Class MachOHeaderDecoder

java.lang.Object

org.mdiutil.lang.MachOHeaderDecoder

All Implemented Interfaces:

HeaderDecoder

public class MachOHeaderDecoder
extends Object
implements HeaderDecoder

This class reads a Mach-O executable File to detect if this File is for a 64 bits or a 32 bits architecture. Note that Universal binaries formats are detected but not decoded.

MachOHeaderDecoder

public MachOHeaderDecoder(File file)

Constructor.

Parameters:

file - the Mach-O executable file

Method Detail

getExecutableType

public short getExecutableType()

Return the Mach-O File architecture. The possible returned values are:

• HeaderDecoder.EXE_INVALID: the value for invalid Portable Executable Files (can not exist, not being readable, or not being a valid Portable Executable File)
• HeaderDecoder.EXE_32BITS: the value for 32 bits executables
• HeaderDecoder.EXE_64BITS: the value for 64 bits executables
• HeaderDecoder.EXE_UNIVERSAL: the value for universal binaries executables

Specified by:

getExecutableType in interface HeaderDecoder

Returns:

the executable architecture

getEndianness

public short getEndianness()

Return the executable endianness. The possible returned values are:

• HeaderDecoder.ENDIAN_INVALID: the value if the indianess could be be detected
• HeaderDecoder.ENDIAN_LITTLE_ENDIAN: the value little-endian executable files
• HeaderDecoder.ENDIAN_BIG_ENDIAN: the value big-endian executable files

Specified by:

getEndianness in interface HeaderDecoder

Returns:

the executable endianness
