public ELFHeaderDecoder(File file)

Constructor.

Parameters:

file - the ELF executable file

Method Detail

getExecutableType

public short getExecutableType()

Return the ELF 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

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
