java.lang.Object

ghidra.app.util.bin.format.elf.info.ElfNote

ghidra.app.util.bin.format.elf.info.NoteGnuBuildId

All Implemented Interfaces:

ElfInfoItem

public class NoteGnuBuildId
extends ElfNote

An ELF note that specifies the build-id (sha1/md5/etc hash or manually specified bytes that can be hex-ified) of the containing program.

The hex values of the build-id are useful to find an external debug file.

Method Details

read

public static NoteGnuBuildId read(ElfNote note,
 Program program)
                           throws IOException

Deserializes a NoteGnuBuildId from an already read generic Note.

Parameters:

note - generic Note

program - context

Returns:

new NoteGnuBuildId instance, never null

Throws:

IOException - if data error

fromProgram

public static NoteGnuBuildId fromProgram(Program program)

Reads a NoteGnuBuildId from the standard ".note.gnu.build-id" section in the specified Program.

Parameters:

program - Program to read from

Returns:

new instance, or null if not found or data error

getNoteTypeName

public String getNoteTypeName()

Description copied from class: ElfNote

Returns a string that describes this note's type, used when creating the default ElfNote.getProgramInfoKey() value.

Specific Note subclasses can override this to return a better string than this default implementation, or can override the ElfNote.getProgramInfoKey() method.

Overrides:

getNoteTypeName in class ElfNote

Returns:

descriptive string

toStructure

public StructureDataType toStructure(DataTypeManager dtm)

Description copied from class: ElfNote

Returns a Structure datatype that matches the format of this ElfNote, or null if this ElfNote shouldn't be represented/marked up.

Overrides:

toStructure in class ElfNote

Parameters:

dtm - DataTypeManager that will receive the structure

Returns:

StructureDataType that specifies the layout of the ElfNote, or null
