a list of the members in the archive.

Parameters:

provider -

monitor -

Returns:

Throws:

CoffException

IOException

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.

Specified by:

toDataType in interface StructConverter

Returns:

returns a structure datatype representing the implementor of this interface

Throws:

DuplicateNameException - when a datatype of the same name already exists

IOException - if an IO-related error occurs
